  • Easy Installation: Designed for easy, tool-free installation, this seal slides seamlessly onto the bottom of your door, providing an instant barrier against drafts and noise. Its U-shape design ensures a snug fit on most standard doors up to 1-3/4" thick, eliminating gaps and enhancing the overall efficiency of your homes insulation. Spend less time on setup and more time enjoying a comfortable, draft-free environment.
  • Enhanced Noise Reduction: In addition to its weatherproofing benefits, this door seal effectively blocks unwanted noise, creating a quieter and more peaceful indoor environment. Whether used on entry doors, interior doors, or office doors, it helps to reduce the transmission of sound, making it ideal for homes, apartments, and workplaces where minimizing noise is a priority.
  • Energy Efficiency and Cost Savings: By sealing gaps under your doors, the Door Seal helps to improve your homes energy efficiency. This results in lower heating and cooling costs, as your HVAC system doesn't have to work as hard to maintain a consistent temperature.

    • Product sucked‼️
Color: Black
This product is. HORRIBLE‼️ would not even give it 1 star. Fit it in & when I closed the door, the strip broke apart on the other side.

    • Fits great
Color: White
Works great! Our dogs would destroy other ones and this one fits tight along the door, which makes it difficult to get behind and break.

    • Precise Fit, Excellent Draft Seal-cum-Insect Barrier
Color: White
It was such a breeze to install this door (bottom) seal. It's U-shaped so it slides right under the door very easily. All I had to do was measure the door width and cut the door seal with a hacksaw ("measure twice, cut once"). The 4 fins at the bottom of door seal act as multiple layers/barriers that effectively close the gap at door bottom thereby preventing cold air in an air-conditioned room escaping as well as keeping insects out that would otherwise be creeping in through the gap. Yet another excellent product from M-D Building Products. ... show more
