6" Round Ceiling Vent Cover with Foam Seal through hole friction mount

6" Round diffuser handle mounted ceiling vent cover.

Our closed cell foam seal eliminates air flow between hot and cold spaces, saving energy and preventing condensation, mold, and water damage when your HVAC is not in use.

Featuring a sealing surface diameter of 7 1/8" to 7 3/4".

Easily installed by homeowners to reduce heat loss by preventing warm air from rising into attic duct work and causing condensation issues. Protect your home with our patent pending solution. Dampers only slow down the air they do not block the hot air escaping into your attic space! Don't wait, completely seal up your vents!

Note: The damper handle is not provided and it's best to use your existing damper handle for mounting. An O-Ring is provided to seal around the damper handle and cover to eliminate all air flow. If you do not have a damper handle consider our rare earth magnetic mounted option or shoot us an email for other mounting options.
