HORIZONTAL PICKET CLOSURE
5.6.7.
The Horizontal Picket closure includes a special bracket which is attached to the ramp
handrail post. If the ramp handrail has Horizontal or Vertical Pickets, remove the
5/16″
-18 x 2-
1/4″
hex bolt and 5/16” flat washer attaching the upper and lower rail
then reinstall through the slots in the horizontal picket closure bracket as shown in
FIG 5.18. If the ramp handrail is a Two-Line or Single-
Line handrail, use 5/16″
-18 nuts
to attack the bracket in the same manner (FIG 5.15). Orient the bracket toward the
platform post and align the holes in the bracket with the holes in the platform post as
closely as possible then tighten the fasteners lightly (enough to hold the bracket in
place but still allow movement). If the ramp is centered a second Horizontal Picket
closure is needed and is installed in the same manner described below.
5.6.8.
Measure the gap between the horizontal picket closure bracket and the platform
post (FIG. 5.19).
5.6.9.
Cut a 1 1/2″ diamet
er round tubes and the 1-1/2” x 2” curb to the measured gap
length less 1/8” to account for the threaded inserts which will be installed after
cutting (FIG. 5.14).
5.6.10.
Using a metal file, smooth all sharp edges from cutting the round tubes and curb.
5.6.11.
Install 5/16”-18 round threaded inserts into both ends of the cut tube and curb. Use a
rubber mallet or similar tool to fully seat the threaded inserts (FIG. 5.19).
