Roof Beam to Tension Coupler and Center Collar
Attach the roof beam to the tension coupler and center collar using 1/2" x 2" bolts (S-8268) and nuts
(S-3729). It is best to set the beams in assembled pairs with all purlins loosely attached. Pairs of beams
should be set by approximately quartering the roof and then evenly filling in between the quarters. The first
sets of beams that should be set are the pairs with X-bracing. See Figure 9J on Page 56 for X-bracing
assembly detail. (See Figure 9E and Figure 9F.)
