Position the closure elbow attached to the stair top post so it is aligned with the closure elbow
attached to the platform handrail post (but do not tighten fully) then measure the distance
between the two larger round faces. The gap between the upper and lower closure elbows
should be the same but it is advisable to check both before cutting the tubes to fit (FIG.14).

Cut the 1-
1/2″ diameter round tubes to fit the gap measured in the previous step.
4.6.
Using a metal file, smooth all sharp edges from cutting the round tubes.
4.7.
Disassemble the closure elbows by removing the elbow screws and nuts but do not remove
the closure elbows halves from the platform handrail or stair top posts (FIG. 15).
4.8.
Install an elbow half into each end of the cut tube until fully engaged.
4.9.
Tighten internal set screws with a T-Handle wrench. An Allen wrench and pliers to get
additional torque can be used as an alternate (FIG. 15).
4.10.
Reassemble all elbows by replacing center insert and securing with the screw and nut then
tighten all fasteners, including the hex cap screws, securely (FIG. 15).
4.11.
Test to ensure all elbows are properly secured and attached. If needed, tighten internal set
screws to secure more rigidly.
