Comments about American Aldes Aldes 14" Backdraft Damper - BDD14:
This is a well made damper. The only problem I had with the one that I bought was that the pressure sensative adhesive that holds the foam gasket to the perimeter of the damper had already failed on the unit that was sent to me. They should use an adhesive with better longevity. You may have to apply super-glue or some other adhesive and re-apply the foam gasket.
