Ronstan Single - RF46100

Ronstan 40mm Single Ratchet - RF46100 auto, swivel shackle head


Ronstan 40mm Orbit Ratchet Blocks - Up to 14:1 holding power - highest available!
This automatic model, the ratchet mechanism engages when load is applied, but switches off when it's released. This lets the sheet run out smoothly and freely-great for rapid easing of the sheet and for gybing asymmetric spinnakers.

Swivel shackle head for unlimited block rotation and compatibility with sharp fixing points.
