DMM Shadow Locksafe Carabiner

The Triact-lock is a triple-action gate mechanism. To open it, you must perform three distinct movements: slide the gate sleeve up, twist it, and then push the gate open. This design is significantly more secure than a standard screw-gate, as it prevents accidental opening while remaining easy to operate with one hand.

The D-shape is specifically engineered to transfer the majority of the load onto the carabiner's spine, which is its strongest axis. This makes it an excellent choice for belay setups and general utility where you want to maximize strength-to-weight efficiency, though it offers less internal working space than a pear-shaped HMS carabiner.

You shouldn't. The carabiner features a generous 17mm gate opening designed specifically to accommodate gloved hands. Combined with the snag-free nose geometry, it remains easy to manipulate even in cold, bulky gear.

The I-Beam construction allows DMM to remove excess material from non-load-bearing areas of the carabiner without compromising its structural integrity. This results in a lighter overall weight of 58g while maintaining a high major axis strength of 24 kN.

Yes, the keylock nose design eliminates the traditional 'hook' found on older carabiners that often catches on rope, slings, or bolt hangers. It creates a smooth, flush surface that allows for clean clipping and unclipping, which is essential for efficiency on technical routes.
