### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fits well and easy to install
  

*by H***N on Reviewed in the United States on March 25, 2024*

Cut to length with a utility knife, Pulled old vinyl from aluminum threshold and easily inserted new one. Took under 5 minutes👍

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Not the correct replacement, but it works well and the previous identical one lasted 30+ years.
  

*by C***Y on Reviewed in the United States on December 21, 2023*

This was bought in the hope that it was, at least, identical to the old one that's been in this door threshold for over 30 years. The correct version for my door thresholds appear to be discontinued, but these work well, as evidenced by how long the previous one lasted. Now I need to buy 2 more to repair the other two doors that have the same version threshold. These doors aren't used as often and the Threshold inserts in them are well over 45 years, since they were here and in use well before I bought the place.

### ⭐⭐⭐⭐ 4.0 out of 5 stars

*by C***E on Reviewed in the United States on April 15, 2024*
