Chapter 7: Roof Assembly
Assembling the Temperature Cable Bracket
The temperature cable brackets are installed to the roof rafters and support the temperature cables.
Before You Begin
Determine the correct location of the temperature cable brackets within the structure of the A-frame
Assembly. See
About Temperature Cable Brackets and A-Frame Assemblies, page 84 .
What You Should Know
The A-frame assembly consists of two roof rafters, purlin clips, purlins and possibly X-bracing. The temper-
ature cable brackets should be installed when the A-frames are assembled.
NOTE: The temperature cable bracket must be installed at specific locations, see About Temperature
Cable Brackets and A-Frame Assemblies, page 84 .
1. Attach a right purlin clip (C), a left purlin clip (D) and a temperature cable bracket (B) to the roof rafter
(A), and install two flange bolts (E) and two flange nuts (F).
NOTE: If no X-bracing is installed, install three flange bolts (E) and three flange nuts (F).
2. After all purlins and X-bracing are installed in the A-frame, tighten all hardware to the recommended
torque specifications. See Bolt Torque Specifications, page 28 .
