Tile Rail for 4' x 4' Ceiling Tiles

MTC-48TRx12 is an accessory tile rail for installing many of JBL’s ceiling loudspeakers into 4 ft by 4 ft
(1200 x 1200 mm; 48 x 48 inch) ceiling tiles in suspended ceiling applications.

  • Can be used with any JBL ceiling speakers having the C-ring/tile-rail mounting system.
    Includes (at product release):
    • Control 24C/CT Micro & 24CT MicroPlus
    • Control 24C/CT, 26C/CT, 19CS/CST
    • Control 47C/T, 47LP, 47HC, 40CS/T, 42C
    • Control 226C/T
    • 8124/8128
    • Not for JBL speakers that install with tile bridges (such as CSS Series, 8138, C227C/CT, C300 Series models). Check with JBL Professional Customer Service for most up-to-date compatibility list.
  • Inverted V-groove provides support to the tile rail grid in case of tile failure while reducing vibration transfer to – and rattling from – ceiling tile grid system.
  • 1.2 mm (0.05 in) metal thickness provides the additional support required by the long span.
  • Multiple C-ring mounting holes. Additional hole locations drillable by installer.
  • One MTC-48TRx12 is a pack of 12 tile rails, enough for 6 speakers (2 per speaker).
