The Camp HMS Nitro Lock Carabiner is one of the lightest locking carabiners in the world! The HMS Nitro Lock from Camp features a new rounded body shape and thinner gate. The carabiner has been designed to maximize both safety and performance. The new design offers an optimal area for working with the Italian hitch knot (HMS) and increases the strength in gate-open and minor axis positions. I-Beam construction delivers a high strength-to-weight ratio while still maintaining a rope friendly radius.
