    Does the Job.
  

*by C***S on Reviewed in the United States on March 30, 2022*

We had a new range hood installed with a new outdoor vent.  Last winter we noticed a strong draft in the winter around the range and realized the HVAC contractor never put a damper in the vent.  I purchased this was able to install it - I had to do some minor adjustments but I got it into the vent.  I tested it and the vent readily opened on the lowest fan setting and was stable at the highest fan setting.This year there is no draft around the range and it shows up in our heating bill.  Very satisfied, it does the job at a reasonable cost.

    Required some modifications
  

*by M***S on Reviewed in the United States on December 31, 2013*

I purchased the 6 inch model which apparently is no longer available, and was much less expensive (about $35).  It does not look like the ones that are pictured.  It has one outside rubber seal, and two small springs wrapped around a central shaft.  This damper can be installed so that the exhaust flows upward or horizontally, but not down.  If the exhaust is flowing down, the two springs are too weak to close the metal flaps.  Due to the location of my bathroom fan, I had no other option but to install the damper facing down.  But the flaps would not seal completely.  If the manufacturer provided a spare spring, the problem could be solved.  I ended up having to remove one spring and rotating it one more revolution around the shaft to fix the problem.  It was extremely difficult to do, and I don't recommend you do this unless you have lots of patience and plenty of time!This damper comes with a sponge rubber (similar to weather stripping) wrapped around the outside.  It has an adhesive backing.  I had to use a hair drier to remove the rubber so that it would fit inside the duct.  I then clamped the damper to the duct using a metal screw-type clamp.Except for these modifications, the damper worked fine.Note, I would not recommend this product at its current $70 price.
