A compact descender apparatus which is easy to use and easy to store for lowering a person from an elevated position to a relatively lower position, having a generally cylindrical housing; a spool mounted for rotation in the housing having an axis of rotation which is in orthogonal relationship to a front face of the housing; a rope stored on the spool having a free end portion which extends upwardly to a helical groove on an outer portion of a friction core which is mounted on an upper portion of said housing for controlling a rate of descent with the descender; and a camshaft rotatably mounted in the housing for adjusting the rate of descent. A tang extending downwardly from a lower portion of the housing and a pair of spaced apart bosses having apertures on an upper portion of said housing are provided for attaching the descender apparatus.
