DMM Ultra O Duralock Oval Carabiner

When you're working up in the canopy, you need gear you can rely on blindly. This oval aluminum carabiner redefines safety in tree care by combining a proven symmetrical design with a state-of-the-art locking mechanism. Its uniform shape makes it the perfect partner for your friction hitch setups, especially when paired with the Hitch Climber pulley or other redirection pulleys. The standout feature of the oval design is its ability to self-center loads and attached hardware, such as swivels or shackles, under tension. This prevents annoying shifting and eliminates the jarring "click" or "snap" often caused by sudden load shifts in D-shaped carabiners.

However, the true innovation lies in the Durolock closure. This 4-way mechanism requires four precise movements to open, making accidental opening virtually impossible. As soon as you release the sleeve, the system locks automatically, providing the highest level of protection during your daily work in the crown. Despite this complex safety feature, the carabiner can be operated smoothly with one hand after a little practice. Furthermore, the keylock nose ensures fluid handling by effectively preventing snagging on ropes, slings, or gear loops. Whether as a central element in your rescue system or for daily use in rope climbing techniques - this carabiner delivers the stability and reliability you demand at height.
