Ultra O

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.

Oval carabiner for rigging stability and central positioning of attachments

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 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.

Available with a captive bar to secure orientation and prevent tampering

Captive bars ensure carabiners load along their strongest axis by securing their orientation, and can also be used to create tamper proof systems that cannot be dismantled by users.

Durolock connector locking mechanism

Our unique Durolock mechanism minimises the chance of accidental gate opening. Earlier this year the versatile Ultra O connector was our fourth locking carabiner to be paired with this option. Watch this short video to find out more about the Durolock.

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.

Kwiklock - Auto-locking gate requiring two separate actions to open. Kwiklock gates are suitable when auto-locking gates are a necessity, but rigging systems are relatively static and anchor points are easy to monitor.

Locksafe - An auto-locking gate requiring three separate actions to open. Locksafe gates give extra security in complex rigging systems such as those featuring running ropes or remote anchor points.

Screwgate - Non auto-locking gate which requires two actions to open, and is easy to use with one hand. Screwgates are suitable in systems where anchor points can be easily monitored and are unlikely to be affected by running ropes.
