5' White Linear Air Diverter for a 2 Slot Vent installs easily over any 4’-long ceiling 4 slot air vent. The 5' White Linear Air Diverter for a 2 Slot Vent 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 slot air diffuser 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. Length=59.75" x 3" Deep
