Upper Roof Panel Attachment (Continued)
(Refer to Figure 9P on Page 62.)
The upper roof panel (CRP-6341) attaches to the intermediate Z-collar (CRP-6344) using 5/16" x 1" flange
bolts (S-10260) and flange nuts (S-10268). 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" flange bolts (S-10260) and flange nuts (S-10268). The upper roof panel
(CRP-6341) should be bolted to the B1, B2 and C1 purlins using two (2) 5/16" x 1" flange bolts (S-10260)
and flange nut (S-10268). Two (2) holes will have to be drilled through the flat of the roof panels to be
bolted to the B1, B2 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" flange bolts (S-10260) and flange nuts (S-10268). 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-10268) 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-10268) 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.
