Extron SMK C TB-1 (part number 70-1265-01) — tile bridge ceiling mount kit that carries speaker weight on the ceiling grid instead of the tile.

Suspended T-bar ceilings were never built to hold hardware. Drop a ceiling speaker straight into a cut acoustical tile and that tile absorbs the entire load, which is how integrators end up revisiting a finished job to replace sagging or split panels. The SMK C TB-1 removes that risk by adding a folding C-ring plus a pair of modular V-rails that reach across the cut tile and bear on the grid members to either side. Extron supplies this kit with the SF 3C LP and SF 3CT LP ceiling speakers; ordering 70-1265-01 on its own covers replacement stock, retrofits, and SF 26X installations.

Key Capabilities

• Moves speaker load off the acoustical tile and onto the surrounding T-bar grid.
• A single kit provides support for two speaker positions.
• Folding C-rings and modular V-rails assemble by hand — a tab on one V-rail end locks into the mating slot.
• Matched to the SF 3C LP, SF 3CT LP and SF 26X ceiling speakers.
• Add the SMK VRE 48 V-Rail Extension Kit when the ceiling uses 4 ft (1.2 m) tile grids.
• Compact packaging keeps storage and freight costs down on multi-room rollouts.

Where It Is Used

Classroom and lecture-hall ceiling audio, open-plan office paging, retail and hospitality background music, and corporate meeting rooms — essentially any project where SoundField ceiling speakers drop into a suspended grid and the finished ceiling still has to look right at the client walkthrough months later.
