This crowding tub has evolved from several years use in the field. The tub can be set-up in four different configurations with right or left side entry. Our 4' access door is standard and makes loading out of the tub into a stock trailer or ramp for liners a snap. It's easy to see that the tub design came from cattlemen as it is up off the ground. This feature eliminates having to get into the tub with a pick and shovel. It allows for build-up of frozen materials in the winter, without interfering with the tub's operation. Our catwalk insures that using the tub is a one man operation. Silicone caulking on all sheeting and belting on the spring loaded swing gate latch keeps the noise level to a minimum.
