Product review (5 stars): Best dryer vent closure
This is the second time I have had to install this type of dryer vent. I bought one like this in the early 90's from another company. It lasted longer than any other type I have ever had before. It probably would still be attached to the house, but my brother leaned something against the house, which turned over and broke the old one. Also, they recommend painting it to protect from UV rays from the sun, however if your vent is in the shade, than I don't see how that would help. I did get this product faster and cheaper through Amazon.
