5.3.8. Referencing FIG. 5.6, locate a closure bracket. Remove the 5/16″-18 x 2-1/4″ hex bolt and
5/16” flat washer attaching the midrail of the Frame, then reinstall the bolt and washer
through the slot in the short leg of the bracket, the Frame post, and back into the
threaded insert in the midrail. Orient the bracket so the long leg is on the same side as,
and parallel to, the 2” x 2” angle post, then tighten lightly (enough to hold the bracket
against the post but still allow it to rotate).
5.3.9. Measure the gap between the long leg of the closure bracket and the 2” x 2” angle post
(FIG. 5.7).
5.3.10. Cut the 1.5” x 2” closure midrail to the measured length less 1/8” to account for the
threaded inserts which will be installed after cutting.
5.3.11. Using a metal file, smooth any sharp edges from cutting.
