Harken 307 38mm 1.5" Sheave Replacement For High-Strength Wire Blocks
HARKEN 307
38mm High-Strength Wire 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) sheaves minimize friction. The 1" (25mm) wire sheave uses low-friction washers for this purpose.
