Description

Crosby A-336 Lok-A-Loy® 6 Connecting Links

Crosby A-336 Lok-A-Loy® Connecting Links are forged alloy steel couplers used for connecting chain, master links, and hooks in various rigging assemblies. While they share a similar form to the A-1337 coupling links, the A-336 series carries a lower Working Load Limit (WLL) and must be applied with care when integrated into Grade 80 chain sling systems.

Key Features

  • Forged alloy steel construction – quenched and tempered for superior strength and reliability.
  • Individually proof tested at 2.5× Working Load Limit (WLL) with certification.
  • 4:1 design factor for dependable performance.
  • Lok-A-Loy® design allows easy assembly and disassembly using standard link sleeves and pins.
  • Meets applicable performance requirements of ASME B30.26 for rigging hardware.
  • Permanent identification markings include Working Load Limit, chain size, and Crosby name for traceability.
Important: The Crosby A-336 Lok-A-Loy® 6 Connecting Link can be used in lifting applications, but its Working Load Limit is lower than that of Grade 80 chain.

  • When incorporated into a Grade 80 chain sling, the sling must be downrated to match the lower WLL of the A-336 coupler.
  • Per ASME B30.9c, the Working Load Limit of a sling cannot exceed the lowest-rated component in the system.
  • Not recommended for Grade 100 or higher systems — use the A-1337 coupling link instead.
