Petzl Croll L

Chest-Mounted Rope Clamp

The Petzl Croll is ideal for long rope ascents, passing intermediate anchors and for transitioning from ascending to descending.  It should generally be used in conjunction with an lanyarded hand ascender (never ascend on a single point of contact with the rope).

Features of the Petzl Croll L include:
  • trigger cam with self -cleaning slot: works even on dirty ropes
  • catch is opened by pinching which gives quick and easy installation/removal of rope when the device is in place on chest
  • spring-loaded catch can be locked in the open position so the rope clamp can be put on or taken off the rope with one hand
  • the attachment hole is oriented so the device lies flat against the chest when clipped in
  • compatible with ropes measuring 8 to 13mm diameter
  • mounts easily on harnesses such as the CMC Helix.
