Top Swivel Overhaul Balls/Type 4

Gunnebo Johnson introduced this versatile style over forty years ago, providing more easily accessible upper fittings. Top swiveling models allow the rope and just the top fitting to rotate, facilitating positioning of the hook and load.

This style has become so popular that over 130 models are now offered, from 40 pounds to 1500 pounds, and from 4 tons WLL to 30 tons WLL. This style is also available with the world-famous Gunnebo self-locking BK hook.

4 through 30-ton capacities; 4 to 1 design factor; 59 through 1,342 lbs. weight
