INSTALLATION
Determine stub out height. Screw bent ends of each bracket inside stud
cavity on one side. Slide the metal bend support across brackets to desired
stub out location. Using pliers, pinch the rear lip of the metal bend support
in each corner of faceplate to prevent lateral movement on the brackets.
Spreading the loose bracket ends apart, anchor the loose ends of the
brackets inside opposite side of stud cavity starting with the lower bracket
to keep installation level. Install flexible ½" CTS tubing in metal bend
support. Bend support swivels to accommodate tubing coming from any
direction. For the most rigid installation, spread loose bracket ends as far
apart as possible before anchoring to stud.
