Description The Black Diamond® Express Ice Screw features a unique tapered tube where the teeth cut a hole just larger than the tube itself for less friction during placements. A large, color-coded crank knob design requires less fine motor skills and makes for easy size identification with an uninterrupted 360-degree motion allowing for incredibly fast placements. Black Diamond® uses a stainless steel hanger aid in the reduction of sun-induced melt out while eliminating rusting. Having two carabiner holes allows for an easy set up when hanging sketchy belays. Recommended for use in ice, alpine and mixed climbing environments.
