ISC D4 Descender Black
Limited stock available please contact us for large orders - Does not include the karabiner! (sold seperately)
The D4 Descender features a unique and innovative progressive cam action, which offers precise control at slow or fast speed. The device 'fails to safe' (the device locks if the handle is released) and also has a panic brake feature (if the handle is pulled down in panic when in freefall then it locks the device - The progressive cam design means that this panic brake is not overly sensitive in normal use).
The device is made from a high grade aluminium and has a stainless steel cam, axles and top bobbin which should ensure a good degree of longevity. The beauty is that the internal workings are cleanable.
