A multi-purpose, compact ascender, the Petzl BASIC is super lightweight and offers excellent grip for rope ascents. Can be used for rope ascent on a fixed line or as progress capture in a hauling system. Toothed cam with self-cleaning slot optimizes performance under any conditions (like dirty or frozen ropes). Stainless steel cam offers better resistance to corrosion. Lower attachment hole is large enough for both the lanyard and foot loop carabiners. Upper connection hole helps guide the rope. Made for use with single ropes between 8 and 11 mm. 3342540094314 20074300012 B18BAA
