5.8. PICKETED GUARD TURN BACK CLOSURE
There are four special closures available for filling the space between two ramps in a turn back
configuration: Two-Line Rail for a 5’ platform side; Picketed Guard for a 5’ platform side; Two-
Line Rail for a 6’ platform side; Picketed Guard for a 6’ platform side. Turn back closures for a 7’
platform side are uncommon and are ordered as a custom closure.
5.8.1. Install two 2” x 2” turn back angle posts into the open platform corner pockets with
rounded end oriented upward, first. Align the bottom of the posts with bottom of the
corner pockets, then tighten set screws in the corner pockets to hold the posts in place
(FIG. 5.28). See
SECTION
4.6 and FIG. 4.11 for additional details on set screw locations.
5.8.2. Attach Picketed Guard Closures to the 2” X 2” turn back angle posts using 5/16”-18 x 1”
long hex bolts and 5/16” flat washers to attach the upper rail. To attach lower rail, use
5/16”-18 x 1” long hex bolts (do not use a flat washer at this location)(FIG. 5.29).
Picketed Guard Closures are symmetric so what becomes the “upper” or “lower”
rail depends on how the closure is positioned at installation.
