Rotate or disassemble as needed to install the base weldment, and then re-level the
swaged 1-1/2” diameter tube bend and tighten 2-15/16” ring joiner set screw securely
(FIG. 7.2).
7.1.6.
Ensure the swaged end of the 1-1/2” diameter tube bend is inserted as far as possible
into ramp handrail, and then install two 1/4” x 1” long self-drilling, self-tapping pan
head Phillips screws in the handrail in the same manner described in step 6.3.2.5.
7.1.7.
Orient the 4” x 4” x 1/4” thick mounting base away from the expected path of travel

one wall of both the trimmed 38-3/4” long, 90
0
bend and the 1.315” x 12” long stub
tube at 90° apart (FIG. 7.2). Orient the pilot holes such that the screws installed in the

Install two 1/4” x 1” long self-drilling, self-tapping pan head Phillips screws through
the bottom of the trimmed 38-3/4” long, 90
