Petzl Croll L Chest Rope Clamp

Designed for rope ascents, the Croll L chest ascender is simple to use. The attachment holes ensure efficient positioning during ascents. Thanks to the wide rope groove, it adapts perfectly to wide diameter, swollen or rigid, ropes while limiting friction. It is compatible with ropes measuring 8 to 13mm in diameter.
