Ultra O

The perfect locker for use with pulley systems, swivels or shackles. The Ultra O is a symmetrical locking carabiner that allows the equipment attached to it to sit centrally at both ends of the carabiner - this means that the Ultra O has very stable loading characteristics because attachments will naturally self-centre under load with minimal movement of the biner. This characteristic makes it ideal for use with assisted braking devices, pulleys, swivels and shackles. It is also desirable for rigging where it is imperative that anchors are not shock loaded. 
The Ultra O makes a good belay carabiner for tube devices as well, as the rope sits centrally, flows well and the carabiner tends to self-right in the belay loop and avoid cross loading. 
Manufactured in tactical colours, it is suited to military and tactical climbing requirements in both mountain and urban environments.

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.

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.

I have been using the Ultra O locking biner in conjunction with my Petal Gri Gri for sport climbing – the biner has performed brilliantly. UKC
