## Description

M-D Building Cinch® U-Shape Slide-On Under Door Seal, White, 36in - desertcart.com

Review: Easy! - I’m very pleased with this door sweep. I removed the old one, cleaned the bottom of the door, measured everything according to the instructions, and cut the new sweep to length with a hacksaw. It cut very easily. The fit was quite tight, which I consider a good thing. It took a fair amount of pounding with a hammer and a block of wood to slide it completely across the door. After installing it, I used a screwdriver at an angle for leverage to push the sweep snugly against the bottom of the door along its entire length. Once I did that, the door closed properly and the seal was excellent. I positioned the slightly rougher cut end on the hinge side, where it’s hidden. I could have smoothed it with sandpaper, but since nobody will ever see it, I didn’t bother. Overall, this was straightforward to install, feels secure, and provides a nice, tight seal. It works exactly as I hoped. We’ll see how it holds up over time, but my first impression is very positive.
Review: Easy Fix for Drafty Doors - Installed this M-D Building Products door bottom seal on my exterior door to help block drafts, and it made a noticeable difference right away. The cold air coming in under the door was getting annoying, especially at night, and this solved the problem without needing a complicated install. The slide-on design made installation very simple. I only had to trim a little off the length for a perfect fit, and it slid onto the bottom of the door securely without needing a bunch of tools. The flexible vinyl seals nicely against the floor without making the door hard to open or close. I also like that it covers a fairly wide gap range, which helped on my older door that wasn’t perfectly even. It looks clean once installed and blends in well with the black door trim. For the price, this is an easy and effective upgrade if you want to reduce drafts, dust, or even bugs coming in under the door. Definitely worth picking up.
