The Phantom HMS carabiner is extremely well-suited to belaying and rigging, with its perfect balance between size, strength, and weight.
An extra-short gate means it can take two clove hitches with ease, while the corners feature recesses to direct gear and rope into the right position and ensure a smooth action. The long axis is built with an I-Beam construction to reduce weight while retaining a strength of 25kN when closed.
DMM is an awesome recreational climbing and mountaineering equipment company from Llanberis North Wales. Founded in 1981 they still make and test all their gear from home.
