Customer Reviews for M-D Building Products 36 in. Black Vinyl U-Shape Cinch Slide-On Under Door Seal

I liked the idea of a clear bottom door sweeper for the look, but this plastic isn't sturdy. I used this on my front door and liked how this one just slid on without having to remove the door. My old one fit into grooves at bottom of the door and did nothing to protect insects from getting in. I have had it a month and backing is already ripping.

I had an air leak at TOP of door. The clear door seal was perfect. Didn’t have to paint. No more draft of freezing air.

We installed this product (color: white) in August. Today we noticed a white strip under the door. The picture shows how it looks like now. Three strips of plastic are already broken. The one we had before lasted more than 10 years. I would expect a comparable durability, not just 3 months.

Trimmed to door width easily after scoring with sharp knife and slid on. This fixed my old glued on door seal and is almost invisible. It allows light to shine through but no wind blows past it.

It was relatively easy to install.

Just installed but send to be working great

Works exactly like I was hoping! I had to remove the old weather strip that was tacked in to the bottom of the door and then installation was a breeze!

Easy to cut down to size and slide on the door! No more drafts!

Great sturdy product.

It was easy to install and hasn't moved at all. I see no more gaps in the door.

Recently purchased to seal draft from winter cold. Great product. Cut the door seal to size, took off the old one and slid on this one. Made a HUGE impact with no draft coming through. Instantly felt a difference. Easy to install for someone not builder or DIY savvy. Front and garage door complete and will purchase one more for patio. The brown doesn't show dirt or scuffs. Extremely pleased and highly recommend.

It fixed the 1/4" gap under the door and was simple to install.

This product was so easy to install, my previous door seal fell off multiple times, we applied glue to reset the seal. This product was snug enough that no glue was required. It basically took me 10 min to install.

It’s not that good. Slides under the door but, it will hang up on the threshold if it isn’t perfect.

Very easy to install

I installed a new exterior door a few months ago and purchased this so I wouldn’t have to drill holes in it. When i first installed this I was happy. It was a bit hard to slide on because it was so snug but once on it seemed great. 2 weeks later we had a very hot day with the sun shining on the door. I opened the door and the thing had loosened and fell right off. Because it is a vinyl material it warped from the heat. I was so annoyed because when I installed the door I set the gap underneath it so this would fit just right. I didn’t want to deal with returning it and buying a new product that might not fit the gap so I just screwed this onto the door. I wish I would have bought an aluminum one.
