STRONG CONNECTOR APPLICATIONS.
The Ultra D karabiner 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.
 
Screwgate
Manual locking gate requiring screwing/unscrewing of the barrel to lock/unlock.
 
Kwiklock
Auto-locking gate requiring two distinct actions to open.
 
Locksafe
Auto-locking gate requiring three distinct actions to open.
 
Durolock
Auto-locking gate requiring four distinct operations to open. Force must be maintained throughout or the gate returns to safe (locked).
 
Kwiklock ANSI
Same gate action as Kwiklock but the connector is also required to exceed 16kN in minor axis, side load and gate face tests.
 
Locksafe ANSI
Same gate action as Locksafe but the connector is also required to exceed 16kN in minor axis, side load and gate face tests.
