Why I Care About the Right Lock for Glass Doors
When I started looking for locks for glass doors, I quickly realized that not every lock works the same way. Glass doors need a lock that is secure, easy to use, and gentle on the glass itself. I wanted something that would protect my space without making the door hard to open or damaging the glass.
Types of Locks I Looked At
I found that there are several common types of locks for glass doors, and each one serves a different purpose:
