1. Install the Support Framing and Bracket

NOTE: These instructions show one possible ceiling conﬁguration.

Adapt to ﬁt your application.

Using 2x4s, construct support framing to mount the bracket. The

face of each 2x4 should be installed ﬂush with the face of the

ceiling joists.

Ensure that each corner of the bracket can be mounted to the

support framing with at least 2 screws.

CAUTION: Risk of personal injury. If the bracket is not

securely held in place during installation, the product may

fall causing personal injury.

Align the bracket so that its edges are parallel to the shower

walls. Orient the inlet pipe hole for the easiest connection to the

water supply.

Install the bracket with at least 2 #8 1-1/2″screws per corner.

Screws may be installed in any two of the four holes per corner.
