    Model HB-120 is a heavy duty industrial backdraft damper with a double-flanged channel frame and single thickness blades.
    Greenheck industrial backdraft dampers are used on blower
    outlets for automatic isolation which allows air
    to pass in one direction and restrict flow in the
    opposite direction. Each damper is factory-adjusted
    for its intended flow direction. Multiple nested
    counterbalance arms and weights are positioned
    to reduce load on bearings and linkage. Industrial
    backdraft dampers are recommended for low
    temperatures and clean air applications.
    The flanges have a small remnant
    of duct sealer and small holes from self-tapping screws as seen in the pictures.
    Buyer will receive the item as pictured.
