Descenders with a self-braking feature and multi-functional handle allow the user to control the descent and to get into position without having to tie off the device. These devices are primarily designed for difficult to access work sites and rescue: for positioning at a work station or for movement along low-angle or horizontal terrain. The I’D S and I’D L descenders have an integrated anti-panic function and an anti-error catch. The RIG descender is designed for expert users.
