Abstract: The clamp/door stop device comprises an elongate frame including an elongate base with first and second feet each mounted at one end of the base. The feet rest on a planar supporting surface such as a floor. The platform on the base has a planar rest, and a frame portion extends upwardly from the platform and has a planar surface generally perpendicular to the plane of the planar rest. A clamping mechanism for clamping a portion of a door or like object against the planar surface with the object abutting the planar rest are provided. A rod is mounted on the base for sliding movement relative to and transversely of the base in a direction generally parallel to the planar surface and generally 90.degree. to an elongate axis of the elongate frame. A third foot is provided at one end of the rod and is movable with the rod between an extended position and a retracted position. A biasing spring is mounted on the rod at one end of the rod.
