Petzl CROLL® Chest Ascender

Designed for rope ascents, the Petzl CROLL® S and CROLL® L Chest Ascenders are lightweight and simple to use. They are used along with the BASIC Ascender or the ASCENSION Handled Ascender for rope ascents. The attachment holes ensure efficient positioning during ascents while the stainless steel wear plate improves durability by reinforcing the rope friction zone. The CROLL® S is compatible with ropes measuring 0.31'' to 0.43'' in diameter. The CROLL® L is compatible with ropes measuring 0.31'' to 0.51'' in diameter. Thanks to its wide rope groove, the CROLL® L adapts perfectly to wide diameter, swollen or rigid ropes while limiting friction.
