Installing the 6–Hole Intermediate Purlins
Intermediate purlins must be installed to connect each A-frame roof rafter assembly together. The inter-
mediate purlins connecting each A-frame roof rafter assembly have six holes on each side to secure them
with the purlin clips.
Before You Begin
All A-frame roof rafter assemblies must be installed and secured to both the center collar and the eave
brackets.
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
