    Works well
  

*by M***E on Reviewed in the United States on July 4, 2018*

The portable ac unit I purchased allowed hot air to flow back into my house when not being used. This damper fixed the issue

    All Plastic, but works OK

I replaced a years-old metal damper with this.  Well-enough made, and fits the old ducting.
