DMM UltraO Carabiner

$19.95 - $28.95

Better Than Perfect

As a larger version of the PerfectO Carabiner, the DMM UltraO Locking Carabiner is the perfect shape for any time you need to rig, haul, or aid climb. The large, oval design centers loads easily, and the rounded sides reduce rope friction, saving both your rope and your gear from unnecessary wear. With a keylock nose that won't get stuck when it's time to break down your anchor and light weight for its size, the UltraO will help keep you and your gearing on the move.
