Ronstan Series 40 Ball Bearing Orbit Block Manual Ratchet
Ronstan Series 40 Ball Bearing Orbit Block Manual Ratchet
Manual ratchet option
Now you can enjoy the flexibility of setting up your fitout exactly to suit yourself. Ronstan is the only company that offers a 40mm ratchet block with both auto and manual engagement models.
Manual modes allow the ratchet mechanism to be switched on or off as required. This is the preferred mainsheet set-up for many top sailors.
Selected Series 40 models.
Awesome ratchet block holding power
Quite simply, Ronstan Ratchet Orbit blocks have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 of our patented sheave cross-hole geometry. The Series 40 delivers up to 14:1 holding power, almost double that of our nearest competititor.
The unique sheave design has 8 gripping faces which directly resist loaded line movement. Traditional designs have an angled resistance to line movement. Our Generation 2 design has straight resistance faces which both distribute the load and minimise rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load.
Smooth easing of sheets
With auto models the sheet runs out smoothly and freely as soon as the ratchet mechanism disengages. When engaged, and with manual models, the sheave cross - hole geometry eliminates the 'shuddering' ease-out that you can expect from traditional v-groove ratchet blocks.
Low profile stand-up kit allows 0° or 90° alignment
Stand-up kits feature a clatter-free rubber boot. It's a neat low-profile solution which allows full articulation.
Features:
- Up to 14:1 holding power - highest available!.
- Smooth easing of sheetsManual ON/OFF ratchet selection.
- Swivel shackle head for unlimited block rotation.
- Stainless steel shackle head and compatibility with sharp fixing points.
