The AB-20 is a simple yet versatile rope clamp to be used in many different setups. Its basic field of work is as a general purpose rope clamp to be used in various rope access and rescue manoeuvres.

Modern ascending techniques, however, give it value as a hand ascender and the webbing slot at the bottom of the device enables it to be stitched into the harness and used as a chest ascender.

The AB-20 is certified according to the European standards EN 567 for sport use and EN 12841 type B for work at height use. According to the first standard it is tested to work with low stretch and dynamic ropes from 9 mm to 13 mm and according to second with type A low stretch ropes from 9 mm to 13 mm.
