The Ronstan Ball Bearing Orbit Block™ with Dyneema® Link Head represents the ultimate combination of low weight and strength. It replaces the steel shackle with a Dyneema® SK75 loop, dramatically reducing weight and providing a flexible connection that self-aligns perfectly with the direction of load. High-efficiency ball bearings deliver minimal friction and immediate response under tension. It is the definitive technical solution for high-performance racing, increasing agility while eliminating the risk of impact damage to the deck or mast.

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.
