Greenfield 820-1/2 Ductile Iron Pipe Ceiling Flange 1/2 in

Product Description

The GREENFIELD 820-1/2 is a ductile iron threaded companion pipe ceiling flange designed for securing 1/2-inch pipe or rod assemblies to ceiling or overhead structural surfaces. Rated to 180 pounds load capacity and 150 psi pressure, this flange is built for mechanical and HVAC pipe support applications where reliable overhead attachment is required. The plain iron finish suits standard interior environments. At 2.62 inches overall length and a 1-3/4-inch hole center-to-center spacing, it mounts with 12 screws for a stable, multi-point connection. Licensed pipefitters, plumbers, and HVAC mechanics install this type of hardware during new construction and retrofit work.

This ceiling flange is suited for residential and light commercial piping systems where overhead pipe support or hanger rod termination is required. It threads directly onto 1/2-inch iron pipe or accepts a 1/2-inch hanger rod, making it a practical solution for suspending duct hangers, conduit supports, and similar mechanical systems from concrete, wood joist, or steel ceiling structures. It is commonly used in HVAC, plumbing, and general mechanical rough-in work.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC mechanic. Shut off any pressurized systems in the work area before attaching or removing pipe support hardware. Ensure the mounting surface can support the full rated load before fastening. Follow local building codes and applicable mechanical code requirements for pipe support spacing and fastener selection.
