Product Description Harken 3T Carbon V™ BlockThe 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) 56 mm Sheave Ø (in) 2 3/16 in Length (mm) 77 mm Length (in) 3 in Weight (g) 113 g Weight (oz) 3.99 oz Maximum line Ø (mm) 11 mm Maximum line Ø (in) 7/16 in Maximum working load (kg) 3000 kg Maximum working load (lb) 6600 lb Breaking load (kg) 6000 kg Breaking load (lb) 13200 lb
