INTRODUCTIONFLAT BOTTOM AND HOPPER TOP 1.1. FLAT BOTTOM BINS1. IntroductionThis manual describes how to assemble the following the following 4” corrugated storage bins:• Flat Bottom Bins, Stiffened 18’ to 60’• Flat Bottom Bins, Unstiffened 15’ to 48’• Hopper Bin Tops, Unstiffened 15’ to 24’• Hopper Bin Tops, Stiffened 15’ to 27’Before assembly, read this manual and familiarize yourself with the process and the necessary precautions for efficient and safe assembly. Anyone present at the assembly site is required to be familiar with all safety precautions and require-ments. Keep this manual handy for frequent reference and to review with new personnel. Call your local distributor or dealer if you need assistance or additional information.1.1. FLAT BOTTOM BINSFlat bottom bins are shipped as a complete product to be assembled on a customer-provided concrete foundation, and includes standard hardware required to secure the bin to the foundation (anchor bolts, stiffener baseplates for stiffened bins).1.2. HOPPER BIN TOPSHopper bin tops are designed to be connected to a hopper bottom (hopper cone and support legs) that has been engineered to support the live and dead loads that the hopper bin is expected to bear. Hopper bin tops can be ordered with or without a hopper bottom. If ordered with a hopper bottom, a hopper bottom that is specifically approved for use with the hopper top can be provided (structurally and for mechanical fit).Important: For stiffened hopper bin tops, it is important that the bottom edge of all stiffeners on the hopper top connect to the hopper bottom in such a way that the vertical loads of the stiffeners are transferred directly to the hopper bottom. Approved hopper bottoms will provide specific instructions.Important: For use of hopper bottoms that have not been specifically approved, contact your distributor or sales representative for technical information that is required to ensure appropriate fit, structural capacity, and stiffener load transfer (e.g. brackets, baseplates, or shims).ENM-18910 R0 51.

