When it comes to ascending fixed lines, nothing rivals the Petzl Croll Chest Ascender for speed and efficiency. When used in conjunction with a chest strap (Petzl Torse) and a basic handled ascender, the Croll simply slides up the rope as you make upward progress. The self-cleaning slot allows the stainless steel cam to perform on frozen or dirty ropes, and the compact nylon trigger allows for quick manipulation of the device.

Weight: 90 g. Rope: for use with single ropes between 8 and 11 mm. Certification(s): CE EN 567, UIAA?. Open the catch by pinching for simple, quick manipulation. Lower hole angled to keep the CROLL chest ascender flat. Upper hole for attaching a TORSE shoulder strap and keeping the ascender in position. Stainless steel cam has better resistance to corrosion. Stainless steel wear plate for improved durability. Toothed cam with self-cleaning slot optimizes performance under any conditions (e.g. frozen or dirty ropes). Used with a BASIC ascender or with an ASCENSION handled ascender for rope ascents.
