HARKEN triple pulley 57mm Carbo 2617

Carbo 57 mm triple pulley with swivel and Cam-Matic® 150 stopper.
Carbo AirBlocks® pulleys are 60% stronger and 30% lighter than our classic pulleys.
The resin-Nylon composite cheeks are reinforced with long glass fibers allowing the realization of a compact pulley with a high strength-to-weight ratio.
Ball bearings, sheaves and cheeks are carbon black treated for superior UV resistance.
The blocks are fitted with Cam-Lock or U-Lock locking systems to lock the shackle parallel or perpendicular to the sheave or allow it to pivot freely to prevent twisting of the rope.

The high strength 57mm Carbo range benefits from a wide range of applications.

mainsail on catamarans.
