Petzl Stop

A Petzl Stop is a descender used primarily in caving and formerly used for industrial rope access made by the French company Petzl.

Usage
The Stop is for use with single low stretch kernmantle ropes and is usually attached to the harness via a carabiner. The rope is then threaded through the cam and bobbin by undoing the safety clip and moving the swinging side plate to the side. The swinging side plate facilitates insertion and removal of the rope without the need to disconnect it from the harness, making it less likely to be dropped while inserting and removing the rope from the Stop while at height. As the Stop is a self-braking descender, an unintentional release of the handle should stop the descent, due to the asymmetric lower cam crimping the rope. This functionality safeguards the user in the event of being knocked unconscious due to a rockfall or illness, though the fine control of rate of descent should be carried out by standard method of manually controlling friction with the hand on the rope below the descender.

A simpler version of the bobbin descender, without the stop handle, is also available.

2019 Version
The Stop was updated for sale in 2019 replacing the original version. Changes to the design including updates to the handle, the bobbins and the carabiner slot. This version also saw Petzl shift the intended use of the Stop to recreational only use.
