Why I Focus on a Lock-On Bathroom Door

Compatibility with My Door
Before buying, I always measure my door thickness and check the backset and latch size. Not every lock fits every door, so I make sure the product is compatible with my setup. This helps me avoid returns and installation problems.
Safety and Child-Friendly Features
