4 in. Draft Blocker is rated 4.6 out of 5 by 5.
Rated 5 out of 5 by from Dryer vent drafts solved! During cold weather, I had cold air feeding into the housefrom my dryer vent. The flapper valve on this mount prevents this also cleans up my installation.

Rated 5 out of 5 by from Very useful I purchased this product to install as an in-line block on my dryer vent to prevent backflow of cold outside air into the room where my dryer is located. I use it because typical dryer vents leak air. This device works as a secondary "air block", and does the job very well. A word of caution: If installing on metal pipes (aluminum or steel), you need to be certain that the baffle is not obstructed by the pipe itself. This problem can be avoided by careful installation. The device comes with no instructions, so you must understand your application when purchasing.

Rated 4 out of 5 by from Ok Like most premade stuff have to make it fit for you. It works.

Rated 4 out of 5 by from Worked for my application I used this to replace an outdoor dryer vent that was stuck open. This is not really designed for outside but the thing is I can see if it is open or closed. If your vent is close to the ground like mine you really don't want it sticking open where mice can run it. I think this design will work better for me when it comes to cleaning out the vent which I do regularly using my electric leaf blower by connecting it inside and blowing things out.
