    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 competitor. The unique sheave design has 12 gripping faces which directly resist loaded line movement. Traditional designs 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 minimize rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load.

    Simple and secure attachment

    The Dyneema® Link is easily fitted and is retained securely by a molded retainer clip. The flexible link can be left with one end attached to the block when fitting - no more lost shackle pins. The system is compatible with Dyneema®/Spectra® strops, webbing and caron connection points - much more so than steel loop tops or shackles. In auto mode, the sheet runs out smoothly and freely as soon as the ratchet mechanism disengages. In manual mode, the sheave cross-hole geometry eliminates the 'shuddering' run-out that you can expect from traditional v-groove ratchet blocks.

    Scent: Coconut, Size: 0.15 Ounce (Pack of 1)
    I've been using this lip balm for a while now, and I'm very happy with it. It keeps my lips moisturized without feeling greasy or sticky. The coconut scent is pleasant and not overpowering, and the SPF 30 protection is a great bonus when spending time outdoors. The balm goes on smoothly, lasts a long time, and helps prevent my lips from drying out in the sun. I also like that it contains aloe vera and vitamin E. Overall, it's a great lip balm, and I would definitely purchase it again.

    Worked like it was supposed to!
    Scent: Coconut, Banana, Watermelon, Size: 0.15 Ounce (Pack of 1)
    Each flavor has a great smell and flavor, goes on smooth and makes my lips soft! I trust this brand to have the SPF ro protect my lips. I bought this to use while in Puerto Rico 🇵🇷 for 10 days and didnt get burnt. I gave it a 4 star rating because it gives me a funny aftertaste in my mouth. My husband didn't experience this so maybe its just me. Regardless, it did what it was supposed to do!
