Installing the Intermediate Purlins
Intermediate purlins must be installed to connect each A-frame roof rafter assembly together.
Before You Begin
All A-frame roof rafter assemblies must be installed and secured to both the center collar and the eave
brackets.
What You Should Know
IMPORTANT:
The A-frames may have X-braces attached to the purlins. Before installing intermediate
purlins, make sure to loosen and remove the flange bolt and the flange nut securing the X-
braces with lower purlin clips and the rafters in the adjacent A-frames (if available).
1. Install the intermediate purlin (A) to the purlin clips (B and D) located outside of each A-frame roof
rafter assembly (E).
2. Install six flange bolts (C) and six flange nuts (F) to each end of the purlin (A) securing the intermedi-
ate purlin to the purlin clips.
3. Tighten the hardware to the recommended torque specifications. See
.
