The Peakworks® CableGrab™ is a detachable sliding device that moves freely up or down hands free on the 3/8" galvanized steel cable. When the upward force is removed, the CableGrab device automatically locks at any point on the cable. The system includes a double-locking carabiner which is to be used when securing the CableGrab™ device to the climber’s full body harness.
