Installing the Intermediate Purlins
Intermediate purlins must be installed to connect each A-frame assembly together. The intermediate
purlins connecting each A-frame assembly have six holes on each side to secure them with the purlin
clips.
Before You Begin
All A-frame assemblies must be installed and secured to both the center collar and the eave brackets.
1. Position the intermediate purlin (132) between the purlin clips (60 and 62) located outside of each
A-frame assembly (133).
2. Install six 1/2" x 1-3/4" flange bolts (5) and 1/2" flange nuts (17) to each end of the purlin (132),
securing the intermediate purlin (132) to the purlin clips (60 and 62).
3. Tighten all the hardware to the recommended torque specifications. See
