Installation
Assemble the Tile Bridge
1. Attach the four rails to the center frame using four of the included screws. Insert the screws from the inside of the tile
bridge. The rails and center frame are labeled A and B to identify the correct attachment points.
2. Adjust the length of the tile bridge rails so the rails rest securely on the ceiling grid or furring.
Note: The tile bridge supports 56 to 66 centimeters (22 to 26 inches) spacing.
3. Tighten the four screws securing the tile bridge rails to the center frame.
4. Optional: Attach the L-brackets to the tile bridge to create an additional connection point for a safety wire, safety
cable, or threaded rod. For more information, see Using a Safety Cable on page 5.
Note: Place the L-brackets in a position that does not prevent the anchors on the loudspeaker from fully engaging on
the tile bridge.

Preparing Acoustic Ceiling Tile
Cutting the Ceiling Tile

a loudspeaker hole onto the tile. To center the
template on the tile, draw an X by connecting
the corners diagonally and center the template
using the crossing point.
2. Cut a hole into the tile.
Installing the Tile Bridge
1. Place the assembled tile bridge across the
ceiling grid. If necessary, adjust the tile bridge
so the rails rest on the ceiling grid.
2. Replace the tile in the ceiling.
