Edelrid HMS Strike Locking Carabiner

The wire bracket acts as a keeper to hold the carabiner in the correct orientation on your belay loop. This prevents the carabiner from cross-loading or twisting, which is critical for safety when belaying.

The triple lock requires a specific sequence—slide, twist, and open—which adds a layer of security compared to a screw-gate. While it takes a fraction of a second longer to operate, it becomes intuitive with practice and is significantly more secure against accidental opening.

Aluminum carabiners can develop sharp grooves over time due to rope friction, which can damage your rope. The steel insert is much harder than aluminum, significantly extending the lifespan of the carabiner and protecting your rope from premature wear.

Yes, the HMS shape is designed to be versatile and works well with most standard belay devices, including tube-style devices and assisted-braking devices. Its shape is specifically optimized to keep the device properly positioned.

The H-profile design allows Edelrid to remove excess material from non-load-bearing areas while maintaining high structural strength. This results in a lighter carabiner that doesn't compromise on safety or durability.
