MTC-424SG 6-Pack

The MTC-424SG is a 6-pack of full-face, square white magnetic grilles made for JBL Control 424C/T ceiling speakers, giving a full zone of 4" speakers a matching architectural look in one order. The square profile lines up with ceiling tile grids, square light fixtures, and air diffusers, so a round speaker cutout reads as a deliberate part of the ceiling plan instead of an afterthought. The signal white (RAL9003) finish matches the stock Control 424C/T grille and blends into the light-colored ceilings common in offices, conference rooms, classrooms, retail floors, restaurants, and hotel lobbies.

Each grille holds on magnetically, so it goes up fast during installation and lifts off by hand when you need to reach a transformer tap or check a driver. A safety tether mounts right into the speaker baffle and keeps the grille connected while it is off, so nothing drops onto desks, displays, or guests below. With six grilles in the box, you can outfit three pairs of Control 424C/T speakers at once, switch an existing install from round to square, or keep spares on hand for damaged or missing grilles.
