Ferrules and End Fittings

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.

ESCO 40SS Stainless Steel

The popular ESCO popular 40SS cast stainless steel is formulated specifically for swaging. High initial ductility allows ESCO stainless steel to flow evenly around the wire rope during swaging, for total gripping strength and extremely high crack and fracture resistance. During swaging, ESCO stainless steel work-hardens more than any other swaging steel to provide toughness, on-the-job durability and corrosion resistance.

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.

Machined Choker Ferrules and End Fittings

ESCO offers choker ferrules and end fittings machined from tough steels, engineered specifically for swaging applications. Manufactured to exacting specifications and continuously monitored to ensure the highest quality, these ferrules are available in popular sizes at competitive prices.
