Carpenter Paterson 126-3 Riser Pipe Clamp 3 Inch Carbon Steel

Product Description

The CARPENTER PATERSON 126-3 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 transmit load forces to the supporting structure through the ears on each end. Rated at 500 pounds load capacity, it meets ASME B31.1, MSS-SP-58 Type 8, AA-1192A Type 8, and BSPSS-BS3974 standards. Plumbers and pipefitters install this clamp as part of vertical riser support assemblies in a wide range of facility types.

The 126-3 is suited for commercial, industrial, pharmaceutical, petrochemical, and hospital piping installations where reliable vertical pipe support is required. It fits 3-inch pipe and has an overall length of 12 inches. When possible, the clamp should be placed just below a coupling, hub, or lugs welded to the pipe to optimize load transfer and prevent pipe movement. Packaged 20 units per box, it is well-suited for both single-installation service calls and larger multi-riser projects.

Compatibility

Designed as an OEM-style riser clamp for 3-inch pipe in commercial, industrial, pharmaceutical, petrochemical, and hospital piping systems where ASME B31.1 and MSS-SP-58 Type 8 compliant support is specified.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Isolate and depressurize the pipe system before installing or repositioning any riser clamp. Position the clamp below a coupling, hub, or welded lug when the installation layout permits to maximize load transfer to the structure. Verify that fasteners are properly tightened and that the clamp ears are fully bearing on the supporting structure before returning the system to service.
