The Ronstan Ball Bearing Block with Loop Top is a high-performance block designed for lightweight attachment with technical or textile lines. By eliminating heavy metal hardware, the system provides a flexible connection that dynamically self-aligns with the load, reducing deck weight and preventing impact noise. Low-friction ball bearings ensure smooth rotation and immediate line response. It is ideal for racing and configurations requiring maximum efficiency, mounting versatility, and superior structural strength.

At Saildeck Gear, we specialize in technical rigging, blocks, winches, and deck hardware for boats between 30 and 60 feet. We know that every boat is different: working loads, mast dimensions, the type of maneuver, and how you use your boat—cruising, racing, or charter—all affect what you actually need.

That’s why we don’t publish a fixed price on the product page: we prefer to speak with you first.

Tell us which product you’re interested in and which boat you’ll be installing it on, and we’ll prepare a quote tailored to your setup, including technical advice and with no obligation.

If you have any questions about compatibility, measurements, or which part is right for your rig, you can also contact us here. We normally respond within 24–48 hours.

The information you provide will be used solely to respond to your inquiry. Please see our Privacy Policy for more information.
