    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®

    REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
    Size: 8, Color: Black Patent
    I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.

    Love these flats!
    Size: 9 Wide, Color: Black White Faux Snake Skin, Size: 9 Wide, Color: Black White Faux Snake Skin
    One of my favorite pair of flats! I’ve had these for several years and they are still comfortable, in good shape and really add a little spice to my outfits. I can wear these all day and not have any foot pain or discomfort as a result. The quality is good, fit is perfect and I tend to have difficulty with shoes due to bunions. Love these!!

    I love these shoes so much I had to write a review. So comfortable. Cushioned. Fits perfectly especially if you are more on the wide side. They are soft. Flexible. Easy slip ons you can walk around in all day. I want to try more colors.

    Great buy
    Size: 12 Wide, Color: Black Faux Leather
    I absolutely love these Amazon Essentials Belice Ballet Flats! They are so comfortable right out of the box and fit my feet perfectly. I can wear them all day without my feet hurting, which is hard to find with flats sometimes. They’re also really cute and go with almost everything I wear. I find myself reaching for them all the time because they’re both comfy and pretty. Definitely a great everyday shoe, especially for the price!

    Loooove these shoes!
    Size: 7.5 Wide, Color: Chestnut Brown Faux Leather
    I have these in several colors, and they’ve become a true staple in my wardrobe. The Amazon Essentials Women's Belice Comfortable Slip-On Ballet Flats are exactly what I look for in an everyday shoe—simple, versatile, and comfortable right out of the box. The slip-on design makes them super convenient for busy days, and they pair effortlessly with everything from jeans to dresses to work outfits. They’re lightweight but still feel supportive enough for all-day wear, and I appreciate that they don’t require a break-in period. The fit is generally true to size, and the variety of colors makes it easy to stock up and rotate depending on the outfit. Overall, these are reliable, easy-to-wear flats that offer great value for the price. Not flashy, just consistently comfortable and practical—which is exactly why I keep coming back to them.
