7.9.14.
Attach two more closure elbows to the 2 x 2 angle post in the 45-degree Angle Platform
and two to the angle post where the closure will connect with 5/16-18 x 3/4 hex cap
screws. Use the holes shown (the uppermost and the third from the top). Tighten enough
to hold the elbows in place but still allow them to rotate (FIG. 7.25).
7.9.15.
The procedure for installing the 1-1/2 diameter upper and lower tubes at the closure is
the same as described in SECTION 4.6 except the connection is between an adjustable
elbow and a closure elbow instead of between two adjustable elbows. Align the opposing
round faces, measure the upper and lower gaps, trim and install the upper and lower
tubes, then reassemble the elbows as described in SECTION 4.6 (FIG. 7.25).
7.9.16.
Install an angle cap on top of each handrail post. Use construction adhesive to bond the
cap in place (FIG. 7.26).
