Crosby S-1325A Grade 100 Chain Couplers – Reliable Connection for Chain and Fittings

The Crosby S-1325A Chain Coupler is a high-strength, single-piece connector designed to securely attach Grade 100 chain fittings with engineered flats to Grade 100 chain. Made from forged alloy steel, quenched, and tempered, this coupler is individually proof-tested to 2.5 times the Working Load Limit (WLL) and features a spring-loaded locking system to keep the chain in place under slack conditions. Suitable for both Grade 100 and Grade 80 chains, it offers easy assembly and disassembly without special tools. Available in sizes from 6mm (3,200 lbs WLL) to 16mm (22,600 lbs WLL), the S-1325A Coupler is fatigue-rated to 20,000 cycles at 1.5 times the WLL, making it a durable and dependable solution for lifting, rigging, and chain sling applications.
