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 nylon insert locknuts (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 nylon insert locknuts 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 nylon insert
locknuts 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 nylon insert locknuts 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.
