The D1PRO Descender uses our patented D-Series progressive cam technology and a specifically designed rope with a 6 mm diameter to achieve optimal one-handed descent control with performance characteristics comparable to a rope descender device with an 11 mm diameter.
The D1PRO Descender is a compact, lightweight device that can be stored in the user’s harness and deployed efficiently as needed. The D1PRO Descender is an auto-stop device (descent stops when the user releases the control lever). The absence of a panic brake on this ‘PRO’ model gives the user the freedom to descend without accidental activation of the panic brake. This can be useful in longer, faster descents and in emergency situations, when an efficient and uninterrupted descent is especially important.
The D1PRO ESCAPE (KT851) and D1PRO TACTICAL (KT850) descent kits have a nominal load of 140kg and are certified according to the EN341-D* standard.
