Sioux Chief 557-3 Suspension Clamp 3/4 Inch Cts

Product Description

The SIOUX CHIEF 557-3 is a 3/4-inch suspension clamp designed to support and secure copper tubing service (CTS) piping in overhead and suspended piping installations. Suspension clamps of this type hold pipe against movement caused by vibration, thermal expansion, and system pressure changes. Plumbers and pipefitters install these clamps during rough-in work to keep supply and distribution lines properly aligned and supported at code-required intervals. The 557-3 is a standard trade component used in both residential and light commercial plumbing systems wherever 3/4-inch CTS pipe requires overhead or lateral support.

This clamp is suited for suspended piping runs in mechanical rooms, crawlspaces, basements, and above-ceiling installations. It is intended for use with 3/4-inch CTS copper pipe and is sized accordingly. Plumbing contractors installing domestic water supply lines, hydronic distribution piping, or other copper tubing systems will find this clamp appropriate for standard hanger rod or structural attachment applications.

Key Features

• Sized for 3/4-inch CTS copper pipe

Compatibility

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or local plumbing code requirements for pipe support spacing. Shut off the water supply and depressurize the line before making any modifications to existing piping. Secure the clamp to approved structural members or threaded hanger rod using appropriate fasteners rated for the load. Do not overtighten the clamp hardware in a way that deforms or damages the copper tubing wall.
