Abstract
A descent control device is disclosed manufactured with a bar having holes for guiding a rope used in descent, and a lever designed to pivot or move relative to the bar and compress the opening of one of the holes. Compressing the opening increases friction and slows or stops descent. Control can be from manually moving the lever or by connecting the lever to the descending weight, thereby automatically moving the lever. Hole and pivot geometry may be altered to provide multiple braking options, accommodate varying ropes, and alter normal operating friction.
