The ASC Engineered Solutions 500361100 is a galvanized steel riser clamp designed to support vertical pipe runs at floor penetrations and structural members. Built for iron pipe size (IPS) pipe, this 4-inch clamp bears the load of a riser at each floor level, keeping the pipe plumb and transferring weight to the building structure. The galvanized finish provides corrosion resistance in wet or exposed mechanical spaces. At 2.24 pounds, it is sized for straightforward handling during installation on standard commercial and residential plumbing systems.
This riser clamp is used in plumbing and mechanical piping systems where vertical pipe must be supported at each story. Typical applications include multi-story residential buildings, commercial mechanical rooms, and industrial facilities where IPS-sized pipe rises through floor slabs or framed openings. It is installed by licensed plumbers and pipefitters working on water supply, drain, or process piping systems requiring positive vertical load support.
Designed as an OEM-style riser support for 4-inch IPS pipe in vertical plumbing and mechanical piping installations.
Riser clamps are installed by licensed plumbers or pipefitters in accordance with applicable plumbing codes such as the IPC and local amendments. Shut off and depressurize the pipe system before positioning the clamp at the floor or structural support point. The clamp should bear fully on the support structure with fasteners properly tightened to prevent pipe movement. Do not use this clamp as the sole means of lateral restraint in seismic zones without additional bracing per code.
