Carpenter Paterson 0.126 Galvanized Riser Clamp 3 in

Product Description

The CARPENTER PATERSON 0.126 is a 2-piece, 2-hole extension riser clamp designed to support and steady vertical pipe risers in commercial and industrial piping systems. Constructed from carbon steel with an electro-galvanized finish, it fits 3-inch pipe and carries a load rating of 500 pounds. The clamp transmits load to the supporting structure through ears on each end. It is engineered to hold tight to the pipe and is rated for temperatures up to 450 degrees F. Licensed pipefitters and plumbers install this clamp as part of pipe hanger and support assemblies.

This riser clamp is suited for commercial, industrial, pharmaceutical, petrochemical, and hospital piping applications. It meets ASME B31.1, MSS-SP-58 Type 8, AA-1192A Type 8, and BSPSS-BS3974 standards. When placement is possible, the clamp should be positioned under a coupling, hub, or lugs welded to the pipe to maximize load transfer and structural integrity. It is sold in packaging quantities of 25 per box, making it practical for contractors managing multiple riser support points on a project.

Compatibility

Designed for use with 3-inch pipe risers in commercial, industrial, pharmaceutical, petrochemical, and hospital piping systems where vertical pipe support is required per ASME B31.1 and MSS-SP-58 Type 8 standards.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical and plumbing codes, including ASME B31.1 and local jurisdictional requirements. Shut off and depressurize the piping system before installing or repositioning any pipe support hardware. Where feasible, position the clamp directly below a coupling, hub, or welded lugs on the pipe to ensure proper load transfer to the structure. Verify that the supporting structure is rated to handle the transmitted load before completing the installation.