PRE-ASSEMBLYFLAT BOTTOM AND HOPPER TOP 3.1. SITE SELECTION3. Pre-Assembly 3.1. SITE SELECTIONThe selection of the site is very important. The following must be adhered to when choosing a bin site:• Choose a firm, level, well-drained site, so that snow/water cannot collect near the grain bin.• The soil on the site needs a bearing capacity adequate for the bin foundation design. Check bearing capacity if there is any doubt about its adequacy. Always consult with an engineer who is familiar with local soil conditions.• Bins should be clear from power lines or electrical transmission equipment. Contact your local power company to obtain recommended equipment clear-ance information.• Ensure that there is sufficient power available to operate any aeration or unload equipment that is to be installed.• Orientation: Consider door placement (if equipped), vent sheet placement, loading auger direction, and unloading auger direction when choosing a site.• Hammer drill for drilling anchor bolt holes.3.2. SITE PLAN VERIFICATIONBefore beginning to assemble the grain bin, a site plan must be completed. The complexity of the site plan will depend on the size of the installation (a single bin vs multiple) and should include the following details, where applicable:• Bin location(s), clearly and accurately identified.• Bin features such as door and ladder locations are also clearly marked, as well as the location of roof features (e.g. indicate where inspection panels, vent panels, and roof ladders will be located).• Any hazards (such as low electrical lines) must be identified clearly.3.3. FOUNDATIONBefore assembling the bin, the foundation must be completed. The bin foundation must be built on a site with good drainage, prepared by removing top soil and organic material and replacing this with granular fill. The fill shall be compacted and must have a minimum soil bearing capacity of 3000 lbs per square foot [144 kPa]. Concrete shall have a minimum compressive strength of f'c = 3000 psi [20 MPa] at 28 days. When constructing a foundation for the grain bin, local code and jurisdiction requirements that apply to the grain bin installation must be adhered to, as well Warning: Before continuing, please reread the safety information relevant to this section in the safety section of this manual. Failure to follow the safety instructions can result in serious injury, death, or property damage.ENM-18910 R0 13as the design and construction requirements listed in this manual.3. PRE-ASSEMBLY 4" CORRUGATED STORAGE BINS, STIFFENED AND UNSTIFFENED3.4. CHECK SHIPMENT FLAT BOTTOM AND HOPPER TOPFoundations must be designed for the highest loads that they are expected to support, given the local soil conditions. Foundation guidelines are provided for a set of minimum soil conditions that may not be applicable to all local conditions.The foundation must provide uniform and level support for the grain bin. Before assembling a grain bin, ensure that the bin foundation is complete and meets specifications for levelness and correct dimensions. The foundation must be level to within 1/4" in 10' [6 mm in 3 m] and 1/2" [12 mm] overall variation. Construction errors or imperfections that cause high or low spots must be remedied, and may require level removal of concrete, use of shims, or parging of low areas.3.4. CHECK SHIPMENTUnload the bin parts at the assembly site and compare the packing slip to the shipment. Ensure that all items have arrived and that none are damaged. It is important to report missing or damaged parts immediately to ensure that proper credit is received from either the manufacturer or from your distributor/dealer, and to ensure that any missing parts can be shipped quickly to avoid holding up the assembly process. 3.5. STORAGE OF MATERIALSSidewall sheets, roof sheets, and roof structural members are made of galva-nized steel (steel that is coated with zinc to provide protection from rust). If moisture (rain or condensation) gets in between the materials, or is allowed to accumulate on materials, and is not dried immediately, “white rust” can form, reducing or removing the zinc layer that protects the steel from destructive and structurally dangerous “red rust.” 3.5.1. LONG-TERM STORAGE OF MATERIALS (INDOOR ONLY)• Store all materials in a dry indoor environment where there is no risk of leaks or flooding (wall-sheet bundles, roof sheets, bin-boxes, ladder boxes, and hardware boxes). • If there is any risk of leaks or flooding at an indoor storage location, cover with a well-secured water-proof tarp that is wrapped to provide venting (allows a protected exchange of air to prevent build-up of moisture under the tarp).• Raise all materials 6” to 8” above floor level.• Elevate roof sheets 12” at the narrow end of the sheets during long-term stor-age. 14 ENM-18910 R04" CORRUGATED STORAGE BINS, STIFFENED AND UNSTIFFENED 3. PRE-ASSEMBLYFLAT BOTTOM AND HOPPER TOP 3.6. LIFTING BIN DURING CONSTRUCTION3.5.2. TEMPORARY STORAGE OF MATERIALS (INDOOR AND OUTDOOR)• Temporary indoor storage does not require special concern, apart from stor-ing in a dry environment where there is no risk of leaks or floods.• Temporary outdoor storage (i.e. on site, or associated with transport) requires all parts to be covered with a waterproof tarp that is wrapped to provide vent-ing (allows a protected exchange of air to prevent build-up of moisture under the tarp). Raise all materials at least 6” to 8” above ground or floor level.3.5.3. IF PARTS BECOME WETTo prevent white rust, follow the instructions below.• Open bundles as soon as possible.• Separate and stand materials upright, wipe dry, and let stand for a minimum of 24 hours to ensure dryness.Brace materials properly to avoid damage or injury from material falling when in storage.• Wipe down wall sheets and apply petroleum jelly or food-grade oil with a clean, lint-free cloth. • If left uncared for, white rust can turn into red rust, which can be a structural concern. Immediately replace any part with red rust on it.3.6. LIFTING BIN DURING CONSTRUCTIONBin jacks used to lift a bin during construction must be rated for the weight, diameter, and design of the bin. Refer to the jack manufacturer for safe working loads for lifting a specific bin model, as well as the minimum number of jacks required to support a specific bin model. See the bin specifications in the Appendix for bin model weights.To avoid the possibility of wind-related damage to the bin, always lower the bin and secure it to the foundation when active assembly is not taking place.NOTICE Do NOT use oil or petroleum jelly on roof or ladder materials.WARNINGRed rust has the potential to become a structural concern. Failure to immediately replace any part with red rust may result in the collapse of structure.Failure to protect against the effects of moisture will void your warranty.Note:ENM-18910 R0 153.

RESTRICTIONS ON OPENINGS IN THE BINCutting openings in the bin sidewall to accommodate an aeration fan or unload system may affect the structural stability of the bin, so specific restrictions must be observed. If one or more opening has to be made in the bin sidewall:• The maximum opening size is 72.5” x 12.5” (width x height). Openings for aeration fans should not exceed the required width of the fan transition by more than 0.5”.• An opening must not cut through a vertical seam between two sheets or a stiffener position.• A minimum 45° angle of separation between the centre-points of any two openings must be respected, including the hole cut for the bin unload.• For unstiffened bins, a minimum distance of 12” should separate a wall sheet vertical seam from the edge of an opening.Figure 3.1 Example of Angle of Separation From a Bin Unload OpeningFigure 3.2 Restrictions for Opening Size and Distance from Vertical Seam 45° MINIMUMOPENINGS NOTALLOWEDOPENINGS ALLOWEDXBIN UNLOADOPENINGX 12” MINIMUM, UNSTIFFENED BINS ONLY 72.5”12.5”VERTICALSEAMADJOININGSHEETADJOININGSHEETOPENINGSIDEWALL SHEET (DOES NOT APPLY TO STIFFENED BINS)ENM-18910 R0 173.

