The Clockwise Cheek R60 manual ratchet block is designed for spinnaker/gennaker sheet applications on dinghies and keelboats and features a ø60 mm composite sheave. The sheave has a clockwise direction when in ratchet mode and is therefore intended to be used for starboard sheet.

The block is designed with lightweight Delrin ball bearings and a switch to select ratchet function or a free spinning sheave. When the ratchet is activated it locks the sheave in one direction and allows the sailor to relax a bit without cleating the line. 

 Easy to install with 3 M5 screws.
