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.

Taperlock nose gives high push-in strength

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.

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.

Large gate opening and high internal volume for easy handling and more attachment options

The gate opening is the distance between the nose of a carabiner and the gate when it is fully opened. Larger gate openings make a carabiner easier to use while wearing gloves, and with thick ropes and slings. Internal volume refers to the area inside a carabiner, and large internal volumes mean easier attachment and removal of multiple devices, knots and slings.

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.
