I don’t think it would. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cut to size and you're good to go. *by A***Y on 4 July 2024* Perfect under door seal. Just make sure to measure and cut before installation or it will be a pain. ### ⭐⭐⭐⭐⭐ Review *by M***K on 31 August 2025* Item as described and keeps draft out ### ⭐⭐⭐⭐⭐ Review *by L***A on 13 January 2020* So easy - slides on to bottom of door (Use a hammer to tap it along, into place). It was a little too long - Instructions recommend trimming with saw, but I managed to use a kitchen knife to make a groove, and then I twisted off the extra plastic with a wrench. Just be innovative! Now door closes perfectly and no gap under the door. Once I took off my old door stop piece to replace with this new one, I saw why there was a gap - the old one had all the vinyl flaps worn off. Seems we need to replace every 3 years or so. Worth it for 20$ and so easy! This one has lots of vinyl flaps to keep the cold out. ## Frequently Bought Together - M-D Building Products 43336 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, White) - Holikme Door Draft Stopper Under Door Draft Blocker Insulator Doors Sweep Weather Stripping Noise Stopper Strong Adhesive, White - GroTheory 2 Pack Door Draft Stopper, Under Door Sweep for Exterior & Interior Doors, Weather Stripping Door Seal, Garage Window Blocker Noise Cold Air Insulation, Draft Guard White 2" W x 39" L --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/277036746-m-d-building-products-43336-vinyl-cinch-u-shape-slide](https://www.desertcart.us/products/277036746-m-d-building-products-43336-vinyl-cinch-u-shape-slide) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-12*
