The BE One Screw from Beal is a compact carabiner with a screw lock, specifically designed for securing with single ropes and belay devices. The surface of the screw carabiner has been optimized with its cylindrical shape and 12 mm diameter for the rope, reducing wear on the rope during lowering in toprope due to the large bending radius. Additionally, the BE One Screw allows for easier rope feeding when belaying the lead climber.
