5.5. TWO-LINE CLOSURE LOWER RAIL
5.5.1. Locate a platform closure bracket. Remove the 5/16″-18 x 2-1/4″ hex bolt and 5/16” flat
washer attaching the lower Two-Line ramp handrail then reinstall bolt and washer
through the slot in the short leg of the bracket, the ramp handrail post and into the
threaded insert in the lower rail. Orient the bracket so the long leg is on the same side as
and parallel to the platform post then tighten lightly (enough to hold the bracket against
the post but still allow it to rotate) (FIG. 5.10).
5.5.2. Measure the gap between the long leg of the closure bracket and the platform post (FIG.
5.11).

5.5.3. Cut the 1 1/2″ diameter round tube
to the measured gap length less
1/8” to account for the threaded
inserts which will be installed after
cutting (FIG. 5.12).
5.5.4. Using a metal file, smooth all sharp
edges from cutting the round tube.
5.5.5. Install 5/16”-18 round threaded
inserts into both ends of the cut
tube. Use a rubber mallet or similar
tool to fully seat the threaded
inserts (FIG. 5.12).
5.5.6. Install 5/16″-18 x 1″ hex bolts
through a 5/16” flat washers and
the slot in the long leg of the
closure bracket and the third hole
from the top of the platform post
into the threaded inserts installed
in the previous step then tighten all
fasteners securely (FIG. 5.12).
