Ascenders come in a variety of different shapes and sizes and are designed to allow the user to ascend a rope or wire. The traditional hand ascenders / Jammers normally have toothed cams which lock on to a rope when the device is loaded but unlock when the device is unweighted and pushed upwards. An ascender can also be known as a jumar.
