What is an Ascender? An ascender is a mechanical device used for ascending on a rope. One such device is a Jumar, named after the Swiss factory 'Jümar'. The device's name also leads to the term Jumaring for the process of using an ascending device. Other terms for this process include ascending, prusiking and jugging.
