    4″ Butterfly damper perfect for “supply air”

    We use these when sealing a crawlspace or attic. As an insulation contractor, we use spray foam to encapsulate & insulate these areas for homeowners. The 4″ damper is inserted into an HVAC supply plenum, so that the HVAC conditions the area, and aids in the control of high RH.

    Butterfly Backdraft Damper

    This is a very good product. It is made to specifics and is exactly as stated.
    We are doing a fairly large industrial project and have purchased several of these this year. We have had no problem with this product.
