Overview

The ABB AB243R3/8EG U-Shaped Retro Strut Washer is a precision-engineered fastener engineered for secure attachment to 3/8" metallic framing channels. This silver-galvanized washer provides a robust allowable load rating of 610 lbf (3.25 kN) with a factor of safety of 2, ensuring reliable performance in structural applications. The U-shaped design enables retrofitting into existing 1 5/8" framing channels without disassembly, making it ideal for maintenance, upgrades, and space-constrained installations. Designed for compatibility with standard strut systems, this washer distributes load evenly to prevent deformation or slippage of threaded rod assemblies. The silver-galvanized finish delivers corrosion resistance in indoor and outdoor environments, extending service life in industrial, commercial, and utility settings. Use this washer for mounting brackets, conduit supports, cable trays, or other structural attachments where secure, vibration-resistant connections are required. Part of the AB243R series, this washer is manufactured from low carbon steel with a silver-galvanized coating for enhanced durability. The product is available in 1/4", 3/8", and 1/2" rod diameters to match application requirements. For 3/8" threaded rod, the nominal diameter (∅D) measures 7/16" (11 mm), with an overall width of 19/32" (15.1 mm) and height of 25/32" (19.8 mm). The washer’s design ensures a tight fit within metallic framing channels, providing stability under dynamic loads. This retro strut washer is a critical component in electrical, mechanical, and HVAC installations where secure, long-lasting connections are essential.
