The DMM Ultra O Carabiner you know and love, now with a Quad Action locking gate for those that want the utmost security in their carabiners.

Symmetrical 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.
