Roof Assembly for 18' through 24' Bins

NOTE: Be sure to install ladder rungs and safety steps as you assemble roof panels. When assembling

such pieces as roof ladder rungs, use 5/16" x 1" bolts with a flat washer on top of the slot and extra
neoprene washer between the roof and the piece being added. This will ensure a more protective
seal against moisture.
