The Ronstan Ball Bearing Single Block with Loop Mount is a high-performance block designed for lightweight attachment with technical line. Replacing metal hardware with a loop mounting reduces weight and provides dynamic self-alignment with the load. Low-friction ball bearings ensure smooth, precise line flow under tension. It is an ideal technical solution for racing systems that demand low weight, structural strength, and versatility in dynamic running rigging.

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.
