Lightweight HMS carabiner with triplex twist-lock and ACL system. Hot forged from light alloy. Designed for alpinism, traditional and sport climbing. Particularly suitable for use with belay devices. The wider side of the carabiner provides ample room for belaying through a half-boat knot or for maneuvering the rope at the belay station. Highlighted double-T profile for excellent weight/load capacity 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 or a single point that fixes its position and prevents cross loading of the carabiner.
