4' White Linear Air Diverter for a 3 Slot Vent

4' White Linear Air Diverter for a 3 Slot Vent installs easily over any 4’-long ceiling 3 slot air vent. This diffuser features a perimeter flange that enables it to be installed without tools by resting the flange between the vent and the ceiling grid support system. Once installed, the White Linear Air Diverter for 4 Foot Vent redirects the hot or cold air flow leaving the vent so it flows more evenly throughout the space rather than it being forced down in one spot. The result is a much more comfortable office space.
