Holdrite 731 Stub-out Clamp 1/2 Inch Cts Pex Cpvc

Product Description

The HOLDRITE 731 is a stub-out clamp bracket designed to support 1/2-inch CTS tubing in residential and light commercial plumbing rough-in applications. It secures 1/2-inch PEX tubing, CPVC, and copper pipe at wall stub-out locations, holding the tubing firmly in place during and after installation. The 731 is intended for use exclusively with HOLDRITE SB3 or SB4 stub-out brackets, making it a dedicated component within that bracket system. Licensed plumbers and rough-in crews install this clamp during the framing stage before drywall is applied.

This clamp is suited for residential new construction and remodel projects where 1/2-inch CTS supply lines terminate at fixture stub-out locations. Common applications include lavatory, kitchen, and utility rough-in points where PEX, CPVC, or copper supply lines need to be held securely in the wall cavity. Because it is engineered specifically for the SB3 and SB4 bracket platform, it provides a consistent, repeatable stub-out position that simplifies trim-out and fixture connection.

Key Features

• Supports 1/2-inch CTS tubing including PEX, CPVC, and copper
• Compatible with HOLDRITE SB3 and SB4 stub-out brackets
• Secures tubing at wall stub-out locations during rough-in
• Designed for consistent, repeatable stub-out positioning

Compatibility

The HOLDRITE 731 is designed for use with HOLDRITE SB3 or SB4 stub-out brackets only. It supports 1/2-inch CTS PEX tubing, CPVC, and copper pipe.

Installation Notes

Installation is performed by a licensed plumber during the rough-in phase, prior to wall finish. Power or water supply does not need to be shut off for bracket installation, but all supply lines should be depressurized and drained before any tubing work is performed. The 731 clamp must be used with a compatible SB3 or SB4 bracket and should not be used as a standalone pipe support. Follow local plumbing codes and IPC guidelines for stub-out placement and support spacing.
