Lower Flange Brace Instructions
. NOTE: The purlins and Z-collars are hidden for clarity reasons.
The lower flange brace consists of two (2) brace clips (CRP-6450) attached to the bottom of every roof
beam. The brace clips (CRP-6450) are attached using 1/2" x 1-1/2" bolts (S-3728) and 1/2" nut (S-3729).
(See detail - lower flange ring
for attachment detail.) The support ring pipe
(CRP-6382) then slides through the support ring clips. There are a total of fifteen (15) support ring pipes
(CRP-6382). Each support ring pipe spans three (3) bays. The pipe should be started halfway between
two (2) roof beams and end in the middle of two (2) roof beams, three (3) bays over. Each pipe should
be tight against the next pipe. The final support pipe placed under the roof beam will have to be cut to fit.
At each splice, wind ring couplers (SWS-4212) should be assembled to hold the pipes together. Wind ring
couplers are assembled using six (6) 3/8" x 1-1/2" flange bolts (S-7928) and flange nut (S-9373).
