The Crosby A-1337 Lok-A-Loy® 10 Coupling Link delivers on every count. Engineered specifically for Grade 80 and Grade 100 alloy chain sling systems, the A-1337 maintains the full Working Load Limit of the connected sling assembly while providing fast, reliable, tool-free connection between chain, master links, and hooks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLok-A-Loy® Design – Fast Assembly, No Tools Required\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe A-1337's Lok-A-Loy® alloy locking pin and sleeve system allows quick, secure coupling without specialized installation tools — reducing assembly time on the shop floor and in the field without compromising connection integrity.
