Assembling Purlin Number 6
Purlin number 6 is located sixth purlin from the eave.
Before You Begin

What You Should Know
The A-frame roof rafter section consists of two roof rafters identified as the left-hand roof rafter (A) and the
right-hand roof rafter (C).
There are also two different purlin clips, a left purlin clip (E) and a right purlin clip (D). The left purlin clip
has an extra hole located in the center as compared to the right, which only has six holes where the purlin
and purlin clip are bolted together.
IMPORTANT: Do not drill additional holes in the purlin. Install the flange bolts and flange nuts as dictated
by the number of holes in the purlin.
NOTE: The seventh hole located in the center of the left purlin clip (E) is for identification purposes only.
No hardware is used in this location.
1. Attach a left purlin clip (E) and a right purlin clip (D) to the right-hand roof rafter (C), and install three
flange bolts (F) and three flange nuts (I).
2. Attach a left purlin clip (E) and a right purlin clip (D) to the left-hand roof rafter (A), and install three
flange bolts (F) and three flange nuts (I).
3. Install the purlin (H) to the right purlin clip (D) and the left purlin clip (E) located between the left-hand
roof rafter (A) and the right-hand roof rafter (C).
NOTE: Ensure that the orientation of the purlin is correct, the roof panel holes are facing up, and the
notch in the purlin is facing the right-hand roof rafter (C).
4. Install eight flange bolts (B) and eight flange nuts (G), securing the purlin to the purlin clips.
5. After all purlins are installed in the A-frame, tighten hardware to the recommended torque specifica-
tions. See
Bolt Torque Specifications, page 25
