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.

• 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.
• Oval carabiners have curved rope baskets for compatibility with slings, ropes, pulleys, and devices. The baskets allow attachments to self-centre when loaded, giving greater stability in systems that D shaped carabiners. Their symmetry allows them to work both ways in rigging systems.
• 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.
