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.

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.

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 (FIG. 5.13).

5.6.3.

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).
