A drop ceiling diffuser lays into your standard 24″ x 24″ T-bar ceiling grid and distributes conditioned air across the room. The 3-cone design pushes air in four directions for even coverage. R6 insulated back prevents condensation and energy loss. If you’re replacing a damaged tile diffuser in an office, shop, or commercial space, this drops right in.
