This versatile lightweight belaying & abseiling device is now 30% lighter than the original ATC (Air Traffic Controller) thanks to enhanced construction & cut outs in the sides. The variable friction modes allow a wide range of rope diameters from 7.7 to 11mm & the high friction mode is especially useful in desperate situations or when belaying heavier partners. The stiff cable keeps the ATC XP where it should be & avoids rope tangling making this slick device completely intuitive to use. 30% lighter than the original High-friction mode offers 3 times greater hold & stopping power than regular-friction mode Machined windows through device for weight savings Durable cable holds its shape & resists getting caught up between ropes Hot-forged construction Versatile design accepts ropes from 7.7 to 11 mm
