within the stud cavity.

MATERIALS

metal bend support: 18 gauge electroplated galvanized steel
screw: #6 × 1" zinc-plated coarse thread

SAFE WORKING LOAD*

25 lbs. at 140°F

*Safe working load = ½ failure

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.
