DMM Ultra O Locksafe Carabiner

The symmetrical oval shape is ideal for rope access and rescue systems because it allows pulleys and other hardware to self-center, preventing the carabiner from rotating or shifting under load. It also eliminates the 'clicking' sensation often felt with asymmetrical shapes.

Locksafe is DMM's auto-locking gate system, which requires three distinct actions—slide, twist, and pull—to open. This triple-action design provides a high level of security, making it nearly impossible for the gate to open accidentally while in use.

Yes, the Taperlock nose profile is designed to be flush with the gate, which significantly reduces the chance of ropes, slings, or webbing catching on the nose during clipping or unclipping. It also helps increase the gate's cross-gate strength.

Absolutely. While it is a staple in industrial rope access and tree care, its certifications (EN12275 and UIAA121) confirm it meets the safety standards required for climbing and mountaineering applications.

The I-Beam construction removes excess metal from non-load-bearing areas, allowing the carabiner to be strong and durable without unnecessary weight. This gives you a high strength-to-weight ratio, which is beneficial when you are carrying a full rack of gear.
