    • High quality replacement at a reasonable price.
Color: White
Tough time finding a suitable replacement for an older metal door. This replacement sweep is a perfect fit and is much better in quality for the same price that the big box stores have in stock. It was very easy to cut to length (I needed 32" for each of the double front doors). Installation was a breeze and it takes paint very well. ... show more

    • Poor quality product!
Color: White
Review Image by Hoadster
This product gets a zero! Poor quality control, and manufacturing of the product. The sealing strips were coming off, right out of the package. Even one of the mounting holes was not drilled. I was going to install but the rest of the sealing strips started to separate from L- bracket. Do not buy!

    • Easy to install and very reasonable price
Color: White
I replaced an old L-shaped door sweep and this fit perfectly and matched my white door. It was easy to cut to size and install. First door sweep was damaged in transit but was replaced very quickly when I submitted a damage claim. I just recently replaced it, so only time will tell how good of quality the sweep really is. We have hot summers and cold winters in Colorado. I hope it lasts many years. ... show more

Slips on under door. Comes with 5 screws. No more scorpions crawling in under the door. :)

    • Under door weather seal
Color: Brown
This was a very good buy. I was very specific in the measurements, so it fit under the door and sealed perfectly. Good purchase.

    • Meh, it'll do
Color: White
I took a chance on this because the reviews were rough. Basically, this got the job done but it's not great. It did arrive in one piece and those little plastic sweep lines on the bottom were not peeling off when I got it. Anyways I went to cut it with my little reciprocating saw which was probably overkill and the 3 strips on the bottom started peeling off. Yikes. I really needed this to work out so I ended up super-gluing them back on! Honestly you can't really tell. So fingers crossed this holds up but it does look nice and new under the door and it keeps bugs out. So just be super gentle with it when you're cutting it to size because it will start falling apart a little bit. ... show more
