The Petzl Croll is a caving ascender designed for climbing a single rope.

The Croll's flat shape lies against the body. It joins a sit harness to a chest harness, holding a caver into the rope. The advantage of this is that the Croll slides up the rope very easily.

Warning:
This ascender is not designed to be used as a self-belay device

Features:
Chrome-plated steel cam has inclined teeth and self-cleaning slots to provide grip on wet, icy or muddy ropes.
Ergonomic spring-loaded catch allows the cam to be held in the open position and facilitates one-handed installation or removal of the device.
Angled attachment hole and special shape allow device to remain flat against the stomach. Rectangular upper hole for attachment of shoulder straps to position the Croll correctly.
The Croll slides up the rope easily as the user ascends.
