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. Page 21
