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. Ensure that all bolts are tight and that the ramp sections are aligned parallel to one another.
FIG. 3.8
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’ in SECTION 2). The process for
installing cross braces to ramp legs and platform support tubes is the same.
