FIG. 5.24
5.8.16. If installing a Two-Line Turn Back Closure, a second 1-1/2” diameter round tube is
installed in the same manner as the curb at the bottom. Orient the brackets so the long
leg is on the same side as and parallel to the bracket on the opposite side, the short leg is
aligned with the ramp handrail post, and the tops of the brackets are 20-1/2” above the
tops of the brackets attaching the curb. Clamp in place temporarily if needed (FIG. 5.25).
5.8.17. Drive 5/16”-18 x 1-1/4” self-drilling, self-tapping hex washer head screws, centered in the
slot, through the platform closure brackets and into the ramp handrail posts. Tighten
securely but use caution not to overtighten and strip the threads.
5.8.18. Measure the gap between the long leg of the closure brackets, trim the 1-1/2” diameter
tube to the measured gap length less 1/8”, and install 5/16”-18 round threaded inserts in
the ends of the tube as described previously (FIG. 5.25).
5.8.19. Attach the 1-1/2” dia. tube with 5/16”-18 round threaded inserts installed to the brackets
using 5/16”-18 x 1” hex bolts through 5/16” flat washers and tighten securely (FIG. 5.25).
5.8.20. Attach 1-1/2” dia. tube with 5/16”-18 round threaded inserts installed to the brackets
using 5/16”-18 x 1” hex bolts through 5/16” flat washers and tighten securely (FIG. 5.25).
5.8.21. The 8’ x 5’ Vertical Picket Closure can only be used with the 8’ x 5’ platform. Set the base
of the 8’ x 5’ Vertical Picket Closure on the platform side rail then drive 5/16”-18 x 1-1/4”
self-drilling, self-tapping hex washer head screws, centered in the slots of the closure
brackets, through the brackets and into the ramp handrail posts. Tighten securely but use
caution not to overtighten and strip the threads.
5.8.22. Attach the base of the 8’ x 5’ Vertical Picket Closure to the platform side rail using four
1/4” x 1” long self-drilling screws (FIG. 5.26).
