An excellent aid climbing biner, and the perfect racking biner.

The DMM Ultra O Carabiner may look like a historical remnant from 1970s, but it's actually a very practical biner that works exceptionally well in pulley systems , which uses hot forged I-Beam panels to maximise its strength/weight balance.

Most climbers will see it as the perfect racking biner - it can hold a large number of wires without the awkward bunching that tends to happen with a conventional asymmetric biner. Its oval shape also means that the wires will slide round easily without snagging.

  • Clean nose oval straight gate biner
  • Strong and lightweight I-Beam construction
  • Very generous 9.75mm rope radius
  • Works well in pulley systems

Strength (gate closed): 25kN
Strength (gare open): 7kN
Strength (minor axis): 7kN
Gate opening: 24mm
Weight: 61g
