M-D Building Products 67967 Vinyl Concealed Kerf/Channel Fit Under Door Seal, Easy-to-Install Draft Stopper, Energy-Saving Door Insulation, Noise Reduction, Ideal for Home (36 Inch, Brown)

I had purchased one of these in a smaller size for the door to my garage, and it was so easy to install and worked so well that I bought another for my front door. You just open the door, pry (carefully) off the old one, and pop this one up into place. The original one I removed was stapled in, but there is no need to staple this in because of the design... it holds itself in place. No more air coming in under the door!

The pictures and spec’s seemed to be good for my off brand door. It ended up being a perfect fit and easy to install.

Good quality, but you need to inspect and measure your door before purchasing: this is designed to insert underneath the door and stay put: first inspect the bottom of your door to ensure that it is hollow, so that they top part can insert inside it. Then measure to ensure that the hollowed-out underside is the right width (7/8"). If your door is wider than that, this will just fall out. I recommend using an adhesive (epoxy glue is my favorite, but a hot glue gun should do the trick), but it's designed to just pop into the underside of your door. Depending on how high your doorframe is set, it make drag too low. If so, the rubber sweeps are easy enough to trim down slightly. Otherwise, it will fall apart from dragging across the floor under too much pressure.

Amazon is offering this product a few bucks cheaper than the orange big box store down the street (and ships Free with Prime)! I had to trim down the length of this door sweep to fit the width of our rear metal storm door and our front wood door. You can do this with heavy duty/utility scissors or box cutter type of blade. I did not have to remove the door. Installation took about 3 minutes. Unfortunately, I can only count on these to last about 2-3 years before the fins start to come off, but they are not expensive and definitely do the job.

Fit my Masonite steel front entry door perfectly, just needed to trim it to the correct width. The "barbs" on the kerf fins give the sweep good holding power so there's no need to staple or glue it to the door bottom. When installing, make sure your sweep is not excessively rubbing the threshold or you will quickly wear out the sweep and probably rip the the flexible fins off the bottom of it. Many metal thresholds have a narrow piece of wood that fits in a slot the width of the threshold which has adjusting screws to tweak the height of the strip. A similar product to this is sold by a company recommended by Masonite for $5 more with shipping costs 70% of the item's purchase price!

Sturdy plastic. Correct size to fit the grooves in the existing hardware but the height was off for my circumstances, no fault of the manufacturer. I had to trim the upper inserts which are thankfully segmented for such. The overall height was too great for my door so I cut off one blade to all the door to close and may have to trim off another if it doesn't become a bit easier to open and close. I suppose this is better than having a gap. Considering the cost it probably would have been easier in the long run just to buy a whole fixture. Live and learn. But for the low price and with some effort, it fits.

Perfect fit to replace a builder install, prehung exterior steel door seal. Originally I snapped it into place and called it good, apparently that wasn't good enough, the seal came loose after about a week from opening/closing the door. I ended up taking the door off the hinges, laying it on its side and tapping it in with a rubber mallet. The plastic fins seem to hold surprisingly well, the last seal lasted almost 13 years so I can only hope this one lasts just as well. A little cheap maintenance goes a long way!

Product fit perfectly in the bottom of my builders door. The bottom of the door needs to have those 2 slots for the fins to fit into. I had to cut the product down and that was a breeze with a hacksaw and then using the razor to shorten the fin on the end! I wish the paper wasn't rubber banded around the product because it made the fins bend a bit, but since they are plastic/rubber then bent right back for easy sweep coverage!

Perfect fit, looks to be a quality door sweep. Removing the door is the biggest issue, as the door was quite heavy, other then that very simple to install, and it seals well.

Sealed my door up tight but left enough room for proper closure. Fits like a glove 👍👍

These sweeps are difficult to find. My door had very little tolerance between the door and the frame. Replacement sweeps that slide on the outside were too thick. This was easy to install but the door needs to be pulled off to complete the job.

Works great on exterior steel clad doors. Make sure your doors require a kerf style trim.

My previous door sweep wore out after 15 years of use ... the rubber parts on the bottom were breaking off. Could not find the right replacement in big box stores. This one via Amazon is the perfect thickness to the thickness of my door. I trimmed off the length from 36" to 32" which was easy. I took my door completely off the hinges and laid it door and it was then easy to install this sweep. No nails or staples. It press fits into the grooves on the bottom of the door. Stars removed because it does not make as tight a fit down my door sill as the previous one. The pieces of rubber from the sweep came all bent over and I tried to straighten them ... they sort of make a decent air block fit to my sill but it could be better.
