Installing the 4–Hole Intermediate Purlins
Intermediate purlins must be installed to connect each A-frame roof rafter assembly together. 4-hole inter-
mediate purlins have only four 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).
