The Mammut Bionic HMS Carabiner is a locking carabiner for use while belaying. A large curve at the top offers up plenty of room for the rope, while the smaller bottom curve allows you to handle with one hand. Open the gate by un-screwing the lock, and locking it by screwing the opposite way.

The Mammut Bionic HMS Carabiner will exceed your expectations no matter what you're climbing whether it's rock, ice, or somewhere in between. Beam technology uses a special high-precision hot forging method that keeps this biner surprisingly light for how strong it is. A twistlock gate makes sure your belay is always locked, and a keylock nose lets you unclip ropes and your belay devices without a hassle. Mammut designed the Bionic with a large arc radius that accommodates any safety device or knot without any bulking.
