A. Provide electrical wiring path
B. Support lighting fixtures only
C. Connect main runners and form grid cells
D. Increase ceiling height
C
Cross tees connect main runners and form the modular grid
framework for tiles.
8. Which condition must be verified before installing ceiling tiles?
A. Roof color consistency
B. HVAC system brand
C. Moisture content of substrate
D. Paint curing time
C
Moisture levels must be checked to prevent sagging or tile damage
after installation.
