JBL MTC-426MR Mud/Plaster Ring Construction Bracket for Control 416C/T, 416C/T-VA, 426C/T, 426C/T-LS, and 445C/T Ceiling Speakers, 6-Pack (JBL-MTC-426MR)

The JBL MTC-426MR is a professional mud/plaster ring construction bracket designed to simplify the rough-in installation of compatible JBL Control Series ceiling loudspeakers. Intended for use during the pre-construction phase, this accessory helps installers accurately define speaker locations before drywall or gypsum board ceilings are installed, improving installation efficiency and consistency.

Compatible with JBL Control 416C/T, 416C/T-VA, 426C/T, 426C/T-LS, and 445C/T ceiling loudspeakers, the MTC-426MR provides a reliable method for reserving speaker positions and preparing ceiling cutouts during construction. It is particularly useful in commercial projects where multiple loudspeaker locations must be established before ceiling finishing work begins.

The bracket features a circular offset plaster ring that serves as an edge guide for drywall finishing and plaster work. Once mounted to the building structure, installers can use the ring as a cutout reference, allowing sheetrock to be cut and finished neatly around the speaker opening for a clean, professional appearance.

In addition to acting as a cutout template, the MTC-426MR provides a convenient point for securing loudspeaker wiring behind the ceiling before drywall installation. This helps streamline cable management and reduces installation time, especially in large-scale distributed audio projects.

The bracket includes mounting wings that attach directly to ceiling support structures, ensuring accurate placement and long-term installation stability throughout the construction process. It is particularly beneficial for production-style installations where multiple speaker openings must be created efficiently and consistently.

Supplied as a 6-pack, the JBL MTC-426MR is ideal for commercial audio systems installed in offices, hospitality venues, retail spaces, educational facilities, healthcare environments, houses of worship, and professional AV projects.
