Lightweight hot forged alloy HMS screw-in carabiner with ACL system. Designed for alpinism, traditional and sport climbing. Especially suitable for use with belay devices. The wider side of the carabiner provides ample room for belaying through a half-boat knot or for rope maneuvers at the belay station. It has an accentuated double-T profile for an excellent weight/load ratio. The carabiner is lightweight and contoured for a better grip. Carabiner nose has no beak to prevent snagging when snapping in and out. ACL system - a steel loop that allows the carabiner to be clipped into the belay eye of the saddle, which fixes its position and prevents cross loading of the carabiner.
