• 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 US422 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).
• Design Factor 4:1
