The Radion is the most advanced ice screw available. A unique hanger rotates independently on the shaft, ensuring the force of a fall is applied at the optimal angle. The Radion features a reverse angle on the threads (flat side towards the ice), to distribute pressure more uniformly in brittle ice. Placing a Radion is greatly simplified by the aggressive front teeth, an ultra-smooth shaft, and a stiff lever arm with a rotating knob. The 12-mm color-coded Dyneema sling saves the weight and hassle of an extra draw. With a carabiner pre-attached you can be moving upwards faster than ever. The screw can be placed or removed while clipped to the rope ensuring it will never get dropped. A carabiner hole on the steel hanger gives a second option for racking.