ASSEMBLY 4" CORRUGATED STORAGE BINS, STIFFENED AND UNSTIFFENED4.4. ASSEMBLING THE TOP SIDEWALL RING FLAT BOTTOM AND HOPPER TOP4.4. ASSEMBLING THE TOP SIDEWALL RINGImportant: Refer to the model-specific sheet layout information provided separately before proceeding. Procedures for assembling the top sidewall ring vary slightly depending on bin type (flat bottom or hopper). Follow the appropriate procedure below to assemble the top sidewall ring:• “Assemble the Flat Bottom Bin Top Sidewall Ring” on page 40• “Assemble the Hopper Bin Top Sidewall Ring” on page 434.4.1. ASSEMBLE THE FLAT BOTTOM BIN TOP SIDEWALL RINGRotating the bin once it is assembled (even slightly) is very difficult and dangerous, so it is important to pre-plan bin component positions before connecting bin sheets together, and avoid any need to rotate the bin. For stiffened bins, if bin anchors have not been pre-installed, locations for drilling holes for anchors should be marked, and placement of bin sheets must align stiffener/baseplate locations with bin anchors.It is critical to mark the door position (normally in line with the bin unload) before proceeding with connecting bin sheets. Make sure that the door position is clearly marked. For bins with an even number of tiers, the centre of the door will be located below a vertical seam between top-tier bin sheets. For bins with an odd number of tiers, the centre of the door will be located below the middle of a top-tier bin sheet. For detailed information about the placement of anchor bolts, see “Mounting Flat Bottom Bin to Foundation (Stiffened)” on page 139 and “Mounting Flat Bottom Bin to Foundation (Unstiffened)” on page 143.1. Find the centre of concrete foundation, and mark the ring circumference on the concrete foundation. Refer to Table 4.6 below for bin wall radius.Figure 4.25 Mark Bin Circumference on Concrete FoundationEXACT CENTRE OF RADIUS OF BINFOUNDATION40 ENM-18910 R04" CORRUGATED STORAGE BINS, STIFFENED AND UNSTIFFENED 4. ASSEMBLYFLAT BOTTOM AND HOPPER TOP 4.4. ASSEMBLING THE TOP SIDEWALL RING2. Mark stiffener locations, bin sheet positions, ladder position, door position and any other bin features on the concrete foundation for reference.Table 4.6 Bin Wall Radius 3. Connect the sidewall sheets around the circle marked in Step 1., forming the first tier, as follows: • Caulk the vertical and horizontal edges on the right hand side of each sheet (as seen from the inside of the bin circle) before connecting another bin sheet as follows: fully down the vertical seam, caulking centred between the edge of the bolt holes and the outside edge of the sheet, and 8 inches horizontally at the bottom of the sheet. See Figure 4.26 for details. • Place sheets in a clockwise direction, one sheet at a time, lapping each new sheet toward the centre of the bin.• Ensure that sheets are placed accurately on the line that marks the sidewall ring position. • Ensure that all sheets remain in their place as additional sheets are added. Note: For ease of construction, bolt sheets together with three or four bolts (finger tight) per seam, until all bin sheets have been connected, then follow up with all remaining bolts. Important: Before each additional tier is added, the tier above must be complete: all sheets placed, bolts filled, and nuts tightened.4. Where required, ensure that sidewall features on the top tier are installed at this time, such as ladder components or stiffeners (see the appropriate section of this manual for instructions). 5. Insert all remaining bin bolts and nuts, and tighten fully.Bin Diameter(Nominal) Bin Wall Radius15’ 7’ 5.5” (2.28 m)18’ 8’ 11.5” (2.73 m)21’ 10’ 5.5” (3.19 m)24’ 11’ 11” (3.64 m)27’ 13’ 5” (4.1 m)30’ 14’ 11” (4.55 m)33’ 16’ 5” (5 m)36’ 17’ 11” (5.45 m)42’ 20’ 10.5” (6.37m)48’ 23’ 10.5” (7.28 m)54’ 26' 10.5" (8.2 m)60’ 29’ 10” (9.10 m)ENM-18910 R0 414.

