DMM Sentinel HMS Locksafe

1   |  

The DMM Sentinel HMS Locksafe is an eye-catching and rather unusually shaped stand out climbing carabiner. 

Far more to it than mere cosmetic appeal however, the DMM Sentinel is not only a very neat and light belay carabiner, but also one that's loaded with several interesting design features. The kink in the spine has real functional advantages. For a start it allows for a bigger gate opening and makes it easier to handle, and it also encourages the biner to stay correctly aligned on your harness belay loop.

The DMM Sentinel HMS is versatile enough to make a good rigging biner too. You can fit a couple of clove hitches on it; plus it has a slightly offset shape that increases strength by directing force into the spine of the biner.

Locksafe Mechanism
This clever triple-action, locking mechanism is almost as simple to use as the original spring-loaded 'Kwiklock' mechanisms, requiring just one extra push-up action of the barrel before the twist. This extra dynamic (level of safety) means the biner provides far better protection against accidental opening.
