Edelrid's Elevator Ascender isn't as easy as pressing a button to go up a skyscraper, but it's the next best thing, and a big mountain beats elevator music every time. Edelrid did make this ascender as efficient and convenient as possible though. There are three attachment moisture for different styles of ascending, and both left- and right-hand models are in different colors for easy identification on the climb. Edelrid optimized the cam for gripping icy, muddy ropes for extra security in the alpine or on mountaineering missions.
