I’D S is a self-braking descender with an ergonomic handle that allows control of the descent speed and fluid movement along inclined or horizontal terrain. The integrated anti-panic function and anti-error catch limit the risk of an accident due to user error. The AUTO-LOCK system allows users to easily position themselves at a workstation without having to manipulate the handle or tie off the device. Once locked, the rope can be taken up without having to manipulate the handle. The safety clip reduces the risk of dropping the device and facilitates passing of intermediate anchors. I’D S is compatible with 10 to 11.5 mm ropes and allows handling of loads up to 250 kg.
