Product information & specifications
DMM Ultra D Locksafe 3-Way Locking Karabiner
The DMM Ultra D is a high-strength, versatile connector designed for demanding professional work at height. Similar in size to the Ultra O but engineered with a pronounced D-shape, it directs load forces along the major axis of the karabiner, delivering maximum strength and reliability in real-world use. This makes it an excellent choice for lanyard ends, rigging systems, and a wide range of arborist, rope access and utility applications.
Built with a Locksafe triple-action gate and a snag-free clean nose, the Ultra D provides secure, predictable handling even in harsh environments. The Taperlock nose profile increases gate push-in and cross-gate strength, helping maintain safety and efficiency regardless of loading angle.
Key Features
- D-shape design increases strength by aligning loads with the spine.
- Ideal for lanyard terminations, rigging interfaces and general height-safety applications.
- Clean-nose Keylock design for snag-free connection to ropes, slings and hardware.
- Locksafe triple-action gate provides secure locking with smooth operation.
- Taperlock nose profile boosts gate integrity and cross-gate strength.
- Strong, durable construction suitable for daily professional use.
Specifications
- Gate mechanism: Locksafe (3-way auto-locking)
- Body shape: D-shaped connector
- High strength major-axis loading
- Snag-free clean nose
FAQ
Is the Ultra D suitable for use with lanyards?
Yes, its D-shape and high strength make it ideal for lanyard ends and work-positioning systems.
What makes a D-shape stronger than an oval?
The geometry forces the load towards the spine, which is the strongest part of the connector.
Does the Taperlock system really help?
Yes, it increases cross-gate and gate-push-in strength while keeping connections smooth and snag-free.
