The JA71-xxx series of Ventilated Dzus Mount Blanking Plates allows cooling air to be circulated within the avionics equipment console. The offset ventilation holes keep foreign object debris (FOD) from entering behind the control panel while allowing the free passage of air. The matching design and colour to existing control heads present a professional look and feel to the instrument panel.

The JA71-Vxx series are painted with a baked-on flat black (or gray) urethane finish to resist scratches and nicks. The JA71-Vxx is available in a series of different Dzus hole sizes.
