17 in stock

The Ronstan Tube-Rivet Wire Block is an ultra-compact, lightweight component designed for installations where space is minimal and permanent attachment is required. Its metal sheave withstands steel-wire abrasion and provides efficient rotation under high tension. The tube-rivet mounting system allows the block to be installed directly through a hole in structures such as masts or booms, with the rivet acting as both axle and attachment point.

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.
