Crosby A-342 Alloy Master Links
Alloy Steel Quenched and Tempered.Individually proof tested to values shown with certification unless otherwise noted.
Proof tested with fixture size to prevent localized point loading per ASTM A952.
Proof test certification shipped with each link.
Crosby products meet or exceed all the requirements of ASME B30.26 including identification, ductility, design factor, proof load and temperature requirements.
Importantly, Crosby products meet other critical performance requirements including fatigue life, impact properties and material traceability, not addressed by ASME B30.26.Sizes from 1/2 to 2 inch are drop forged.

*Minimum Ultimate Load is 5 times Working Load Limit. Based on single leg sling (in-line load), or resultant load on multiple legs with an included angle less than or equal to 120.
Proof test load equals or exceeds the requirement of ASTM A952(8.1) and ASME B30.9-1.4 for the chain size and number of legs.
Welded Master Link.
