JBL MTC-447MR Mud/Plaster Ring Construction Bracket for Control 418C/T, 447C/T, and 447LP Ceiling Speakers, 6-Pack, (JBL-MTC-447MR)

JBL MTC-447MR Mud/Plaster Ring Construction Bracket for Control 418C/T, 447C/T, and 447LP Ceiling Speakers, 6-Pack (JBL-MTC-447MR)

The JBL MTC-447MR is a professional mud/plaster ring construction bracket designed to simplify rough-in installation of selected JBL Control Series ceiling loudspeakers. Intended for use during the pre-construction phase, this accessory helps installers accurately define loudspeaker locations before drywall or gypsum board ceilings are installed, ensuring clean and consistent installation results.

Compatible with the JBL Control 418C/T, Control 447C/T, and Control 447LP ceiling loudspeakers, the MTC-447MR provides a convenient method for reserving speaker locations and preparing ceiling cutouts before ceiling finishing work begins. It is especially useful in commercial installations where multiple loudspeaker locations must be established efficiently and accurately.

The bracket features a circular offset plaster ring that serves as an edge guide for drywall finishing and speaker cutout preparation. Once mounted to ceiling support structures, installers can use the outer ring as a cutting template for sheetrock openings. The drywall is then finished directly to the edge of the ring, creating a clean, professional loudspeaker cutout.

In addition to functioning as a cutout template, the MTC-447MR allows speaker wiring to be secured behind the ceiling before drywall installation. This improves cable management, reduces installation time, and helps streamline large distributed audio projects. The bracket can also serve as a location reservation device to ensure speaker positions remain accurately defined throughout the construction process.

Constructed from durable metal materials, the MTC-447MR is engineered for professional commercial audio installations and attaches directly to building support structures. It is particularly beneficial in production-style installations where many speaker openings must be created consistently across a project.

Supplied as a 6-pack, the JBL MTC-447MR is ideal for hospitality venues, corporate offices, educational facilities, retail environments, healthcare institutions, houses of worship, entertainment spaces, and professional AV installations.
