Thomas Betts 500SC Standard Beam Clamp 450 Lb 1/4-20 Rod

Product Description

The THOMAS BETTS 500SC is a standard beam clamp designed to attach threaded rod to structural steel flanges in mechanical, electrical, and plumbing suspension systems. It accepts a 1/4-20 threaded rod and supports a rated load capacity of 450 pounds, making it suitable for moderate-duty pipe, conduit, and equipment hanger applications. Constructed from malleable iron with a gold galvanized finish, the 500SC resists corrosion in typical indoor commercial and industrial environments. The clamp fits flange thicknesses up to 15/16 inches. Licensed contractors and pipefitters install this hardware during rough-in as part of suspended support assemblies in both new construction and retrofit projects.

The 500SC is intended for use in commercial and industrial construction where threaded-rod hanger systems are required. Common applications include suspending conduit runs, pipe hangers, HVAC duct support assemblies, and mechanical equipment from structural I-beams, wide-flange beams, and similar steel framing. It is appropriate for ceiling suspension systems in warehouses, data centers, mechanical rooms, and manufacturing facilities where a 1/4-20 rod size is specified by the engineer of record.

Key Features

• CSA certified under LR-63683

Compatibility

Designed as an OEM-style standard beam clamp compatible with 1/4-20 threaded rod hanger systems on structural steel flanges up to 15/16 inches thick. Consult project specifications to confirm rod size and load requirements before installation.

Installation Notes

Installation is typically performed by licensed electricians, pipefitters, or mechanical contractors per applicable NEC, IPC, or IFGC requirements. De-energize or de-pressurize any adjacent systems before working in the installation area. Seat the clamp firmly on the beam flange and tighten the clamping bolt to secure the assembly before attaching the threaded rod and hanger load. Do not exceed the rated 450 lb load capacity for this clamp size.
