7. OPTIONAL EQUIPMENT
7.1. RAMP SUPPORT TOP
The PRST (RAMP SUPPORT TOP) provides supplemental support at the upper (or lower) end of the
ramp. When used, the support top replaces the PRHBPR (RAMP HANDRAIL END BRACKET PAIR).
7.1.1. Attach top support brackets with two 5/16"-18 x 1-1/2" hex bolts and each 5/16" flat
washers (FIG. 7.1).
There is a “left” and “right” top support bracket but they can be installed on either
side of the ramp depending on whether they are used at the upper or lower end of
the ramp or ramp run. The two longer studs must be oriented toward the end of
the ramp regardless of the side where they are being installed.
7.1.2. If used with a transition plate (upper or lower), the following steps are completed after
the ramp is resting on a supporting surface and transition plate is installed.
7.1.3. Locate the appropriate PRLxxPR (RAMP LEG PAIR where xx denotes the leg length) for the
location. Insert the leg into a foot. Make sure the leg is fully engaged in the foot and the
foot will be oriented so it extends under the ramp once installed (FIG. 7.2). Tighten the
thumb screw on each foot securely.
If installing on soft soil it may be necessary to set the foot on a concrete pad.
7.1.4. Place the slot in the ramp leg over the two shorter studs of the top support bracket,
install 5/16”-18 nylon insert locknuts and 5/16” flat washers on each stud adjust height if
needed and tighten locknuts. Repeat on the opposite side.
7.1.5. Insert plugs into tops of the ramp legs.
7.1.6. Refer to previous sections for anchoring upper and lower transitions.
