Petzl Croll Compact Chest Ascender

The CROLL chest ascender is unmatched for efficiency on fixed lines. Compact and lightweight, it does not interfere with progression. The stainless steel wear plate improves durability by reinforcing the rope friction zone. It is used with a BASIC ascender or with an ASCENSION handled ascender for rope ascents. The toothed cam with self-cleaning slot optimizes performance under any conditions (e.g. frozen or dirty ropes). Stainless steel cam has better resistance to corrosion. Stainless steel wear plate makes for improved durability. Open the catch by pinching for simple, quick manipulation that you'd expect from Petzl. The lower hole is angled to keep the CROLL chest ascender flat. The upper hole is for attaching a TORSE shoulder strap and keeping the ascender in position.
