- 5.1. If installing a closure on a platform in the “straight” configuration, the 2” x 2” angle post will already be in place; skip to step 5.4
- 5.2. If installing on a platform in the ‘turn’ configuration, install the 2” x 2” angle post not attached to a platform handrail in the open platform corner pocket. Align the bottom of the post with the bottom of the corner pocket and tighten the set ...
- 5.3. Install an angle cap on top of the handrail post (FIG. 5.1). Use construction adhesive to bond the cap in place.
- 5.4. First install the top rail, the rail connecting the ramp handrail to the platform post.

3.3.3. Level the Support Leg Bracket using a bubble level or similar tool, then torque the 5/16”-
18 nylon insert locknuts to 20 ft.-lbs.
3.3.4. Locate the appropriate PRLxxPR (RAMP LEG PAIR where “xx” denotes the leg length) for
the location. Place a foot under the Support Leg Bracket with the foot extending under
the ramp, then insert a 1-1/2” square Support Leg through the Support Leg Bracket into
the foot. Loosen the 3/8”-16 headless socket setscrews and the foot thumb screw if
needed to fully engage the Support Leg in the foot (FIG. 3.6).
If installing on soft soil it may be necessary to set the foot on a concrete pad.
3.3.5. After the Support Leg is fully engaged in the foot, tighten the 3/8”-16 headless socket
setscrews to 15 ft.-lbs. (FIG 3.6).
Do not attempt to walk on the ramps until all Support Leg set screws have been
tightened as specified.
3.3.6. Tighten the foot thumb screw and insert 1-1/2” square plug into the top of the Support
Leg (FIG. 3.6).
3.3.7. Repeat the above procedure at all locations where ramps connect and also at the ends of
a ramp or ramp run if a PRST – Ramp Support Top is used.
In situations where the lower end of a ramp or ramp run is too close to the ground to
install normal feet and feet are needed due to ground or other conditions, low profile
feet (part no. PRLWALP) are available (FIG 3.7).
3.3.8. Remove the 5/16”-18 nylon insert locknuts and 5/16” flat washers attaching the ramp
handrail post (if already installed).
3.3.9. Position the low profile foot so the foot is oriented under the ramp and the channel leg
wraps around the ramp post. Reinstall the locknuts and flat washers, adjust height as
described below, then tighten fasteners securely. Repeat on the opposite side (FIG. 3.7).
