- 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.

3.3.10. Adjust the ramp legs one at a time.
3.3.11. Raise the ramp sections (at the center saddle bracket) to take any sag out of the ramp
run, then tighten the two locknuts in each leg.
ADA guidelines call for a maximum slope of 1:12 (approximately 5-degrees) and this is
the ideal slope for the system. However, the ramps can be installed from 1:14 to 1:8
(approximately 4- to 7-degrees). Do not attempt to install the ramps outside this
range.
If the ramp is installed at the maximum angle (approximately 7-degrees), longer legs
may be required.
Adjusting sections can be accomplished by having someone sight down the ramp
while another person adjusts the ramp height.
Ensure that the ramp sections are parallel to each other. If they are not, it may be
difficult to install the handrails (FIG. 3.8).
3.3.12. Insert a plug into the top of each leg (FIG. 3.6).
3.3.13. Ensure that all bolts are tight and that the ramp sections are aligned parallel to one another.

3.4. INSTALL UNIVERSAL ANGLE BRACE - RAMPS
If the walking surface is over 36″ high, a PUAB (UNIVERSAL ANGLE BRACE) must be installed under the
ramp (FIG. 3.9).
3.4.1. The opposite end of the angle brace is attached to the bottom of the ramp (near the
center of the tread at the end of the ramp) using a 1/4″ x 1” long self-drilling screw.
Ensure that all angle braces are secured before using the ramp.
3.4.2. Walking surfaces over 72″ or higher require UNIVERSAL CROSS BRACES in addition to the
angle braces (see ‘INSTALL UNIVERSAL CROSS BRACE’). The process for installing cross
braces to ramp legs and platform support tubes is the same.
