DMM Ultra O Quicklock double action climbing carabiner is characterized by an oval shape and twist-lock closure.
Ultra O Quicklock is hot forged, lightweight, and durable. Its large dimensions make it extremely effective with thick ropes and allow you to handle it comfortably even while wearing gloves.
Ideal for work at height and rescue maneuvers thanks to the twist lock system that guarantees you a high level of quality and safety.
The oval shape allows paired devices and pulleys to work in both load directions, ensuring exceptional stability and symmetry.
