M-D Building Products 13524 1-1/4 in. x 3/4 in. x 36 in. Gray Vinyl Replacement Insert for Adjustable Aluminum Threshold

Works very well. Description is dead on. And you cut to fit.

Used as replacement in 30 year old adjustable threshold. Fitment is secure, but was easy to slide in without having to use soap.

First purchased this item 9/02/25 for $14.94. Today, 9/22/25, I purchased the same item and the price was $8.99. WTF? Item itself is decent quality.

Works to perfection.

This product fit a very old (30+ years) aluminum threshold perfectly. It was an easy install, considering the age and corrosion associated with the old threshold. Would recommend.

Replacement for a threashold I installed 30 some years ago. I wasn’t sure I could find anything that fit, but this one fit fine. Shipped quickly and fit. This is a definite five star.

I looked high and low for this piece in all my local stores and searching online, but never finding exactly what I needed. I don't remember how I stumbled across this one, but I'm so glad I did. A perfect match for what was needed. Installation was a breeze. Measure, cut, slide it in. Done. Front door back to being sealed. 5 stars.

Difficult to install.

Used this product to replace a damaged threshold for my customer Another contractor replaced the original Threshold with 2 36 inch thresholds, they were of different height and the left door did not seal properly. I ordered this thresholds vinyl replacement to replace the old vinyl in the old frame Vinyl was very tight to pull through, sprayed soap in the tracks while pulling. Overall perfect replacement for the old threshold. I would recommend this product.

Our home is 35 years old and the rubber sealing strip in the threshold of the door into our garage had disintegrated a few years ago. I couldn’t find a replacement seal at the usual places like Lowe’s and Home Depot so I added a sweep to the bottom of the door to save having to do the much bigger job of replacing the whole aluminum threshold. The sweep solution wasn’t really a great fit... didn’t look great and wasn’t a great draft free fit. I found this replacement threshold seal on Amazon, it arrived quickly and installed literally in 2 minutes. It fits perfectly and the door is now draft free. I had to remove the sweep I added onto the bottom of the door so that the door would close properly, but thats a bonus as aesthetically it looks much nicer. So far I’m very pleased and would highly recommend.

I searched for years for a replacement threshold insert and finally found this one. It fits perfectly, although it looks totally different from the original insert. It’s actually a much better product than the original. I would highly recommend this item.

Trivial to replace. They wear out after a few years of constant foot traffic, you replace them in a few minutes and everything is as good as new.

Wasn't sure if it would clip intp my existing aluminum threshold, but it did and locked in with a bit of pressure. Very pleased.
