Ultra D

The Ultra D is similar in size to the Ultra O but with even greater strength due to the back configuration. The pronounced D-shape forces the loading along the major axis of the carabiner to maximise strength. Perfect for use at the end of lanyards, and in fact for most other working at height applications.

D-shaped connector bodies are designed to force the loads closer to the spine of the connector (the strongest orientation), therefore maximising strength. These are probably the most basic of all connectors in terms of shape, but this makes them a perfect choice in applications where strength and simplicity are paramount.

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
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
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.
ANSI Kwiklock
ANSI Kwiklock - A very strong 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. ANSI
Kwiklock gates rate to a minimum 16kN in minor axis, side loading and gate face loading tests, and conform to ANSI Z359.12 (2009).
Locksafe
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.
ANSI Locksafe
ANSI Locksafe - A very strong auto-locking gate requiring three separate actions to open. Locksafe gates give extra security in complex rigging systems such as those featuring running ropes and remote anchors. ANSI Locksafe gates rate to a minimum 16kN in minor axis, side loading and gate face loading tests, and conform to ANSI Z359.12 (2009).
Screwgate
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.
