Review: Fit like a glove 1"x 36" - This is 1" by 36". I don't understand the negative reviews. Either it fits and you measured/ordered the right part or you didn't measure correctly. That's on you not what you ordered. This was a perfect replacement. I oiled it up to squeeze it in the track. Fit great except It was a little high at first. So I keep addding more 3 in 1 oil to saturate the bottom of the door and now it's a nce tight fit - no problems with the door swing. The original lasted 60+ years. Hope this one lasts. Bought a 2nd simply because it's a hard to find item.
Review: Fit the older threshold - This just fits, plain and simple. Having replaced many of these over my lifespan, I popped down to the local Ace and picked up the one I seemingly buy about every 10 years. It was the only one they had, just like 10 years prior, and thus I assumed it was the one I needed. It was immediately apparent that it was larger than the one I was replacing. So, I hopped on the Googles and found this one. Double checked my measurements and sure enough this is the one that I needed. I have no idea why nobody carries this one, but I can't even find it on MD's website which suggests they've discontinued it. Anyway, this one fit and it arrived quickly. It works fine and in about 10 years I will go back through this whole ordeal again, likely replacing the entire threshold since I'm wagering I won't be able to buy this one again.

### ⭐⭐⭐⭐⭐ didn't fit perfect but works.
*by J***N on April 11, 2024*

This seal didn't fit perfect but well enough. it was just a bit too narrow but seals well. I would buy more but the price went way up right after I ordered this one. I don't know why.
