The DMM UltraO Screwgate Oval is a symmetrical oval locking carabiner designed for rope access, tree care, fall arrest, climbing, and pre-rigged rescue systems. Its balanced oval shape allows multiple connectors, slings, ropes, and pulleys to be positioned centrally, making it particularly useful when equipment needs to remain stable and properly aligned under load.

The round basket helps connected equipment self-centre when weighted, while the symmetrical design means the carabiner can sit comfortably in either orientation without requiring rotation within the system. With a 25kN major-axis MBS and 22mm gate opening, the UltraO combines dependable strength with easy equipment connection.

Symmetrical Oval Design

The oval profile of the DMM UltraO Screwgate Oval provides a balanced connection point for technical rope systems. Its symmetrical basket allows connected equipment to remain comfortably positioned in either direction, reducing the need to rotate the carabiner within a system.

Central Positioning Under Load

The rounded basket shape helps connection points self-centre when the carabiner is weighted. This makes the UltraO particularly useful when several items such as ropes, slings, pulleys, or other connectors need to share the same connection point.

Taperlock and Clean Nose

DMM’s patented Taperlock closing mechanism uses a specially flared nose profile to increase gate push-in and cross-gate strength. The clean nose design also helps reduce snagging when connecting ropes, slings, and other equipment.
