Greenfield 825-12 Junior Top Beam Clamp 1/2 in Rod

Product Description

The GREENFIELD 825-12 is a junior top beam clamp designed for suspending threaded rod from structural steel beams in mechanical, electrical, and plumbing installations. It accommodates a 1/2-inch diameter threaded rod and is rated for a 470-pound load capacity. Constructed from iron with a black finish, it provides durable support in overhead suspension applications. This clamp is typically installed by licensed HVAC technicians, plumbers, electricians, and pipefitters working on pipe hangers, conduit supports, or duct suspension systems where a compact, low-profile top-mount connection is required.

The 825-12 is suited for use in light commercial and residential construction where threaded rod suspension from beam flanges is standard practice. Its junior profile makes it a practical choice in congested overhead spaces where a full-size beam clamp would not fit. The 0.88-inch overall width keeps the footprint small without sacrificing the rated load capacity. It is commonly used in HVAC duct hangers, electrical conduit support runs, and plumbing pipe hanger assemblies attached to structural steel.

Compatibility

Designed as an OEM-style replacement or direct-use top beam clamp for structural steel flange suspension applications using 1/2-inch threaded rod in mechanical and electrical trade installations.

Installation Notes

Installation is performed by licensed tradespeople including electricians, plumbers, and HVAC mechanics. Power down or isolate any nearby energized systems before working in the overhead space. Ensure the structural beam flange thickness falls within the clamp's rated engagement range before applying load. Follow applicable NEC, IPC, or IFGC hanger spacing requirements for the system being supported.
