Ring Instructions

Be sure to install ladder rungs and safety steps as you assemble roof panels.

(See Figure 12A.)

At this

point you will have completed assembly of the roof. Do not tighten bolts yet. Optional equipment and
accessories should now be installed.

NOTE: 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.

IMPORTANT: Maximum weight to be supported and/or suspended from the roof is to be 6000 pounds

for 18' through 48' (non-trussed) ONLY.

WARNING

DO NOT OVERFILL BIN. Stored grain, although heaped in the center, should
be no higher than the roof eaves at the outer edge. Filling the bin above this point
creates excessive internal pressure and may cause swelling and eventual failure of
the roof.
