5:1 Design Factor. Applications with wire rope and synthetic sling generally require a Design Factor of 5.

Based on single leg sling (in-line load), or resultant load on multiple legs with an included angle less than or equal to 120 degrees.

Proof Test Load equals or exceeds the requirement of ASTM A952(8.1) and ASME B30.9.

Chain slings require that the Design Factor be 4:1. Refer to applications & warnings to determine product's actual Ultimate Load.

There are no manufactured flats on links over 1 1/4" (32mm).
