This plastic microphone and speaker cover is designed for the TYT MD-390. To ensure waterproof capabilities, the handset must have the side mic/spkr cover in place to protect the internal parts of the radio and to prevent water ingress.
This part comes with the speaker / mic cover itself. A rubber gromit which fits into the speaker mic cover plus the locking / fixing screw which attaches into the side of the radio.
If you need a replacement or keen to have a spare for your programming cable or an earpiece, the fixing screw alone is a sort after part.
This part also fits the Retevis RT8 Two way radio.
