The Kordz® IR-30 brass tube is the best all round custom installation target. Mount in a 1/2" hole in virtually any surface (as long as you have rear access), supporting panel thickness up to approx 40mm (1 1/2"). If you require a wall plate target, simply obtain a blank plate in your preferred style and drill a 1/2" hole in which to mount the IR-30. The one piece brass tube construction provides natural shielding and a totally robust housing for unrivalled longevity.
