5.7. TWO-LINE TURN BACK CLOSURE
5.7.1. There are two special closures available for filling the space between two ramps in a turn
back configuration. The Two-Line Turn Back Closure can be used with platforms of any
size but the 8’ x 5’ Vertical Picket Closure can only be used with the 8’ x 5’ platform. Turn
back closures can also be created using the methods described in the proceeding sections
by attaching the components to platform posts between the ramps rather than directly
from ramp handrail to ramp handrail.
5.7.2. Regardless of style, first connect the ramp handrails by installing adjustable elbows in the
ramp handrails. Loosen the elbow assembly screws and position the adjustable elbows so
they are aligned with the elbow on the opposite side (but do not tighten), and then
measure the distance between the two larger round faces (FIG. 5.18).
5.7.3. Cut a 1-1/2″ diameter round tube to the measured gap (FIG. 5.18).
5.7.4. Using a metal file, smooth all sharp edges from cutting the round tubes.
5.7.5. Disassemble the adjustable elbows by removing the screw and nut (FIG. 5.4).
5.7.6. Install an elbow half into each end of the cut tube (FIG. 5.4).
5.7.7. Tighten the internal set screw using an Allen wrench or similar tool (FIG. 5.4).
5.7.8. Reassemble the elbows by replacing center insert and securing with the screw and nut
(FIG. 5.5).
5.7.9. Test to ensure all elbows are properly secured and attached. If needed, tighten internal
set screw in the closure elbow to secure more rigidly.
5.7.10. Orient the platform closure 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 4” above the platform deck. Clamp in place temporarily if
needed (FIG 5.19).
5.7.11. 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 (FIG. 5.19).
Tighten securely but use caution not to overtighten and strip the threads.
