With multiple friction modes and a versatile design that's ideal for any climbing situation, the Black Diamond ATC-XP is the evolution of our classic Air Traffic Controller. The ATC-XP's grooved high-friction mode offers three times greater hold and stopping power, while its geometric, fluid design reduces rope kinks when lowering your partner.  And with its wide range of rope compatibility (from 7.7 mm to 11 mm), the ATC-XP is perfect for everything from sport cragging to alpine ice.
