This is the third incarnation of the Croll in just over 20 years and it's now much smaller and more durable.
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.
Used with a BASIC ascender or with an ASCENSION handled ascender for rope ascents
Toothed cam with self-cleaning slot optimizes performance under any conditions (frozen or muddy ropes...)
Stainless steel cam has better resistance to corrosion
Stainless steel wear plate for improved durability
Catch is opened by pinching for simple, quick manipulation
Lower hole angled to keep the CROLL chest ascender flat
Upper hole for attaching a TORSE shoulder strap to keep the rope clamp in position
Available in two versions: - CROLL S: (11mm rope max) compact and lightweight rope clamp. This version has a rope channel that is reinforced with stainless steel, for very harsh environments - CROLL L: (13mm rope max) rope clamp with wide rope channel for excellent fluidity during ascents
