The 57mm single swivel ratchet is ideal for sheet blocks and catamaran mainsheet systems. The ratchet block features a simple yet positive on/off switch for easy control. Available in one size.
The 57mm single swivel ratchet features a slot shackle swivel head and advanced carbon composite cheeks which provide great strength at a low weight. There is also a soft moulding on the cheek which protects the deck from wear when the block is at rest. The cheeks encapsulate a hard anodised CNC'd sheave for ultimate grip and wear resistance.
