Carpenter Paterson 126-12 Riser Clamp 1/2 Inch Black Carbon Steel

Product Description

The CARPENTER PATERSON 126-12 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 a black finish, it is engineered to grip the pipe firmly and transfer the load to the surrounding structure through the ears on each end. The clamp carries a rated load capacity of 220 pounds and is sized for 1/2-inch pipe. When conditions allow, the clamp should be positioned directly beneath a coupling, hub, or lugs welded to the pipe for maximum load transfer efficiency. Licensed plumbers and pipefitters install this type of hardware in mechanical rooms, risers, and vertical pipe runs.

The 126-12 is suited for commercial, industrial, pharmaceutical, petrochemical, and hospital piping installations. It meets ASME B31.1, MSS-SP-58 Type 8, AA-1192A Type 8, and BSPSS-BS3974 standards, making it appropriate for code-compliant pipe support work across a wide range of regulated environments. The clamp ships in a packaging quantity of 25 per box, which suits contractors stocking risers across multi-story or multi-zone systems.

Compatibility

Designed as an OEM-style riser clamp for 1/2-inch vertical pipe runs in commercial, industrial, pharmaceutical, petrochemical, and hospital piping systems requiring ASME B31.1 and MSS-SP-58 Type 8 compliant support hardware.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Isolate the system and relieve any pressure before installing or repositioning clamps on live piping. Where possible, place the clamp directly below a coupling, hub, or pipe lug to maximize load transfer to the structure. Ensure the mounting surface and fasteners are rated for the intended load before torquing the two bolts.
