DMM Ultra O Carabiner

6 items left

The ultra-light, clean nose Ultra O carabiners are the mainstay of the DMM carabiner range, and for good reason. Not only do they give high strength to weight ratios and feel great in the hand, they also help to keep components of a system aligned. The deep symmetrical basket allows pulleys, webbing, ropes and even other carabiners to 'centre' naturally and still allow easy stacking of components on either side. A connecting classic.

Oval Shape Allows Central Positioning of Devices

Oval carabiners are popular in rope access and tree care situations where multiple connectors, slings, ropes or even pulleys can be connected. They are equally at home in fall arrest situations or as part of a pre-rigged rescue system. The round basket shape allows any of the connection points to self-centre when weighted - this helps avoid the unnerving click that often happens with a more D-shaped carabiner. The symmetrical basket mean rotation within systems is not required as they sit comfortably either way round.


Non auto-locking gate which requires two actions to open, and is easy to use with one hand. Screwgates are suitable in systems where anchor points can be easily monitored and are unlikely to be affected by running ropes.

An auto-locking gate requiring three separate actions to open. Locksafe gates give extra security in complex rigging systems such as those featuring running ropes or remote anchor points.
