Ultra D

The Ultra D is a very strong and versatile high-volume carabiner that is suited to heavy duty rigging and rescue work. The carabiner's shape is a hybrid of the Ultra O and the Zodiac shapes; the resulting longer top bar, wider gate opening, and larger internal volume makes it very easy to use with gloves and when working with thick rope and slings. Plus, the ability for it to accommodate knots at either end and hold pulleys symmetrically makes it very versatile in rigging systems. 
 
The carabiner comes as standard with a matt grey anodised finish, but can also be supplied with a matt black anodised finish or with more specialist Ceracote finishes in a range of tactical colours from artic white to desert coyote. The Ceracote coatings are also available with a reduced IR signature. The Ultra D Kwiklock ANSI with a Cerakote tan back is used in USAF helicopter lanyard systems.

The nose design on these carabiners helps them resist shearing forces and achieve high side loading strength ratings. Taperlock is an evolution of our Keylock design, which gives a clean internal profile that prevents snagging on gear, bolts and slings.

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.
