Harken's 40mm 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.
Sheave is made of carbon-black Delrin for UV protection, and it turns on stainless steel spacers.
The 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.
