Thomas Betts AB-241-1/4 Strut Channel Square Washer

Product Description

The THOMAS BETTS AB-241-1/4 is a steel square washer designed for use with strut channel systems. It fits a 1/4 inch bolt and provides a stable bearing surface at strut connections, distributing load evenly across the channel flange. Square washers are a standard hardware component in electrical and mechanical support systems where strut channel is used to mount conduit, cable tray, equipment, and unistrut assemblies. Electricians and mechanical contractors install this type of hardware daily on commercial and industrial jobsites.

This washer is intended for use with Thomas Betts strut channel and compatible channel systems. It is suited to both new construction and retrofit applications where strut channel is used for equipment support, pipe hangers, and electrical enclosure mounting. The square profile helps prevent bolt pull-through and rotation in the channel slot, making it a reliable choice for overhead and wall-mounted strut assemblies.