ASSEMBLE THE HOPPER BIN TOP SIDEWALL RING Rotating the bin once it is assembled (even slightly) is very difficult and dangerous, so it is important to pre-plan bin component locations.The completed hopper bin top must be lifted and moved onto the hopper bottom, so it is important to locate the two sections of the hopper bin as close as possible to one another, in order to make moving the hopper top more convenient.1. Fully construct the hopper bottom on the foundation, and ensure that the hopper bottom is secured to the foundation as required using appropriate anchor bolts or other connectors. 2. Construct the top tier of sidewall sheets near the hopper bottom, as follows:• Mark the approximate diameter of the hopper top sidewall on the ground, to provide guidance for sheet placement as the first tier is constructed.• Caulk the vertical and horizontal edges on the right hand side of each sheet (as seen from the inside of the bin circle) before connecting another bin sheet as follows: fully down the vertical seam, caulking centred between the edge of the bolt holes and the outside edge of the sheet, and 8” horizontally at the bottom of the sheet. See Figure 4.27 for details. • Place sheets in a clockwise direction, one sheet at a time, lapping each new sheet toward the centre of the bin. Note: For ease of construction, bolt sheets together with three or four bolts (finger tight) per seam, until all bin sheets have been connected, then follow up with all remaining bolts. Important: Before each additional tier is added, the tier above must be complete: all sheets placed, bolts filled, and nuts tightened.3. Where required, ensure that sidewall features on the top tier are installed at this time, such as ladder components or stiffeners (see the appropriate section of this manual for instructions). 4. Insert all remaining bin bolts and nuts, and tighten fully.ENM-18910 R0 434. ASSEMBLY 4" CORRUGATED STORAGE BINS, STIFFENED AND UNSTIFFENED4.4.

INSTALLING THE ROOF ANGLE SECTIONS AND EAVE BRACESThe roof angle sections install on the top inside edge of the top tier of sidewall sheets, and are used to fasten the roof sheets to the bin wall, and bolt into place using bolts and nuts specified for the top row in that sidewall sheet.? Eave braces are only required on 60’ bins. The eave braces install with the roof angle sections at each roof rib location where a rib stiffener is required. As shown in Figure 4.29, install eave braces with the support flange over each roof rib position (positions 2, 6, 10, where birdstops install).Important: To ensure correct alignment of roof ladder and sidewall ladder, the roof angle sections must be installed beginning at the 6th bolt hole position from the left of each sheet (as determined facing the bin wall from the outside of the ring). Failure to do so may lead to misalignment of ladder components.When installing the roof angle sections on the sheet that includes the sidewall ladder, ladder standoffs typically install in bolt positions 7 and 9 (see Figure 4.28 below) at the same time. 1. Position the first roof angle section on the inside of the top edge of a bin sheet, aligned so that the first bolt hole on the left hand side of the section aligns with the 6th bolt hole from the left hand side of the sheet (as seen from the outside of the bin).2. Use a few bolts to connect the angle section. ? 3. Eave braces are used in 60’ bins only, and install in every rib position that requires a rib stiffener (see “Installing Rib Stiffeners” on page 61). Each eave brace requires two bolt hole positions for installation (locations are bolt holes 2&3, 6&7, 10&11, depending on configuration (stiffeners in every rib vs. every second rib), but only a single bolt should be used (in odd numbered holes 3, 7 & 11) until birdstops are installed, because they share the same bolt, see Figure 4.29.Figure 4.28 Installing Roof Angle Sections on the Ladder Sheet1062 7 9ROOF ANGLE SECTION ALIGNSWITH BOLT HOLE NUMBER 6.13121185431VIEW FROM OUTSIDE OF BINNOTE: FOR 60’ BINS, EAVE BRACES MAY BE INSTALLED IN BOLT HOLES 2&3, 6&7, 10&11, LADDER STANDOFFS DEPENDING ON THE ROOF RIB STIFFENER CONFIGURATION.

