The PM-3TG is a tray that mounts above a projector using a standard (1.5" I.D.) round projector pole or any smaller round or rectangular pole. The tray accommodates any RU, TX, FP or STICK-ON Audio Power Amplifier and its associated RDL power supply. The unique design of the PM-3T permits installation above a projector without removing the projector or pole. The durable steel tray is constructed in two pieces to slide over the projector pole from each side, making installation fast and convenient. The PM-3T is available in three colors. The standard color is black (PM-3T). It is also available in white (PM-3TW) and gray (PM-3TG).
