(4) 1/2 in x 1‑1/2 in bolts, (8) 1/2 in washers and 4
nylon locking nuts.
4. Repeat the bracket installation on the adjacent

the strut using (4) 1/2 in x 3 in bolts with (8) 1/2 in
washers and 4 nylon lock nuts.

plates accommodate both angled and skewed beams.

b. Attach the enclosure brackets (H) to the opposing
face of the extension tube. Use (2) 1/2 in x 4.5 in
bolts, washers and nylon lock nuts.
8. If no extension tube is present, attach the enclosure
bracket to the purlin bracket using (4) 1/2 in x 1.5 in
bolts, washers and nylon lock nuts.
9. Tighten all nylon lock nuts.
10. After enclosure is in place, install safety cable:
a. Slide the safety cable clamp (I1) onto the safety
cable (I2).

(when present), around the purlin and secure with
the safety cable clamp.
