### ⭐⭐⭐⭐⭐ Are nice quality easy to install and worked well. They come with 3M self adhesive gaskets.
*by T***R on April 21, 2025*

Are nice quality easy to install and worked well. They come with 3M self adhesive matching shaped gaskets, with an extra included. The metal is security worthy thick, but not too thick. We used it on our outside rear gate, with the 2x6 lumber was too thin for a traditional exterior locking door know/handle. Adding this not only matched the handle but increased the thickness and added strength it the installation. It was packaged well and arrived in normal time. Recommended.
