The König & Meyer 23855 is a black steel table flange - a screw-on mounting base that lets you fix a K&M microphone desk arm permanently to a desk, lectern, broadcast table or studio worktop. K&M specifies it for its 23850 and 23860 microphone arms, which slot into the upright socket and are held by the knurled K&M thumbscrew, so the arm can still be rotated or lifted out when needed. The round base is 73 mm in diameter and is fixed down with three screws through its 5.2 mm bore holes, giving a neat, stable anchor that does not take up desk space the way a clamp or weighted base does. Overall height is 61 mm and it weighs 0.24 kg. Typical installations are radio and podcast studios, council chambers, lecture theatres, conference rooms, churches and call centres. This is order number 23855-000-55, the black version (EAN 4016842216512), made by König & Meyer in Germany. Mounting screws for your desk are not specified by K&M.
