The automatic A60 ratchet block is designed for dynamic applications on dinghies and keelboats and features a ø60 mm composite sheave. 

• The block is designed with lightweight Delrin ball bearings and the sheave automatically changes from free-turning to ratchet when the load increases. The sailor decides when the automatic ratchet kicks in.
• The switch-over point is set using an allen key to adjust a screw inside the sheave. Fast, simple, precise.
• A swivel lock, a plastic washer which is placed between block body and shackle, is included for fixed 0° or 90° shackle position.
