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 PSLxxPR (SUPPORT 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 set screws 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 set
screws 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 a 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 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 (FIG. 3.7). Repeat on the opposite side.
