2. Using the support arms as guides, position the vertical support tube (234069) such that it attaches to the other ends
of the support arms using the support arm clips, bridges the eave of the roof panel, and aligns alongside the wall
sheet. Using the holes in the vertical support tube as a guide, drill 3/8” holes through the crest of the mating wall
sheet corrugations and attach using 3/8” x 2 ½” bolts. Putting the sealing washer on the inside insures a water tight
seal. Attach the plastic cap (234559) to the vertical support tube.
