The Nite Ize Figure 9 Carabiner tightens, tensions, and secures ropes without knots. Whether tethering a canoe to your vehicle, anchoring boxes to a dolly, or bundling wood, this carabiner secures loads quickly and keeps tension where you need it. Loop your rope through its strategically designed prongs, pull it tight, and it stays that way. A smart alternative to complicated cam-locking tensioning devices and bungee cords, the Figure 9 Carabiner also controls the release of high tension, avoiding sudden and dangerous unloading. Features 3 attachment methods for ultimate versatility: loop system, fixed end system, and anchor clip system. Also features laser engraved instructions ensure ease in operation, smooth and secure stainless steel wire gate closures, and lightweight, strong aluminum construction. Available in small or large. The small fits rope sizes 1/16'' to 3/16'' and holds up to 50 lbs. The large fits rope sizes 1/8'' to 3/8'' and holds up to 150 lbs.
