Platform Guard Rails and Closures
Platform Closures
1. Which of the two closures is used will depend on whether the platform is a through platform, a platform turn, a 90°
platform, or a 180° turn back.
2. The 12-11/16” closure (larger closure out of the two—support to stabilizer installation) will be used on all platform
options.
It always mounts to the platform by sliding one end over a corner support and placing the other end into a
stabilizer .
3. Slide one end of the larger closure over a corner support until it rest on the top of the corner support socket. Let the
opposite end rest directly on the walking surface of the platform.
The stabilizer end (end not over a corner support) of
the closure will align vertically with the ramp guard rail. The end not over the support (stabilizer end) of the larger
closure will attach to the platform via stabilizer.
4. Mount the (1) stabilizer on the surface of the platform—solid side out— and place the closure end opposite the support
into the stabilizer.
For stabilizer install instruction see #3 above.
The larger closure (support to stabilizer), once
installed, should run from a corner support to a stabilizer, aligning vertically with existing ramp guard rail.
5. The 11-3/16” closure (smaller closure—stabilizer to stabilizer) will be used on a 90° platform and potentially on custom
systems where needed.
6. Place the smaller (stabilizer to stabilizer) closure next to the existing larger closure creating a 90° angle at the corner of
the platform where guard rails do not meet.
Use this time to determine the proper location of the stabilizers.
Remove
closure and mount (1) stabilizer to the surface of the platform next to the base of the existing larger closure upright—
solid side out. Then mount (1) stabilizer to the surface of the platform in front of the base of the existing ramp guard rail
upright—solid side out.
7. Place each end of the smaller closure into the stabilizers. The 90° closure installation has now been completed.
Additional screws, bolts, and nuts will be added later to secure rails in place.
The pre-drilled holes located in middle part of the closures are hand rail bracket mounting holes.
The pre-drilled holes located only in the top portion of the closures main vertical posts will align with
the ramp guard rail holes.
