The Ultra D is similar in size to the Ultra O but with even greater strength due to the back configuration. The pronounced D-shape forces the loading along the major axis of the carabiner to maximise strength. Perfect for use at the end of lanyards, and in fact for most other working at height applications.
D-Shaped for simplicity; loads connector along the major axis
D-shaped connector bodies are designed to force the loads closer to the spine of the connector (the strongest orientation), therefore maximising strength. These are probably the most basic of all connectors in terms of shape, but this makes them a perfect choice in applications where strength and simplicity are paramount.
Keylock clean nose for snag free connection
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.
Captive bar option for security
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.
