Abb 500-SC Beam Clamp 1/4-20 Thread Malleable Iron

Product Description

The ABB 500-SC is a malleable iron beam clamp designed to attach threaded rod, wire, or conduit support assemblies directly to structural steel flanges. The clamp accepts 1/4 inch-20 threaded rod or fasteners and fits beam flanges up to 15/16 inches thick. Its malleable iron construction provides reliable load-bearing performance under the vibration and load cycles common in commercial and industrial mechanical, electrical, and plumbing installations. Electricians, HVAC pipefitters, and plumbing contractors use this clamp as a primary fastening point when overhead beam attachment is required without drilling or welding.

This clamp is suited for use in commercial buildings, industrial facilities, and institutional structures where conduit, pipe, duct, or equipment support hangers must be anchored to structural steel I-beams, wide-flange sections, and similar profiles. It is commonly used in electrical conduit runs, HVAC duct hanger assemblies, and piping support systems where a quick, secure beam attachment is needed above finished ceilings or in open plenum spaces.

Key Features

• Malleable iron construction for strength and resistance to cracking under load
• 1/4 inch-20 threaded openings accept standard threaded rod and machine screws
• Fits beam flanges up to 15/16 inches thick for compatibility with common structural steel sections
• No drilling or welding required for beam attachment
• Compact profile for use in tight overhead clearances

Compatibility

Designed as an OEM-style beam clamp for use with standard 1/4 inch-20 threaded rod hanger assemblies on structural steel flanges up to 15/16 inches thick.

Installation Notes

Installation is typically performed by licensed electricians, pipefitters, or HVAC mechanics in accordance with NEC, IPC, or IMC requirements for support spacing and load ratings. De-energize any nearby electrical systems before working overhead. Verify that the beam flange thickness falls within the rated range before tightening the clamp, and confirm the clamp seating is fully engaged on the flange before applying load to the hanger rod.
