Product Description

Harken 8T Aluminum V Block

The V block delivers another breakthrough in Harken’s loop block series for Grand-Prix racers. Harken engineers have simplified the mechanics by combining the axial and thrust bearings into a single bearing set of V-shaped titanium rollers. The result is a strong, lightweight block that offers unmatched efficiency at high loads, while spinning freely at low loads for smooth easing in light air.

Harken V blocks have aluminum sideplates, titanium sheave, and captive titanium roller bearings. V blocks are easy to disassemble for inspection and maintenance.
