The choice of daredevils and climbers the world over, the Petzl AM’D Locking Carabiners are the most versatile and reliable of their kind. With three lock modes – Screw-Lock, Triact-Lock and Ball-Lock – they’re perfect for pretty much every situation and the keylock gate prevents snagging when you’re building an anchor, which is quite handy when you’re half-way up a cliff-face.
