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

Oval biners are important because they allow pulleys to sit in a correctly loaded and equalised position. Their symmetrical shape 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
  • Ideal for pulley systems and aid climbing
  • Strong and lightweight I-Beam construction
  • Generous rope radius

Strength (gate closed): 25kN
Strength (gare open): 7kN
Strength (minor axis): 7kN
Gate opening: 22mm
Weight: 65g

DMM Ultra O Screwgate

Strong Screwgate carabiner, easy action gate, fits the hand well and operates easily. very pleased with the quality of the design and materials, Not best for using with a hunter or even a clove hitch but excellent for belay slings and tying rope back into harness.
