Under Door Draft Stopper for Bottom of Doors 38" Black Door Blocker Noise ReducerLight Cold Air Guard Breeze Sound Proof Door Sweep Weather Stripping Door Seal Insulation Strip Gap Filler

Works perfectly!!!

If it does not fit, make it! I have a door that needed this and the floor on the exterior is not flat. I put this together (used the double sided stickers and tape) cut it to fit the door. I kept the inside foam roll whole, cut the outside foam roll with a razor blade, taped the joints together again (to reinforce them since I cut the tape off while customizing), and it works great!! This is not intended to keep sound/noise out. It is a draft stopper; keeps the cold out and warm in or warm out and cold in…depending on where you live and if you have seasons. It is 11° here and my house and nice and warm thanks to this!! I threw 3/4 of one side in the trash as I only need 1/4 of it to fit my door and it still works! It is foam, people!!! You can easily slice it with a razor blade! There is a nice Velcro feature to secure the extra slack if you have a smaller door. This also works great to keep bugs OUT!!! It happens to be my second time purchasing one of these. Last time I bought one was in 2016. This updated version is much sturdier, and the quality has improved tremendously!!

I purchased this door draft stopper for a bedroom door that lets in a lot of hallway light (and sound). Overall, it does a good job at blocking light and muffling noise when the door is fully closed, and it’s easy to install. You simply cut it to length, slip the foam into the fabric slots, and slide it under the door — installation took just a few minutes. The biggest issue for me is that my door is set slightly higher off the hardwood floor. Because of that, when I open or close the door, the stopper tends to slide under the gap and create some resistance. It’s not unusable, but it is inconvenient. I imagine on a door closer to the floor, this wouldn’t be a problem. As for quality, it’s foam — so it’s not meant to be heavy-duty, but it’s sturdier than I expected. The foam doesn’t tear or crumble easily, and it holds its shape well. This isn’t a security device, but in theory, if someone tried to open the door from the outside, it would add a little resistance since it wedges under the door. For the price, I think it’s a fair buy, especially for doors with less clearance at the bottom. It works well in most situations, and my issue is probably unique to the way my door is built. TL;DR: Easy to install, blocks light and sound effectively, but if your door sits too high above the floor, it may slide under when opening/closing.

stops drafts and slides over floor with no problems

I ordered this to prepare for my home office set up in March for April. I just opened it tonight and I cannot believe how much of an actual joke this was. Not only is it not black like the description on the box says but it’s literally just two pieces of gray foam! There’s no way to even secure it to the freaking door. It’s basically just two miniature pool noodles and of course since it’s outside of the return window, I can’t even return the POS. Thanks for scamming me. Real great!

Room is airtight now after modifications. The sticky’s didn’t work

I think it will help keep our apartment cool—it’s really hot in the hallway.

Love this product helped so much with both keeping cold out and helps with noise I used them in two different doors and it helped on both rooms love it will buy more

Very low quality, you have to glue together the 3 small sized foams and insert them inside a low-quality fabric to make the two sides of the product. Very poor quality overall. Do not recommend at all!

This was bought as a "stocking stuffer" for a close friend. I recently built a room in her garage that has a 3 degree slant. when open, the end of the door scrapes the floor a little, and when closed has a 1" gap. Unfortunately, we also have a rodent issue in this region, and having that gap was unnerving. This product is perfect for this situation . It insulates, reduces noise, prevents rodents AND works on uneven / un-level flooring. good price and prompt shipping as well.

Rubbish

Bad product zero rating

It stopped the strong draft that would sweep cold air into our unit. It also stopped the whistle sound that. Was produced with other draft products we tried. My only concern is how durable the fabric will be and since it is a smooth silky material I had to use back to back tape to keep it in place. Time will tell how well it will last.
