The JBL MTC-426MR is a six-pack of optional mud ring brackets designed to simplify the installation of compatible JBL Control ceiling loudspeakers in sheetrock or gypsum board. The brackets help establish accurate speaker locations before the ceiling material is installed.

Each bracket features a circular offset that acts as an edge guide for plastering around the speaker opening. This helps create a clean, seamless finish when the sheetrock is completed.

The brackets can also be used to secure wiring behind the ceiling and serve as convenient cutout templates for multiple installations. Integrated wings allow the brackets to attach to the building structure.
