HARKEN 29mm Carbo AirBlocks®

From the folks who invented ball bearing blocks, this line of blocks boasts an excellent strength-to-weight ratio. The plastic in their sideplates, sheaves and balls makes them 30% lighter, 60% stronger and generally less expensive than equivalent conventional blocks.

The tiny 29mm block is extremely strong. 29mm doubles and triples feature a U-lock to hold the swivel in the front or side position, or allow it to spin freely. Use the 29mm Carbos as mainsheet blocks on dinghies, or for low-friction applications on any size boat. Recipient of both the Dame Award and Sail Magazine's Freeman Pittman Award for innovation