POSITIONING THE ROOF PEAK SUPPORTRoof peak support is provided either by a filler cap assembly (15-36’ bins), with or without a filler cap adaptor (33’ and 36’ bins), or by a compression ring (42’-60’ bins).Before the roof can be constructed, the peak support must be elevated in the centre of the bin at the appropriate height relative to the foundation. This provides a guide for the correct fit for roof sheets, and supports the sheets as they are installed.To position the roof peak support:1. Erect roof peak support positioning equipment in the exact center of the sidewall ring. Typically this is an adjustable-height centre-post based design, but any suitably engineered system can be used. 2. Raise and support the roof filler cap (bin diameters 15’-36’) or compression ring (bin diameters 42’, 48’, 54’, and 60’) in the centre of the bin at the height shown in Table 4.7. For 33’ and 36’ bins, install the filler cap adaptor first.Figure 4.32 Height of Compression Ring on Centre PostCAUTIONPeak support positioning equipment must be designed to safely support the full vertical load of the roof, and withstand the sideways tipping force that will occur as the first four roof segments are installed.COMPRESSION RING (42’,48’, 54’, 60’ BINS) OR FILLER CAP THROAT (15’-36’ BINS)HEIGHT ENM-18910 R0 494.

INSTALLING ROOF SHEETSOverlap new roof sheets in a counter-clockwise direction, sheeted in segments (see procedure starting at “Step 1: Install Roof Sheets in Sections” on page 57).Roof sheet ribs MUST align with bolt holes 2, 6, and 10 on the top of the bin sidewall sheet, as measured from the left hand side of the outside of a top-tier sidewall sheet (see Figure 4.34). Vent sheets are optional, and are installed based on specific requirements specified by the customer. Unless instructed otherwise, install vent sheets equally spaced around the roof.Bolt roof sheets in the following order:• Top (rib to filler cap or compression ring): see Figure 4.34 (15-36’ bins) or Figure 4.35 (42-60’ bins), bolted loosely until throat clips are installed.• Bottom (sidewall): see Figure 4.37• Middle (rib to rib): see Figure 4.38 LADDERThe roof ladder aligns with the sidewall ladder, and the inspection hatch sheet must be placed directly to the right the roof ladder sheet. You can install the roof ladder rungs only after roof sheets have been installed on both sides of the designated ladder sheet. See “Installing the Roof Ladder” on page 83) for instructions.ROOF CLEATSInstall roof cleats as sheets are added. See “Installing Roof Cleats” on page 85 for detailed installation instructions.ROOF RINGSLeave the bolt holes where the roof ring brackets install empty while sheeting the roof, and install brackets and bolts at the same time that the rings are installed. See “Installing External Roof Rings” on page 103 for detailed installation instruc-tions.42’- 60’ BIN STIFFENED RIB SPACER? For 42’ - 60’ bins, a small spacer must be used on every bolt that is used to connect a roof rib stiffener to a roof rib. This means that before sheeting the roof, before bolting ribs together, you must determine which roof ribs will require rib stiffeners, and which ones will not.

ASSEMBLYFLAT BOTTOM AND HOPPER TOP 4.8. INSTALLING ROOF SHEETSSTEP 1: INSTALL ROOF SHEETS IN SECTIONSNote: Roof sheets should be installed in sections evenly spaced around the bin wall, in order to evenly distribute weight as the roof is assembled. The figure below provides some recommendations for the number of sections for each bin size, but more sections can be used if desired.1. Review the planned positions of roof components such as the filler cap, (direction of lid opening), inspection hatch sheet, roof ladder, and vent sheets.? 2. For 42’-60’ bins, determine which roof ribs will require rib stiffeners (see “Installing Rib Stiffeners” on page 61 for details), and make sure that for ribs that will require rib stiffeners, a spacer (202-3067) is used on every bolt (see Figure 4.33, Figure 4.35, and Figure 4.38 for details).3. Begin the sections by bolting a roof sheet in place for each section. Place the sheets equally spaced around the bin the sidewall sheets and the filler cap (15-36’ bins) or compression ring (42’-60’ bins). Count bolt holes and sheet positions to ensure that opposing sheets are directly opposite: ? • For 15’ to 36’ bins, each roof sheet location is matched by four roof angle bolt holes on the sidewall, and by two bolt holes in the filler cap throat (15’ to 30’) or filler cap adaptor (33’ and 36’ roofs). See Figure 4.34 for detail.?? • For 42’-60’ bins, each roof sheet location is matched by four roof angle bolt holes on the sidewall, and by two brackets at the compression ring. See Figure 4.35 for detail.

Depending on the roof diameter, each rib stiffener is composed of one or more main sections, with sections connected by one or more splice plates.Rib stiffeners install in either every roof rib, or every second rib, depending on the roof load option selected (see Table 4.8), and connect to the roof by a second (or “double”) nut on the existing roof bolts in the roof ribs.Important: When rib stiffeners are installed in every second rib, special considerations must be made, depending on the number of roof sheets (odd or even). For 27’ and 33’ bins (odd number of roof sheets), install stiffeners in both ladder sheet ribs, then proceed to install in every second rib. For all other bins, (even number of roof sheets), begin with the right-hand rib of the inspection hatch sheet, then proceed to install stiffeners in every other rib.

