JBL MTC-424MR Mud/Plaster Ring Construction Bracket for Control 412C/T, 412C/T-VA, 414C/T, 414C/T-VA, and 424C/T Ceiling Speakers, 6-Pack (JBL-MTC-424MR)

The JBL MTC-424MR is a professional mud/plaster ring construction bracket designed to simplify the rough-in installation of JBL Control Series ceiling loudspeakers in sheetrock and gypsum board ceilings. It serves as a pre-installation mounting aid, helping contractors and AV installers accurately position speaker locations before ceiling finishing work is completed.

Compatible with the JBL Control 412C/T, Control 412C/T-VA, Control 414C/T, Control 414C/T-VA, Control 414MC/T, and Control 424C/T ceiling loudspeakers, the MTC-424MR provides a reliable method for reserving speaker locations during new construction and renovation projects.

The bracket features a circular offset plaster ring that acts as an edge guide for drywall finishing and plaster work. Once attached to the building structure, installers can use the ring as a template for cutting speaker openings and creating clean, professional ceiling cutouts. This helps ensure accurate speaker placement and improves installation consistency across multiple loudspeaker locations.

In addition to functioning as a cutout guide, the MTC-424MR allows wiring to be secured behind the ceiling before drywall installation. This simplifies cable management and helps streamline large-scale distributed audio projects where multiple speaker locations must be prepared in advance.

The bracket is especially useful in production-style installations where many ceiling cutouts are required, helping improve efficiency and reduce installation time. Its winged design attaches directly to ceiling support structures to provide a stable reference point throughout the construction process.

Supplied as a 6-pack, the JBL MTC-424MR is ideal for commercial installations in offices, retail stores, hospitality venues, educational facilities, healthcare environments, houses of worship, and professional AV systems.
