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!
