Flood Barrier Store - Drilling Mounting Holes

Post should anchored to cinderblock, masonry or concrete. If your wall is of questionable quality, such as cinderblock or old bricks, you may want to purchase double expansion anchors to use in place of the included expansion bolts. You may also wish to initially drill a smaller receiver hole, into which you place the bolt, to ensure a snug fit. When installing posts on hollow walls, you will need to purchase butterfly bolts that will expand in the opening and provide a more secure hold.
