MD Building Under Door Seal, Beige, 36in Concealed Kerf/Channel Fit

I loved the simplicity of installation! 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.

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

Exactly the same as the one from 10+ years ago that was getting a bit worn out. 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.

Perfect fit, easy to install.

My door is a 32 inch door so I had to cut this to fit. I cut the length with a hack saw, and then I measured the distance that the kerfs are back from the edge and cut those kefp portions off too so that it would fit in the slots in the bottom of my door. It was very easy to cut to the correct length and fits perfectly and works perfectly. Buying the wrong size and cutting it to size saved me $20 over other options on Amazon. It seems to be the same type of door seal as I had before which is great. I can't speak to the longevity of this particular seal, but the price alone would let me buy 3 or them for the price of other similar options on Amazon. I would definitely recommend this route!

These work great to replace the door sweep on our rental units with 36" doors. They are easy to install, and like these better than the originals which has either 3 or 4 wiper stripes that aways ripped off. This one has 2 bulb type wipers which should last much longer.

Attached to the bottom of my door like a breeze. I didn't remove my door and had an easy time sliding this in and popping it with my hand until it clicked into place.

This under-door seal was simple to install and fit perfectly into the kerf channel of my door. It immediately reduced drafts, helped keep out dust, and even cut down on outside noise. The vinyl feels durable but flexible enough to create a good seal without making the door hard to open or close. The beige color blends in nicely, and it’s an inexpensive way to improve comfort and energy efficiency at home.

This is a high quality door sweep that doesn’t fail in a short time like the other ones did and it seals perfectly. Was super easy to install.

Couldn't find kerf style sweeps anywhere in local hardware stores. This was ready to install and adjust to fit our door perfectly.

Fits well and works. Nothing to complain. Ideally if the vinyl fins could be a bit more durable.

Exactly as described! Worked perfect on my door. My local home depot doesn't carry this particular seal. Price is right. Thanks!

Highly recommend. Great product and great seal
