Greenfield 304-112 Galvanized Clevis Hanger 1-1/2 Inch

Product Description

The GREENFIELD 304-112 is a galvanized clevis hanger designed to support 1-1/2 inch pipe in plumbing and mechanical piping systems. The hanger accepts a 3/8 inch threaded rod and carries a rated load capacity of 250 pounds, making it a dependable choice for standard residential and light commercial installations. Its compact profile — 1.05 inches tall, 2.8 inches long, and 3.8 inches wide — keeps it workable in tight ceiling and wall cavities. Galvanized construction provides corrosion resistance suitable for indoor and moderately humid environments. Plumbers and pipefitters install this type of hanger as part of suspended piping runs where consistent support spacing is required by code.

The 304-112 is suited for suspended 1-1/2 inch pipe runs in residential and commercial plumbing, HVAC piping, and mechanical systems. It is commonly used in applications where pipe must be hung from structural members using threaded rod, including drain, waste, and vent piping as well as hydronic or general-purpose mechanical lines. The compact dimensions allow installation in framed ceilings and confined mechanical spaces without interference from adjacent structure.

Installation Notes

Installation is performed by licensed plumbers or pipefitters. Shut off and depressurize the piping system before making any modifications to existing pipe runs. Hanger spacing must conform to applicable codes such as the International Plumbing Code, which specifies maximum support intervals by pipe material and size. Ensure threaded rod and fasteners are rated for the combined load of pipe, fluid, and insulation where applicable.
