Thomas Betts M-775-L-1/2B L-clamp Locknut 850 Lb

Product Description

The THOMAS BETTS M-775-L-1/2B is a steel L-clamp with locknut designed for securing threaded rod to structural flanges in mechanical and electrical support installations. Rated at 850 pounds load capacity, it accepts rod sizes up to 0.5 inches and accommodates flange thicknesses up to 0.75 inches. The integrated locknut prevents loosening under vibration or dynamic load. Licensed electricians, pipefitters, and mechanical contractors use this clamp to build and anchor trapeze hangers, conduit supports, and equipment mounts in commercial and industrial facilities.

This clamp is suited for use in commercial and industrial construction where threaded rod support systems are required. It is commonly installed in ceiling and overhead support assemblies for conduit runs, HVAC duct hangers, and piping systems. The steel construction makes it appropriate for interior applications where structural strength and reliable clamping force are priorities.

Installation Notes

Installation is typically performed by licensed electricians or mechanical contractors in accordance with applicable NEC and local building code requirements. De-energize any nearby electrical equipment and relieve system loads before installing or adjusting support hardware. Use appropriate hand tools to torque the locknut securely without over-stressing the clamp body. Verify that the total suspended load does not exceed the 850 pound rated capacity of the clamp.
