Being that I’m a female with next to no handyman skills and needed to seal up my front door, I’m exceptionally pleased with how easy it was to install all by myself. I didn’t even need to trim it to fit. It was a perfect fit on its own. Plus, the only tool I needed to use was a flat-head screw driver to remove/pry the old seal. I did not need to remove the door by its hinges, either. There was just enough room under the door, since the threshold sits up from the floor a bit, that I was able to remove the old and install the new with the door remaining on its hinges. No problem. I can see how in some cases you would have to remove the door, but thankfully that case scenario didn’t apply to me. The seal went right in place from applying a little pressure with only my hands. The only thing extra I want to do now that it’s installed is add a little glue to each of the ends to reinforce the seal there due to its securing tracks/treads that hold it in place stop about two inches inward from the ends leaving the ends a bit sloppy or slack. A little glue between the bottom of door and the ends of the seal should do the trick. I noticed that even the old seal had placed a little glue on the ends, as well. I guess they all have that little slack on the ends needing just a pinch of extra reinforcement. Not a problem at all, I’m sure. Review: Easy to install, attractive for what it is - This review is in regard to the Db370 Notchkrf 36" BGE, as a replacement for one that was nearly 20 years old. Importantly these are made for doors that have a similar piece existing, that can be removed and replaced, which many exit doors have at the bottom. You might not even realize it is removable, as it looks as if it is built into the bottom of the door. In my case it was very easy to remove and reinstall without having to remove the door as the instructions state is necessary, this is not true for all doors. I think they are just trying to warn you of the possibility. The bottom line give it a shot without removing the door, you have nothing to lose. I had enough space to work with from the bottom of the door to the floor. It is often an inch high plus or minus when the door is opened, depending if you have carpet, which is slightly compressible, etc. My application was for a garage in-swing exit, which worked out perfectly. You could consider marking the kerf style insert with a pencil for lining it back up, and than slide it under and push the new one in place, it was extremely easy It snapped firmly into place, and when the door is closed, it seals the bottom of the door to the threshold perfectly, no light, no air. Thinking about doing the rest of the exit doors as it is affordable, looks much better and holds the heat in during winter and the cool air in during summer Thank you ## Features - Effective Draft & Weather Protection: The Vinyl Concealed Kerf/Channel Fit Under Door Seal is designed to provide superior protection against drafts and dust.

Fits perfectly. Glued the ends down with a very tiny amount of construction adhesive since the last one had someone catch it on their shoe or something and pull it out some. Seals perfectly with the existing threshold. This one isn’t the heavier type made of solid metal but as long as they didn’t use worse materials than they used to then it should last as long as the last one. (And I don’t even know how old the old one was. At least 10 years but could have been 20 for all I know.) Basically if this fits it’s probably the one you want. If it doesn’t then you probably got the wrong mounting slot type for the door. It shouldn’t usually need cutting. --- ## 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.hr/products/12264274-md-building-under-door-seal-beige-36in-concealed-kerf-channel](https://www.desertcart.hr/products/12264274-md-building-under-door-seal-beige-36in-concealed-kerf-channel) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-20*
