    Added Security
  

*by W***T on Reviewed in the United States on January 9, 2023*

We’ve tried to harden our home as best we could. This hopefully helps against kick ins. Looks nice too.

### ⭐⭐⭐⭐ 







  
  
    Measure your door
  

*by H***J on Reviewed in the United States on July 24, 2022*

A tad largeer than the thickness of my bedroom door but my fault for not measuring. Still worked to cover up a broken area from locking myself out.

### ⭐⭐⭐⭐⭐ 







  
  
    Even at 70, this was easy to work with.

     I had been broken into and they took my spare keys (God love 'em). Between this and my new locks, I believe I'm set!
