The JBL MTC-24TR Trim Ring is a white, steel trim ring designed specifically for retrofit installations of JBL Control 24C and Control 24CT ceiling speakers into existing ceiling cutouts that are larger than the speakers' standard size. This trim ring serves as a solution for achieving a clean and professional finish when installing JBL Control 24C/CT speakers into oversized pre-existing ceiling openings. It conceals any gaps around the speaker, enhancing the aesthetic integration of the speaker with the ceiling environment and providing a secure mounting solution without requiring extensive ceiling repair.
