## Customer Reviews

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Fit the older threshold
*by S***T on January 12, 2024*

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.

### ⭐⭐⭐⭐⭐ Simple replacement - Rubber seal presses in
*by W***E on July 13, 2023*

Easy replacement, great quality. Screw down aluminum to threshold and simply place rubber gasket over the runs that it will secure into and press in by hand, finish by foot
