DMM Ultra O Durolock Carabiner

Description

The ultra-light, clean nose Ultra O carabiners are the mainstay of our 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 connectors 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 connector. The symmetrical basket mean rotation within systems is not required as they sit comfortably either way round.
DMM’s patented ‘Taperlock’ closing mechanism increases gate push-in and cross gate strength using a special flared profile on the nose of the carabiner, as well as allowing a snag free connection for your ropes, slings and devices.
Many of our connectors can be supplied cross-drilled to accommodate captive bars. This means that the lanyard or attachment cannot be removed and ensures that the direction of force applied in the event of a fall is along the major axis of the connector, giving maximum strength and holding power. The captive bars themselves are not for load bearing use.
