National ramp ALUMINUM SOLID, Installation Manual

Page: 94 / 138

An understanding of installing dual-rail handrails is necessary before installing the vertical picket
handrails. The primary differences between the two railings are:
ƒ
The vertical picket leg channel and footplate are two separate components, to allow
for more customization, so the leg does not interfere with the bottom rail of the vertical
picket handrails.
ƒ
While the legs are installed with 3" universal brackets (like dual-line handrails), vertical
picket handrails connect to the system using 2.5" universal brackets with 3/8" – 16 x
2.5" bolts. To join the handrails together, use through-bolts for straight connections
and corner brackets for corner connections.
In addition to the tools required to install the Liberty Series™ Ramp System, the following are also
needed:
ƒ
9/16" open end wrench (if the configuration includes an inside corner)
ƒ
7/16" socket and/or wrench
19.7.1.
Determine the required leg sizes. The top of each
platform leg should extend 2-3" above the platform’s
travel surface, while each ramp section leg should
extend 3-4" above its travel surface.
19.7.2.
Cut bottom of leg channel. Avoid cutting through
slot.
