Harken's 57mm Cruising ESP Sheave is self-contained and designed for sailors to use in custom applications.
Use this Cruising ESP sheave to handle high static loads from halyards and reef lines.
Contained sideload ball bearings allow sheaves to spin freely when loads are released. This sheave requires a sideplate for the sideload ball bearings to roll on.
Sheave is made of carbon-black Delrin for UV protection, and it turns on stainless steel spacers.
