ABSTRACT:
A portable assembly comprising a nylon flame retardant support rope, an adjustable size waist band and crotch harness and a lever controlled brake rope friction device. The user securely fastens the rope at the point of departure, threads the rope through the friction device and fastens the device to the harness. The lever on the friction device regulates the rate of descent from a full stop to the limiting rate prescribed by the friction ring assembly. Alternately, the user may hand hold the friction device for lowering a load fastened to the harness.
