Add or convert your existing din-style marine radio to a round gauge-style aftermarket radio with this Replacement Trim Plate for Most 3" Marine Radios by Stinger. This universal dash kit features eight independent mounting configurations for boats with single-DIN rectangle, double-DIN or oversized splash protector openings so you can add or upgrade your marine radio without making additional modifications to the console. The SEADASH3B also features OEM-grade ASTM-G154-16 certified UV-protected ABS, no-fade ASA plastic, and stainless hardware to protect against the elements, shocks, scratches and more.
