    Product Information

    Core Blocks™ are a true all round solution. A tuned 2-stage bearing system provides excellent performance across the full working load range with an integrated thrust bearing feature and the resilience to handle high dynamic or static loads. Acetal sheave, alloy cheeks and stainless fixings complete the durable package. For reliability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.

    Universal Bearing

    Dynamic and high static load performance

    The Ronstan Universal Bearing incorporates our proven 2-stage bearing system

    Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction.

    Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance.

    Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn’t perfect. Particularly important for cheek blocks.

    Alloy cheek plates

    Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimization and the cut-away design minimizes weight and allows easy fresh water rinsing of salt and debris from the bearings. Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimizing rope wear.

    Fully articulated stand-up

    Stand-up models have a low profile linkage that provides full rotation and articulation. A high strength precision cast padeye minimizes the footprint and a dedicated rubber boot ensures the block is held upright when not loaded.

    Applications

  • Ideal for mainsheet, halyard and spinnaker sheet applications on boats to 12m (40ft).

  • Various control line applications on larger yachts.

  • Alloy sheave models are available for use with wire.

    Great quality case and keyboard
    Color: Purple, Color: Purple
    Super good quality case, I was actually surprised since it’s such a good price. It fit my 10.9 inch perfectly! Keyboard has magnetic attachment to the case which is super handy, and it connected with Bluetooth seamlessly. Keyboard isn’t silent, it’s on the louder side, but not too loud at all and it doesn’t bother me at all because I prefer clickier keyboards. Oh also something that’s really cool is that you can change the colors of the keyboard, love that!

    Amazing!
    Color: Midnight Green
    The Hamile Keyboard Case for iPad (11th & 10th Generation) is a practical accessory for turning your iPad into a more laptop-like setup. Designed with a detachable wireless keyboard and protective case, it’s aimed at students, professionals, and anyone who types frequently on their tablet. One of its most appealing features is the 7-color backlit keyboard, which makes typing easier in low-light environments while also adding a customizable, stylish look. The backlighting can usually be adjusted in brightness and color, making it both functional and fun to use. The keys are generally responsive and comfortable enough for everyday typing tasks like emails, notes, and document work. The case itself provides decent protection for the iPad, helping guard against scratches and minor bumps. It also holds the tablet at a stable viewing angle, which is useful for video calls, studying, or streaming. The wireless connection is typically simple to set up via Bluetooth, and the keyboard can be detached when not needed.

    Great quality case, keyboard doesn’t work as intended
    Color: Dark Cherry
    Case is fine and good quality but the keyboard doesn’t work as intended. Bluetooth connects great but the keyboard is formatted incorrectly. For example, when I try to use a dash, it puts an apostrophe instead. I have no idea how to reformat it myself. I’d love just a replacement keyboard
