Thomas Betts AB-241-1/2 Strut Channel Square Washer

Product Description

The THOMAS BETTS AB-241-1/2 is a square washer designed for use with strut channel and unistrut framing systems. It provides a broad bearing surface at 1/2 inch bolt size, distributing load across the strut flange to reduce pull-through and maintain a secure mechanical connection. Constructed from steel with a gold galvanized finish, this washer resists corrosion in both indoor and light outdoor installations. Electricians, mechanical contractors, and pipe support crews use this type of hardware when assembling channel framing assemblies for conduit support, equipment mounting, and utility rack systems.

This square washer is suited for use with Thomas Betts strut channel and compatible channel framing systems in commercial and industrial applications. Typical install scenarios include electrical conduit support structures, mechanical equipment mounting, and ceiling or wall-mounted utility racks. It corresponds to Unistrut part number P1064 and B-Line part number B202, making it a cross-referenced replacement or supplement in multi-brand strut channel assemblies.
