Review: Was very strong and easy to lock and unlock . - Worked great and seemed very secure. I would order them again if I need this kind of lock. The order came quickly also.
Review: Very Good Quality Product - The bolts themselves were good quality, it just took a lot of effort to get them to fit in the spot needed (door's fault, not the product). I measured what I needed and this was the closest to the fit that I could find. If anyone is planning on replacing your flush bolts, get the closest size to fit you can find and plan on a lot of grinding to make it fit. In the end, they work well and look good. Even with the extra work, it was still better than spending hundreds of $$$ on replacing the Astragal.

### ⭐⭐⭐⭐ Good replacement part
*by T***R on August 12, 2022*

Seems sturdy and was not hard to install. Serves its purpose well. My only complaint is that the lever is hard to pull. I have to pry it up with a tool to open or close.
