Ascenders are a rock climbing device used by rock climbers and cavers to mechanically ascend a fixed rope. They can also be called jumars, named after a popular ascending device. Ascenders are often used during the ascent of multi pitch aid climbs, such as the big wall climbing offered in Yosemite, and they are also used to haul sacks up a climb.
Ascenders are available in several different styles ranging from a basic design for occasional use, to handled ascenders designed for multiple, all day use. Take a look at our collection below:
