DMM PerfectO Locksafe

The DMM PerfectO is a compact true oval carabiner that maintains ease of use, even one-handed. Its shape provides effective centring of loads and the fully rounded rope bearing areas increase carabiner and rope longevity.

A keylock nose allows snag-free operation. The Locksafe gate—which requires three specific movements to open—locks automatically, reducing the chance of human error.

Colin Toombs
Unsuitable for Pulleys or Ascenders

Excellent DMM quality and smooth gate action BUT they're not a good pairing for pulleys or ascenders. The problem is that the oval ends are fatter in the middle than the I beam sides which means that they won't sit straight but always twist on to the thinner sides cross loading the carabiner. Tried with Petzl and Wild Country ascenders and same problem on both. Also the radius is too small for use with emergency pulley wheels. Bought the Petzl OK carabiners and they don't have these issues. Two stars for DMM quality but no stars for application.
