Petzl Croll Rope Access Chest Ascender

The Petzl Croll

The Croll chest ascender is another rope access and Rescue staple from Petzl.  The name Croll is used as a term for all chest ascenders.  It has become more compact over the years and the latest version finds a stainless steel liner in the rope channel for greater strength and durability.

Apart from being a great chest ascender for any rope access or rescue harness, the Croll works very well as rope grab in hauling systems.  Just remember not to shock load it!
