Carbo Block 40 mm lightweight, heavy-duty pulley, sail block with ball bearing, extremely reliable

The powerful, smooth-running 40 mm Carbo block impresses with its low weight, high load capacity, and reliability. The cheeks and disc 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 capacity. The stop bracket directs the force directly to the block center. The hole in the block interior can be used instead of a becket.
