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.
