The DMM Ultra O's is a very stable locking carabiner that gives predictable loading and allows attachments to sit centrally.
Durolock - An auto-locking gate requiring four separate actions to open. The most secure gate in complex and dynamic rigging systems, the Durolock maximises protection from accidental gate opening.
• The Ultra O's symmetrical rope baskets are ideal for assisted breaking devices, pulleys, swivels and shackles. They also give stable loading characteristics, as attachments can self-centre under load with minimal movement from the carabiner.
• Keylock nose eliminates snagging. This carabiner's nose slots into a groove in the gate, allowing it to achieve full strength without a gate notch. This creates a clean internal profile that won't catch on gear, bolts or slings, giving easier clipping and removal from systems.
• I-Beam construction for optimum strength to weight ratio. I-Beam construction techniques allow carabiners to be lighter without compromising strength. This is achieved through hot forging, a process which allows metal to be made into complex shapes that improve functionality.
