DMM Shadow HMS Locksafe

HMS stands for 'Halbmastwurfsicherung,' which is German for 'half-clove hitch belay.' It indicates the carabiner has a pear shape, designed specifically to accommodate the friction and movement of a Munter hitch or other belay devices.

The Locksafe mechanism is a triple-action auto-locking gate. You must lift, twist, and push to open it, ensuring it automatically locks shut the moment you release the gate.

The short gate design allows for a wider gate opening relative to the size of the carabiner. This makes clipping ropes or anchor points significantly easier, especially when you are wearing gloves or working in a hurry.

While the specifications note compatibility for ropes under 9.5mm, this refers to the optimal performance range for specific belay devices or friction hitches. The carabiner itself is large enough to handle standard climbing ropes, but you should always check the compatibility of your specific belay device first.

Yes, it is excellent for anchors. The deep, wide basket is specifically engineered to hold multiple clove hitches or several slings without crowding the gate, keeping your master point organized and easy to inspect.
