5.6. VERTICAL PICKET CLOSURE
5.6.1. Vertical Picket closures are specific to the platform size (4’, 5’ and 6’) and come in
two pieces which allow the ramp to be mounted to one side or be centered on a
platform side. If the ramp is to be centered on a platform additional components are
needed. The additional components will come with the closure if specified at the
time of order but the closure can be converted to allow the ramp to be centered in
the field by ordering a second set of hardware. Locate the correct Vertical Picket
closure for the platform.
5.6.2. Bolt the two Vertical Picket closure sections together using 5/16”-18 x 3/4” long hex
bolts, 5/16” flat washers, and 5/16”-18 nuts (as shown in FIG 5.13). Then, Insert 1-
1/4” square tube plugs in the open ends of the top and bottom rails on one side. If
the ramp will be centered, do not assemble. Insert 1-1/4” square tube plugs in all
open ends which do not attach to a platform post.
The 4’ closure includes angles (rather than channels) on one side to allow access
to the assembly fasteners. Always bolt the 4’ closure together using the side
with the angles and attach the side with the channel to the platform post (FIG.
5.14).

5.6.3. Attach the Vertical Picket closure to the platform handrail post using 5/16”-18 x 3/4”
long hex bolts, 5/16” flat washers and 5/16”-18 nuts as shown (FIG. 5.15). When
centering the ramp attach one section (unassembled) to the platform posts on both
sides of the ramp and secure in the same manner.
5.6.4. Locate the platform closure brackets and attach the short leg of the brackets to the
ramp post with 5/16″-18 x 2-1/4″ hex bolts, 5/16” flat washers and 5/16″-18 nuts
using the holes (FIG. 5.16). Orient the bracket so the long leg is on the same side as
and parallel to the Vertical Picket closure then tighten lightly (enough to hold the
bracket against the post but still allow it to rotate).
5.6.5. Install a 5/16″-18 x 1″ hex bolt through a 5/16” flat washer, the slot in the long leg of
the closure bracket and the holes in the Vertical Picket closure. Use 5/16” flat
washers and 5/16″-18 nuts to attach then tighten all fasteners securely (FIG. 5.17).
5.6.6. Repeat steps 5.6.4 & 5.6.5 on the opposite side when centering the ramp.
