INSTALLING THE CONNECTOR – HR PLATFORM TO HR STAIR (MHRPSC)
4.1.
When using the
CONNECTOR – HR PLATFORM TO HR STAIR (MHRPSC)
to connect a stair top post
to a platform handrail post, closure elbows must be attached to the stair top post before the
stair handrails are attached. Locate a 5/16”-18 x 3/4” long button head socket cap screws and
install through the 5/8” diameter hole in the stair top post until the screw hits the inside wall
opposite the hole and hold in place with a T-Handle Allen wrench or hex key (FIG. 12).

4.2.
Attach a closure elbow to the outside of the stair top post using the screw installed in Step 4.1.
The elbow assembly screw should be on top and the elbow half which will be installed into the
1-
1/2″ diameter round tube must be oriented toward the platform handrail post where the
connector will attach (at approximately 90 degrees). Tighten the screw securely since it will be
inaccessible after the stair handrails are attached. Repeat Steps 4.1 & 4.2 at all locations
where the connectors will be used (FIG. 12).
NOTE: It is recommended that Steps 3.6 through 3.12 be completed before continuing with
the connector installation.
4.3.
Pass a 5/16
″-18 x 3/4″ hex cap screw through one of the two larger holes in upper portion of
the platform handrail post where the connector will attach and into the threaded end of the
closure elbow then tighten lightly. Repeat for the second larger hole in the post (FIG. 13).
