Carpenter Paterson 1.26 2-inch Galvanized Riser Clamp 300 Lb

Product Description

The CARPENTER PATERSON 1.26 is a 2-piece, 2-hole extension riser clamp designed to support and steady vertical pipe risers in demanding mechanical systems. Constructed from carbon steel with an electro-galvanized finish, it delivers a 300-pound load rating and withstands temperatures up to 450 degrees F. The clamp transmits pipe load to the building structure through ears on each end. It is sized for 2-inch pipe and conforms to ASME B31.1, MSS-SP-58 Type 8, AA-1192A Type 8, and BSPSS-BS3974 standards. Licensed plumbers and pipefitters install this clamp in commercial, industrial, pharmaceutical, petrochemical, and hospital piping applications.

This riser clamp is used wherever vertical pipe risers require secure support at floor penetrations or structural members. Typical installations include multi-story commercial buildings, process piping systems, and hospital mechanical rooms where code-compliant riser support is required. The clamp holds tight to the pipe and is best positioned beneath a coupling, hub, or lugs welded to the pipe to maximize load transfer. It ships in packaging quantities of 25 per box, making it practical for project-scale procurement.

Key Features

• 2-piece, 2-hole extension riser design for secure vertical pipe support
• 300-pound load rating suitable for commercial and industrial service
• Electro-galvanized carbon steel construction for corrosion resistance
• Rated for temperatures up to 450 degrees F
• Conforms to ASME B31.1, MSS-SP-58 Type 8, AA-1192A Type 8, and BSPSS-BS3974
• Ears on each end transmit load directly to the building structure

Compatibility

Designed for 2-inch pipe riser support in commercial, industrial, pharmaceutical, petrochemical, and hospital piping systems where ASME B31.1 and MSS-SP-58 Type 8 compliant support is required.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes, including ASME B31.1 and local jurisdictional requirements. Depressurize and isolate the piping system before positioning the clamp. Where possible, place the clamp directly beneath a coupling, hub, or welded lugs on the pipe to maximize load transfer to the structure. Verify that the supporting structure is rated to carry the transmitted load before final tightening.
