Carbo double block 57 mm lightweight, heavy-duty sailing accessory, becket, ideal for dinghy and sports boat trim

The powerful, smooth-running 57 mm Carbo double block with becket impresses with its low weight, high load-bearing capacity, and reliability. The cheeks and sheave are made of high-strength, lightweight Carbo composite. Free-running Delrin ball bearings ensure smooth running, even under heavy loads. Round bearing shells distribute forces evenly and increase load-bearing capacity. The freely rotating pin can be locked in two positions. The heavy-duty, forged shackle guarantees secure attachment. Perfect for precise trimming of sheets on dinghies and performance-oriented sports boats, as well as for control lines, even on large yachts. The Carbo double block with becket is suitable for 4:1 and 5:1 ratios.
