Vertical caving terminology and methods > Personal SRT gear
An ascender that is set up and connected in exactly the same way as a top jammer, except that the footloop is only long enough to allow the ascender to reach the top of your thigh. A safety cord is used to connect the ascender to the D-ring. Handled ascenders are preferred, as they allow the ascender to be pulled up much more easily. Used as one of the main ascenders when using the Texas system, singe system, Pygmy system (or the equivalent using a prusik loop for the Gérard Alpine technique), Plummer system and the Mitchell system. Allows feet to be used independently in step systems. It is pulled upwards by one hand, so designs with a large pulling loop at the top are generally preferred. Makes it a little awkward to pass deviations and rebelays because it is so far from your hands.
