Product Information
Automatic ratchet block
Now you can enjoy the flexibility of setting up your ratchet blocks to suit yourself. Ronstan is the only company that offers a ratchet block with both auto and manual engagement modes*. In the auto mode of 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. In manual mode, the ratchet mechanism can be switched on or off as required. This is the preferred mainsheet set-up for may top sailors. Try the block in both modes and see which you prefer - you really can't go wrong.
Selected Series 55 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. Its holding power is up to 21:1, almost double that of our nearest competitior. The unique sheave design has 12 gripping faces which directly resist loaded line movement. Traditional designes have only 8 faces with 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.
Materials
Sheave: Hard anodized Aluminum
Ball Bearings: High compression strength carbon black Acetal
Frame/Cheeks: Toughened, glass fibre reinforced Nylon
Rope Link: UV stabilised, multi-strand impregnated SK75 Dyneema®

Never pop balls
Color: White
These things are the best balls you can buy. My dog loves playing with them and chewing on them. And she has never popped one they are a great purchase if your dog usually pops other balls. These are solid and light weight

Tough, light weight, bouncy
Color: Yellow
Light weight but very tough and bouncy. My dogs don’t or can’t destroy these like they can tennis balls.

Perfect playtime ball
Color: Yellow
We’ve had these balls for almost a year and still have all of them. They’ve been to the lake, countless dog parks, and chewed on at home and they’re all still in perfect condition. Our dog is a 70lb English shepherd who’s no stranger to ruining balls

NOT for aggressive chewers!
Color: Yellow
My dog destroyed this ball within 10-15 minutes of use. He is a 65 lb German Shepherd. I do not recommend these balls for aggressive chewers.

So Far So Good
I adopted a young adult dog less than 2 weeks ago. She had spent over 12 hours a day in a crate and has excessive energy and anxiety built up. She is a strong chewer. So far, out of 6 toys, this is the only one still in one piece. It appears sturdy and extra bouncy. So much better than regular tennis balls.
