5.9.11. Connect the Ramp Handrails at the corner turn by first trimming one leg of two 1-1/2”
diameter, 90° elbows. Trim the elbow leg which will be installed on the lower Ramp
Handrail such that the leg pointing toward the 2” x 2” angle post in the corner is 2-1/2”
(approximately) from the angle post. Trim the elbow leg which will be installed on the
upper Ramp Handrail such that the leg pointing toward the 2” x 2” angle post in the
corner is 2” (approximately) from the angle post (FIG. 5.41).
The “lower” ramp is the ramp with the upper end which ends at the platform; the
“upper” ramp is the ramp with the lower end which starts at a platform. The
1-1/2” diameter, 90° elbows are trimmed to different lengths because the
relationship of the Frame posts to the platform is not the same for “upper” and
“lower” ramps.
5.9.12. Using a metal file, smooth all sharp edges from cutting.
5.9.13. Insert 2-15/16” ring joiners in the open ends of the Ramp Handrails. Install the 90° elbow
leg trimmed for the lower Ramp Handrail to the joiner in the lower Ramp Handrail and
the 90° elbow leg trimmed for the upper Ramp Handrail to the joiner in the upper Ramp
Handrail. Orient the joiner set screws toward the underside of the ramp handrails and the
90° elbows toward the 2” x 2” angle post in the corner then tighten the joiner set screws
enough to hold the elbows in place (FIG. 5.41).
5.9.14. Clamp the Handrail Standoff to the 2” x 2” angle post in the corner at 7-3/8” from the top
of the post. Hold a 1-1/2” diameter, 90° elbow such that the middle of the bend is
centered on top of the Handrail Standoff. Rotate the 90° elbows attached to the Ramp
Handrails until they are parallel to the ends of the elbows as needed (FIG. 5.42).
There are two standoffs used at the corner turn post. The Handrail Standoff is the
larger, longer one of the two.
5.9.15. Trim all three 1-1/2” diameter, 90° elbows until the legs of the elbows align and there is a
3/4” gap between the legs. Use a ring joiner centered (approximately) between the legs
of the bends to assist in estimating where the cuts should be and use caution not to trim
too much off any one elbow leg (FIG. 5.42).
5.9.16. Using a metal file, smooth any sharp edges from cutting.
5.9.17. Assemble the three 1-1/2” diameter, 90° elbows using 2-15/16” ring joiners. Remove the
elbows from the Ramp Handrail if needed but be sure to keep track of the cut ends so
they can be reinstalled in the same orientation with respect to the handrails and each
other. Orient all joiner set screws toward the underside and tighten all joiner set screws
securely (FIG. 5.43).
5.9.18. Adjust the Handrail Standoff to contact the underside of the middle elbow then use the
holes in the standoff as a template to drill 5/16” or 11/32” holes through the 2” x 2”
angle posts (FIG. 5.43).
5.9.19. Attach the Handrail Standoff to the 2” X 2” angle posts using 5/16”-18 x 1” long button
head socket cap screws, 5/16”-18 nylon insert locknuts and 5/16” flat washers (FIG. 5.43).
5.9.20. Drive a 1/4”-14 x 3” self-drilling, self-tapping screw up through the underside of the
Handrail Standoff into the middle 1-1/2” diameter, 90° elbow. Put pressure on the elbow
until the threads engage and pull the components together (FIG. 5.43).
5.9.21. Tighten all fasteners securely including all ring joiner set screws and elbow assembly
screws if not completed previously.
