Greenfield 304-1 Galvanized Clevis Pipe Hanger 1 Inch

Product Description

The GREENFIELD 304-1 is a galvanized steel clevis hanger designed to support 1-inch pipe in suspended piping systems. It accepts a 3/8-inch threaded rod for overhead installation and carries a rated load capacity of 250 pounds, making it suited for continuous-duty service in occupied buildings. The galvanized finish provides corrosion resistance in damp or humid environments. Plumbers, pipefitters, and mechanical contractors install this hanger on water supply lines, hydronic piping, drain lines, and HVAC refrigerant or condensate piping routed above ceilings or through mechanical rooms.

This clevis hanger fits standard 1-inch nominal pipe and is commonly used in residential and light commercial mechanical systems. Typical installations include domestic hot and cold water supply, hydronic heating and cooling distribution, compressed air lines, and low-pressure steam piping. The clevis design allows the pipe to be seated and secured without welding or special tooling, making it a standard choice for new construction and retrofit work in plumbing, HVAC, and general mechanical contracting.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter following applicable IPC or IMC requirements for pipe support spacing and hanger type. Shut off and depressurize the piping system before repositioning or replacing hangers on existing lines. Use appropriately rated threaded rod and fasteners for the structural attachment point above. Do not exceed the rated 250-pound load capacity, and verify hanger spacing against code requirements for the pipe material and fluid carried.
