M-D Building Products 43339 Vinyl CINCH® U-Shape Slide-On Under Door Seal, Easy-to-Install, Energy-Saving, Weatherproof Seal for Doors, Effective Draft Blocker, Ideal for Home (36 Inch, Black)

This replacement door sweep fit perfectly on my 36 inch front door. No cutting or screws required. I had to install it with the door still on the hinges which was a huge pain. I sprayed some grease cutter on the door and inside the sweep to help and had to use a 2x4 block and hammer to get the last few inches on. But once done it works perfect with no complaints. Cannot see the outside light under the door so it's sealed. Looks great too.

This was easy to install. It stays put, and sealed the gap. I was pleasantly surprised. The install probably isn't going to be easy for everyone.In case it helps, here's what I did:- Removed the door and laid it on a large outdoor table.- Cleaned the door and removed any old and worn seal from the bottom of the door.- Held the new weather strip against the door to mark the correct length.- Marked it with an ordinary pencil.- Cut the weather strip with tin snips or metal cutting shears.- Attached the new seal starting at one corner and worked toward the other corner. This was the hardest part because the fit is really tight. I had to use a rubber mallet to persuade the weather strip to fall into place. I also found it helpful to use a thin metal object to help guide the edges of the weather stripping. It was kind of like getting a bike tire onto the rim for anyone who has seen that process.

Easy to install, thick material, creates a tight seal and works really well. The only downside for me was trimming it down a little, but that’s only because I didn’t have a multitool or saw to make it easier- all I had on hand was a pocket knife.Will be reordering to replace on my other doors! Highly recommend.

pretty simple but as the gap gets smaller around the hinge area of one of my doors, this product pinched & the door wouldn't close. Worked fine on the other door....

I thought these were exactly what I wanted - they came and were a bit snug on the door but not too bad. It's been two months and the bottom strips are tearing off from normal opening and closing the door. I can still feel cold coming from my door, but that could also be the door itself. These won't last much longer until they're ribbons.

Used this to stop a draft coming under the door and am very pleased with this. Was a little wide for my interior door but shimmed it for fit and haven’t had a worry about it since. Good product, works well, would buy again!

Did the job! Fairly easy to install, completely stopped the draft.

Genius invention - if you are like me it is time to winterize and the products never seem quite right or like new. This gadget slips right on the bottom of the door and replaces the worn out weather stripping attached to the door. Gives the door a snug closure so no air leaks. We did take the door off the hinges for easier installation because it is a snug fit.
