The Atlas Sound MPFD12-3 vented rack door is designed for use on the WMA series wall mount cabinets. The MPFD series combines the benefits of vented cooling with the ability to see LED's, TFT's or CRT's housed in the rack via the integral perforated steel mesh panel. A 16GA metal door frame provides exceptional strength to the door assembly. The extended 3-inch depth allow the installer to position rack rails to the front face of the WMA cabinet and still have adequate clearance for rack handles or security covers that might be installed on the rack mount equipment.
