Question: How come there are only screw holes on one side? How does the other side stay in place?
Document: perfect product to seal the bottom of my double door front door. Makes a good fit, and sealed up the opening between the door and the floor. Easy to install. Screws come with the door seals, but if you are lazy you can just use glue and install it. The fit is snug so it holds onto the doors very well. Oh for your information, the side with the screw holes is the interior side. Also after installing the door seals, it was very hard to open and close the door since the initial opening between the door and floor wasn't that big to start with.
If you intend to remove your old door bottom, and SLIDE this one in place, this is not for you. The upper portion had close inward to 1 5/8 inches. It was impossible to SLIDE under the door. Also, the hole spacing is at 8 inches rather than the normal7 inches. This would have required drilling another hole at one end of the strip into my 36 inch door. Best bet is to purchase one where the 2 side rails are parallel at the 1 3/4 inches, at a store and, if possible, with the hole spacing at 7 inches.
The build in sweep on the bottom of my garage entry door had almost a 1/4&#34; gap on one side. The sweep was built into the bottom of the door so replacement would be no easy task. I did have to actually pull the whole door off to remove the existing sweep, but installing this new one was a breeze! It fits tight enough that I did not need to screw it in. I was able to adjust it to make a nice tight seal. The quality seems decent enough, we will see how long it lasts, but I can tell you that it's holding up pretty good after 1 month.
The bottom fins are fairly flexible. Shouldn't be too hard to open and close the door. It was delivered without damage or parts bent the wrong way. Can't be found at home-d or lowes. Good price for the functionality. No instruction. I assume screw holes face indoors. This will catch water and contribute to rot or leaking into the house. I plan to use Everbond tape between the weather strip and the door, and caulk/paint in spring.
Does what it's supposed to. Fins come down too far for my door. My fault though, as the measurement for the item are posted.
This blocks sound and the flow of air, both desired effects for me! This was a bit wider than my door, making it tough to keep in place. I finally used some adhesive putty on the bottom, and it works great!
If your exterior door sweep is worn out, this is an inexpensive and easy to install fix. It just snaps onto the bottom of the door. You can screw it on if needed but I haven't had any issue with it moving without screws. My only complaint is that the factory shrink wrap compresses the fins. I had to heat up and 're-bend' the fins to get them to stand up again.
This sweep is easy to install. You can trim it to length with a box cutter or sturdy scissors and it screws into place quickly. The ridges on the bottom are rather stiff, and don't deal all that well with any surface imperfections. They will also start to peel off after a year or so of steady use. It's cheap and easy enough to buy replacements each year, but I'd rather spend more for a better product.
I bought a house built in the 1950's a couple years ago. The mudroom has always felt very drafty. This year in CT it got so cold that I had ICE forming at the bottom of the interior side of the mudroom's outside door. I looked down there and when they replaced the threshold, the existing air seal didn't touch. Ordered this, cut it to size with a small hacksaw, and it slipped right on. Makes a very tight seal at the bottom of the door. No more draft, and certainly no more ice.
I purchased and installed several other door bottoms which did not work for various reasons, but this one worked for me.
