Upper Roof Panel Attachment (Continued)
(Refer to Figure 9P on Page 65.)
The upper roof panel (CRP-6341) attaches to the intermediate Z-collar (CRP-6344) using 5/16" x 1-1/4"
bolts (S-277) and flange nuts (S-3611). At the rib of the upper panel, a top roof clip (CRP-4829) should be
bolted between the panel and Z-collar. The upper part of the panel attaches to the A1 Z-collar (CRP-6367)
using 5/16" x 1-1/4" bolts (S-277) and flange nuts (S-3611). The upper roof panel (CRP-6341) should be
bolted to the B1 and C1 purlins using two (2) 5/16" x 1-1/4" bin bolt (S-275) and flange nut (S-3611).
Two (2) holes will have to be drilled through the flat of the roof panels to be bolted to the B1 and C1
Z-collars. The upper roof flashing (CRP-6926) attach to the upper most hole on the roof panel rib using
5/16" x 1-1/4" bolts (S-277) and flange nuts (S-3611). The roof panel flashing (CRP-6926) should also be
screwed to the roof panel using #10 self-drilling screw with sealing washer (S-3929). The center collar
flashing (CRP-6926) will then be sandwiched between the center collar (CRP-6349) and deck plating
(CRP-6353) of the center collar. Use 5/16" x 1-1/2" full threaded carriage bolt (S-6996) and flange nut
(S-3611) to attach the center collar, center collar flashing and deck plating. The center deck plating
(CRP-6354) sits on top of the outer deck plating and also uses 5/16" x 1-1/2" full threaded carriage bolt
(S-6996) and flange nut (S-3611) for attachment. NOTE: The center collar deck plating (CRP-6353
and CRP-6354) will not fit through the center collar from the inside of the bin. Parts must be
brought to the peak from the outside of the bin.
