Abstract: Disclosed is a hinged, two-wheeled device for improving the safety of an individual or object descending along a rope from an elevated position. The device includes a two-piece hinged framed held open by a torsion spring. Each part of the frame contains a wheel with a cut out/channel with a knurled surface to increase the friction between the rope and the device and to prevent the device from disengaging during use. The rope is placed between the two wheels and the handle is pulled down, clamping the device around the rope. The two wheels are connected to viscous rotary dampers that slow the speed of the wheels during descent, preventing the user/object from accelerating in a free-fall and controlling the descent rate to a relatively constant, safer speed.
