Cast Screwy® choker ferrules have set the standard for logging choker ferrules.
The innovative cast Screwy contour matches the contour of the wire rope. That means maximum contact between the ferrule and rope for greater grip strength. The tapered end design eases insertion into choker hooks and butt hooks. Pushing hooks under logs is also easier.
Screwy Drumline Ferrules
Screwy drumline ferrules incorporate the cast Screwy design in a shorter ferrule, designed specifically for attaching winch lines to winch drum pockets.
Note: Drumline ferrules develop less holding power than choker ferrules and should only be used to attach wire rope to winch drums. Never load drumline ferrules directly. Always leave at least three wraps on the drum when it's under a load.
