The Loop-Head Wire Block is a high-performance solution designed for lightweight attachment with textile strops. Its metal sheave resists steel-wire abrasion and ensures smooth rotation under high tension. The loop-head design provides simple installation and automatic alignment with the load while eliminating the weight of traditional metal hardware. It is the ideal technical choice for cascade systems and running backstays where low weight and durability are critical.

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.
