7. Farm Roof Assembly
28 PNEG-1092 30° Bin Roof Construction
Roof Assembly for 12' 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 1-1/4" 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.
