Sale price$72.95 Regular price$83.25

HARKEN 311 

Single High-Strength 2" Self-Contained Sheave Replacement

Harken self-contained sheaves are designed for sailors to use in custom applications.

Wire sheaves ride on high-load composite bearings. They are Hardkote-anodized with PTFE impregnation.

Ball bearings in the 1-1/2" (38mm) and 2" (51mm) sheaves minimize friction. The 1" (25mm) wire sheave uses low-friction washers for this purpose.
