The MBD001 is a DIN mounting adaptor for the TX3200, TX3220, TX3400, tx3420, TX3440, TX3600, TX3500, TX3510, TX3520 & TX3540 series transceiver. 

It allows the CB to be fitted into the DIN aperture of a vehicle dash. (Same size hole as a car radio cassette). The bracket has been designed to facilitate as many vehicles and mounting positions as possible with the use of slots in the horizontal and vertical plane. The front escutcheon has an aperture to allow the sound from the internal speaker to project forward and in many vehicles an extension speaker will not be necessary.
