Edelrid HMS Bulletproof Screw FG Locking Carabiner

The steel insert is located at the rope-bearing point, which is where most friction occurs during belaying and rappelling. This reinforcement significantly slows down the wear and tear typically seen on aluminum carabiners, giving the gear a much longer lifespan.

The integrated spring bar is designed to hold the carabiner in the correct orientation on your belay loop. This prevents the carabiner from rotating or cross-loading, which is crucial for maintaining safety and proper strength during use.

Yes, the screw-gate is straightforward and reliable, though it does require manual locking. It is generally easy to operate, even with gloves, but it lacks the automatic locking convenience found on some other models.

Absolutely. The HMS shape is specifically designed to accommodate a Munter hitch, providing smooth rope handling and consistent friction control during belaying or rappelling.

Yes, it features a keylock nose design. This prevents the carabiner from snagging on your rope, harness, or gear loops when you are clipping or unclipping.
