Block 40mm Carbo single Block with Becket – Harken

Carbo AirBlocks are 60% stronger and 30% lighter than our Classic blocks. Use the 40 mm Carbo for jib and mainsheet systems on high-performance dinghies and for loaded control lines on small keelboats. The nylon-resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Sheaves spin on high-load ball bearings with fitted races for low-friction operation. Ball bearings, sheave, and sideplates are UV-stabilized with carbon black for maximum protection.Max line size 10mmSheave(mm)40mmLength (mm)102mmWeight (g)48gShackle pin(mm)4mmMaximum line(mm)10mmMaximum working load (kg)220kgBreaking load (kg)735kg
