Product information & specifications
Petzl AM'D Triact-Lock D Shape Carabiner
The Petzl AM'D Triact-Lock is a lightweight, asymmetrical aluminium carabiner with a D shape designed for connecting a belay system or holding gear such as descenders and positioning lanyards. The TRIACT-LOCK automatic locking system uses a triple-action gate opening, giving reliable, secure locking without needing to manually engage a screw gate.
The D shape and ergonomic profile make it easy to handle and grip, even while wearing gloves. A fluid interior design limits catch points and aids smooth rotation, while the Keylock system prevents the carabiner from snagging during use. The H-profile cross-section gives an improved strength-to-weight ratio and protects the printed markings from abrasion.

Why Choose the AM'D Triact-Lock?
The D shape is genuinely purpose-built for connecting equipment like descenders or positioning lanyards, rather than a general-purpose oval — it holds these devices more securely in position. TRIACT-LOCK's automatic triple-action gate means you're not relying on remembering to manually screw a gate closed under pressure, which matters when reconnecting quickly at height.
