Carpenter Paterson 0.0126 Galvanized Riser Clamp 4 in

Product Description

The CARPENTER PATERSON 0.0126 is a 2-piece, 2-hole extension riser clamp designed to support and steady vertical pipe risers in demanding mechanical systems. Built from carbon steel with an electro-galvanized finish, it is engineered to grip the pipe firmly and transfer load to the surrounding structure through the ears on each end. Rated for loads up to 750 pounds and temperatures up to 450 degrees F, this clamp is sized for 4-inch pipe and meets ASME B31.1, MSS-SP-58 Type 8, AA-1192A Type 8, and BSPSS-BS3974 standards. It is installed by licensed plumbers and pipefitters on commercial and industrial piping systems.

This riser clamp is suited for commercial, industrial, pharmaceutical, petrochemical, and hospital piping installations where vertical pipe risers require positive load-bearing support. When installation conditions allow, the clamp should be positioned just below a coupling, hub, or lugs welded to the pipe to maximize structural engagement and load transfer. The 2-bolt fastening configuration and 13.625-inch overall length accommodate standard 4-inch pipe schedules in riser applications.

Compatibility

Designed as an OEM-style riser clamp for 4-inch vertical pipe riser applications in commercial and industrial piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including ASME B31.1 where required. De-pressurize and isolate the piping system before positioning or adjusting the clamp. Where possible, place the clamp directly beneath a coupling, hub, or welded lug to ensure proper load transfer to the building structure. Verify that the supporting structure can handle the transmitted load before final tightening.
