Greenfield 300-3 Swivel Ring Pipe Hanger 3 Inches Galvanized

Product Description

The GREENFIELD 300-3 is an adjustable swivel ring pipe hanger designed for secure vertical suspension of 3-inch pipe in mechanical, plumbing, and piping system installations. Part of the FIG 300 series, this loop-style hanger provides precise elevation alignment and even load distribution across suspended runs. Constructed from galvanized steel, it delivers corrosion resistance suited for commercial and industrial environments. The adjustable design allows the installer to fine-tune pipe elevation after initial mounting, accommodating field conditions without additional hardware. Working load capacity is rated at 600 pounds, making it appropriate for heavier pipe runs and fluid-filled systems.

This hanger is used in commercial and industrial piping installations where vertical pipe suspension is required. Typical applications include HVAC hydronic piping, process plumbing, fire protection supply lines, and general mechanical piping where galvanized hardware meets corrosion-resistance requirements. The swivel feature allows angular adjustment to accommodate non-plumb rod installations, which is common in retrofit and renovation scenarios. Licensed plumbing and mechanical contractors are the primary installers of this product in above-ceiling and exposed-structure applications.

Installation Notes

Installation is performed by licensed plumbers or mechanical contractors in accordance with applicable plumbing and mechanical codes, including IPC and IFGC requirements for pipe support spacing and hanger type. De-pressurize and isolate any active piping system before modifying existing hangers or support assemblies. Threaded rod sizing and anchor point capacity must be verified to support the combined load of the pipe, fluid, and hanger before installation. Do not exceed the rated working load capacity of 600 pounds per hanger point.
