ALIEN REVO CAMS are 20% narrower then their classic cousins and also the narrowest and lightest in their class - thanks to patented internal cam springs and spin riveted axles construction. This super compact design allows solid installation in the tightest of slots - to increase your placement options and also number. Experienced climbers know flexible single cable cams bend in all directions equally, can be snaked into irregular cracks, plugged into horizontal placements and also maintain their position by resisting rope drag. Notice the streamlined ergonomic trigger assembly and shaped cam control wires - for longevity. For aid or use with a quickdraw, keep it simple with the standard 11mm Dyneema sling. If you wish to save a biner and runner - choose the long ALIEN REVO EXTENDABLE SLINGS. Be sure to place your ALIENS (like all cams) at 50% closure - for maximum holding strength. Made in Spain.
