The ATC-XP is variable friction belay/rappel devices designed specifically for belaying and rappelling during climbing and mountaineering. The ATC has a high-friction mode (HFM) and a regular-friction mode (RFM), giving one the ability to select the appropriate level of friction for the specific belay or rappel situation. In the HFM, the ATC-XP and have two to three times the friction of the device when used in the RFM. Use the ATC-XP in the HFM when you want more holding power—typically when using small diameter ropes, when rappelling a single line or when belaying a climber working a route. Use the ATC-XP in the RFM when you don’t need the extra holding power.