INSTALLING RIB STIFFENERS ON 42’ - 60’ BIN ROOFSImportant: Rib stiffeners are mandatory for 42’- 60’ bins (48’ 30 PSF roofs excluded).Each rib stiffener is composed of two or three main sections joined by splice plates. Rib stiffeners install in either every roof rib, or every second rib, depending on the roof load option selected. Refer to Figures 4.58 through 4.64 during stiffener assembly for details of rib stiffeners used for 40 psf and 60 psf roof load options (orientation of sections and splice plates, purlin bracket locations, purlin locations, and hardware useage).Begin rib stiffener installation with the right-hand rib of the inspection hatch sheet, then proceed to install stiffeners in every other rib.1. Ensure that all roof bolts are tight (ribs, sidewall, and peak).2. Refer to Figures 4.58 to 4.64 for appropriate rib stiffener diagrams.3. For each rib that requires a rib stiffener:? For the 60’ Bin: Identify the stiffener section that has a slot cut into one end, and insert that section into the rib space so that the roof angle section and eave brace fit into the slot, and rib bolts for that area fit into the bolt holes provided in the stiffener section. See Figures 4.52 for details of fit.a. Loosely fasten the stiffener section in place by adding a “double” nut to each bolt end (see Figure 4.50). b. Insert and fasten additional sections that extend toward the peak (see Figures 4.58 through 4.64 for section part numbers.c. Install splice plates and purlin brackets, using bolts and nuts in all available holes (see Figures 4.47 to 4.49). Note that purlin brackets on either side of a rib stiffener share the same bolts.Note: Only the 60’ bin designs use purlins. The 42’, 54’, and 48’ bin rib stiffeners require splice plates but do not have either purlins or purlins brackets.4. Install all additional rib stiffeners as required by the roof load option (stiffeners in every rib or stiffeners in every second rib).? 5.

INSTALLING THROAT CLIPS (15’-36’ BIN ROOFS)Note: Do not install throat clips until after all roof sheets have been installed.? For 42’-60’ bins, throat clips are installed as part of the filler cap flashing (see “Installing the Filler Cap Assembly and Flashing (42’ - 60’ Bins)” on page 111 for instructions).For all other bin diameters (15’-36’):1. Ensure that the bolts that connect the roof sheets to the filler cap throat (15’-30’ bins) or filler cap throat adaptor (33’ and 36’ bins) are installed loosely enough to fit throat clips.2. Working in a single direction (either clockwise or counter-clockwise), install the throat clips as follows: a. Insert a throat clip between the throat/throat adaptor and a roof sheet ribs, centered on a roof sheet rib, and aligned so the notch in the centre of the throat clip will fit the roof sheet bolt when inserted.b. Tighten the bolt to secure the clip tightly between the throat or throat adaptor and the roof sheet rib.c. Install one clip for each rib, clips overlapping as they are added, fully tightening each clip as it is installed.3. Verify that all throat openings are blocked by clips, and that all nuts are tight.

Ensure that the designated roof sheet has a roof sheet installed on each side of it (the sheet to the right must always be the inspection hatch sheet).2. Loosely connect rungs across the ribs of the designated roof ladder sheet with roof sheet bolts and nuts, using the existing roof sheet rib bolt holes. The placement of the ladder rungs is indicated in Tables 4.9 and 4.10.Important: Each rung bolt requires a neoprene washer (rubber side facing down) between the ladder rung and the roof rib.3. Starting at the bottom, tighten the bolts on each rung until all rungs are firmly connected. Note that specific rib bolt holes are reserved for roof rings, which act as an additional rung. See Table 4.9 and Table 4.10 for these locations.Figure 4.67 Connecting Roof Ladder RungsNEOPRENE WASHERS, RUBBER SIDE FACING DOWNHARDWARE USAGE:5/16” X 1-1/2” GRADE 8 BOLT (313-3011)5/16” SERRATED HEX FLANGED NUT (310-3022)NEOPRENE WASHER (302-4003)5/16” X 2-1/2” GRADE 8 BOLT (313-3012), FOR STIFFENED RIBS ON 60’ BINS 5/8” SPACER (202-2944), FOR USE WITH BOLT 313-3012 ABOVE ENM-18910 R0 834.
