Petzl Am'D Carabiner

The asymmetrical D-shape is specifically engineered to make connecting equipment like descenders or positioning lanyards more efficient. Its geometry directs the load toward the carabiner's strongest point, the major axis, ensuring your gear stays properly aligned during use.

Yes, it makes a significant difference. The Keylock system removes the small hook found on traditional carabiners, which prevents the gate from snagging on ropes, slings, or your harness gear loops while clipping and unclipping.

Absolutely. The Am'D is designed to be compatible with positioning bars, which are highly recommended if you want to ensure the carabiner remains loaded along its major axis and prevents it from flipping or cross-loading.

The H-shaped cross-section is a clever design choice that allows Petzl to reduce the overall weight of the carabiner to just 75 grams without sacrificing strength. It also serves a practical purpose by protecting the carabiner's markings from abrasion, keeping them readable over the life of the product.

The choice depends on your specific application. SCREW-LOCK is best for occasional use where you want a simple, manual check; BALL-LOCK is ideal for frequent opening and closing with a visual indicator that it is locked; and TRIACT-LOCK is the most secure option for high-intensity work where automatic locking is essential for safety.
