Corrosion Resistant durable paint finish protects against corrosion in harsh environments.

Dual Function Cable Anchor for quick disconnect of wire rope with swaged ball fitting, or recessed cable anchor with set screw for wire rope with unfinished end.

Large Diameter Drums minimize wear to the wire rope and help extend its life.
