Abstract
A device for providing a controlled maximum rate of descent down a rope and fall arrest. The device includes a movable cam that in response to tension on a rope pivots into a closed position, jamming the rope within the device and arresting a fall. Force applied to a torque arm coupled to the cam allows the cam to be pivoted to its open position, which allows rope travel. As cam is opened, the rope travels a more sharply angular path through the device, which creates a frictional force on the rope sufficient to limit the maximum rate of descent.
