DMM Ultra O Locksafe Carabiner

The Ultra O Screwgate could be described as the perfect aid climbing biner – it certainly performs remarkably well in the big wall environment and the I-Beam construction gives it an excellent strength to weight ratio.

At some point all of us will need to use a pulley system, most likely in a rescue situation. Oval biners are important because they allow pulleys to sit in a correctly loaded and equalised position.

The symmetrical shape also stops them shifting under load and potentially dislodging a marginal gear placement. The locking gate adds a final element of security to the system.

• Oval shaped locking biner
