DMM Ultra O Locksafe Red 3-Stage Auto-Locking Carabiner

The Ultra O's symmetrical rope baskets are ideal for a variety of applications, including assisted breaking devices, pulleys, swivels, and shackles. Their oval shape allows for the central positioning of devices, making them a popular choice in rope access and tree care situations where multiple connectors, slings, ropes, or even pulleys need to be connected. The round basket shape allows any of the connection points to self-centre when weighted, helping to avoid the unnerving click that often happens with more D-shaped connectors.

One of the key features of the Ultra O is its stable loading characteristics. Attachments can self-centre under load with minimal movement from the carabiner, ensuring a secure and reliable connection. This makes them equally suitable for fall arrest situations or as part of a pre-rigged rescue system.

DMM's patented 'Taperlock' closing mechanism is another notable feature of the Ultra O. This 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 ropes, slings, and devices.

The Ultra O's keylock clean nose design further enhances its functionality, providing a snag-free connection that is essential in many outdoor activities.
