If the ceiling reinforcement ring does not line
up accurately with the ceiling mounting hole,

tie-plate mounting screws to the appropriate
holes in the Tile Bridge rails.
The ceiling reinforcement ring can be moved
in the direction indicated by the arrows.
Note
Be sure to tighten the tie-plate mounting
screws after completing the adjustment.

then open it with its tabs facing up.
Place the ring on the ceiling panel aligning it
with the mounting hole.
