S1316A "Positive Locking" SHUR-LOC® hook which may be used for lifting personnel. Meets OSHA Rule 1926.550 (g).
Design Factor 4:1
The top swivel design on the UB500 assures the ball remains stationary if the wire line spins.
The swivel incorporates a sealed roller thrust bearing together with a grease fitting for easy lubrication.
Each ball can be equipped with the new McKissick® US-422T Wedge Socket which can be easily adjusted to fit

various sizes of wire rope by changing the wedge (Ensure that correct wedge is used for selected wire rope size).

All hooks used on UB500 Overhaul Balls (S320, S320N, & S1316A) are forged from alloy steel. The S320 & S320N hooks come complete with latches.

The S320 hook (PL latch) and the S320N hook (S4320 latch), with proper latch attached, may be used for personnel lifting when secured with proper device (Bolt, nut, and pin for the PL latch; Cotter pin for the S4320 latch). Meet OSHA Rule 1926.550(g).
