Overview

The ABB AB243R1/4EG U-Shaped Retro Strut Washer is a precision-engineered fastening solution designed for metallic framing channels, specifically engineered for 1/4" all-thread rod applications. This silver-galvanized washer delivers a secure, load-bearing connection with an allowable load rating of 150 lbf (1.07 kN) at a 2:1 factor of safety, ensuring structural integrity in demanding installations. Key specifications include a nominal rod diameter of 1/4" (6.35 mm), a washer width of 5/16" (8 mm), and a U-shaped design optimized for retrofitting onto existing 1 5/8" metallic framing channels without full disassembly. The silver-galvanized low-carbon steel construction provides corrosion resistance in moist or chemically exposed environments, extending service life while maintaining a clean aesthetic. This washer is part of the ABB Superstrut® accessory line, compatible with standard strut systems for electrical conduits, HVAC piping, and mechanical support structures. Its U-shaped configuration allows for quick installation over pre-assembled threaded rod assemblies, reducing labor time during upgrades or repairs. The product is cataloged under SKU AB243R1/4EG and aligns with UNSPSC code 31161812 for structural components. Ideal for industrial, commercial, and utility applications, the AB243R1/4EG ensures reliable load distribution and vibration resistance in strut-to-rod connections. Its compact dimensions (19/32" x 25/32" x 0.370") make it suitable for space-constrained installations while maintaining compatibility with standard 1/4" hardware. For larger loads or alternative channel sizes, ABB offers the AB243 series (gold-galvanized) and H123 series (Kindorf® compatible) with higher load ratings up to 1,130 lbf.
