JBL MTC-48TRX12 4' x 4' Ceiling Tile Track

JBL Professional MTC-48TRx12 - 4'x4' (1200x1200 mm) Ceiling Tile Rails for JBL Ceiling Speakers

The JBL Professional MTC-48TRx12 is a tile rail set designed to securely mount numerous JBL ceiling loudspeakers into 4' × 4' (1200 × 1200 mm) drop ceiling modules. These rails work with JBL’s C-ring/tile rail mounting system , providing the extra rigidity required for the 1200 mm span and reducing vibration and rattles with the inverted V-groove , which also supports the grid in the event of tile failure.

Each rail is made from 1.2mm (18 gauge) SECC galvanized steel and offers multiple C-ring attachment points, allowing the mount to be tailored to the model and site conditions. The package includes 12 rails , enough for 6 speakers (2 per speaker), optimizing costs and logistics for medium- to large-scale projects.

Compatibility

Fits any JBL in-ceiling speaker that uses C-ring/tile rail . Models included (at product launch): Control 24C/CT Micro and 24CT MicroPlus; Control 24C/CT; Control 26C/26CT; Control 19CS/CST; Control 47C/T, 47LP, 47HC, 40CS/T, 42C; Control 226C/T; 8124/8128 . Not compatible with speakers that are installed with a tile bridge (e.g., CSS Series, 8138, C227C/CT, C300 Series ).

Main features

• Advanced Support Design: Inverted V-groove supports the grid if the tile fails and minimizes vibration transfer to the ceiling system.
• Robust structure: 1.2 mm (18 gauge) SECC galvanized steel provides the necessary strength for the large span of 1200 mm.
• Mounting versatility: 30 holes for C-ring fixing and additional positions drillable by the installer if required.
• Project pack: 12 rails per box → 6 speakers (2 rails per speaker).
• Wide Compatibility: Works with all JBL ceiling mounts that use a C-ring/tile-rail ; model list included and upgradeable.

Product benefits

• Safety and compliance: mechanical reinforcement suitable for 1200x1200 mm modules, reducing the risk of the plate buckling.
• Less parasitic noise: The V-profile reduces rattling and vibrations in the roof grid.
• Agile installation: multiple pre-drilled holes and the possibility of adding new points as needed.
• Stock optimization: a single package covers six points, simplifying purchasing and logistics.

Use cases

• Shopping centers, supermarkets and retail with 1200x1200 mm modular ceilings.
• Hotels, restaurants, convention centers, and offices with built-in BGM/PA systems.
• Educational centers, healthcare facilities, and public buildings with stable and quiet installation requirements.

Dimensions and construction

• Rail Dimensions (H × W × L): 27 mm × 30 mm × 1267 mm (49.9 in total length).
• Separation between vertices of the inverted “V”: 1219 mm (48.0 in) to align with the roof grid.
• Material: SECC galvanized steel, thickness 1.2 mm (0.05 in, 18 gauge).
• C-Ring Holes: 30 (evenly spaced from axis), with additional drillable locations.
