Product Description Harken 6.5T Carbon 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 are standard with 3D-molded carbon sideplates, titanium sheave, and captive titanium roller bearings. V blocks are easy to disassemble for inspection and maintenance.Specifications: Sheave Ø (mm) 82 mm Sheave Ø (in) 3 1/4 in Length (mm) 107 mm Length (in) 4 3/16 in Weight (g) 364 g Weight (oz) 12.84 oz Maximum line Ø (mm) 16 mm Maximum line Ø (in) 5/8 in Maximum working load (kg) 6500 kg Maximum working load (lb) 14300 lb Breaking load (kg) 13000 kg Breaking load (lb) 28600 lb
