THERMWELL Frost King AC43H Air Conditioner Weatherseal Tape, 2-1/4 by 2-1/4 by 42-Inch

Arrived as stated and does the job I bought it for. I use these for around my window a/c unit but I also live in a VERY old apt that has many cracks! These can be cut easily for use in sealing cracks around old windows in conjunction with the plastic I also use and these work wonderfully. Easy to install and I suggest the grey.Good quality! Good packaging! Great seller! Recommend!!

It's foam. I use it to close the gap on the top of the open windows when I put the a/c in. Works good for a few times. Then I gotta buy more. Does the job. I buy the 4 inch so I can squeeze it in there and get a good seal.

Used as stuffing to keep bats out of barn roof. Works well and easy to use. Good thickness and length.

So I bought an air conditioner and it's fine in my window but unfortunately the bottom half of the window is left wide open. In come this foam to the rescue. It's covered up that open portion and while it's not a perfect seal it still retain the coolness in my room. Besides the occasional bug that manages to slip by it the foam is decent.

This product works just fine, just the way I wanted it to.

This foam does a great job of filling in the gap of double hung windows when you have them open for a window air conditioner. Good thick size. There is no adhesive on this foam strip.

Great insulation and easy to install

Easy to use, compresses well during install. Does its job, but lasts only a season or two. Dries out and crumbles.
