I absolutely love these door knobs. I live in a home that was built in the early 50s on ranch property. I replace the Hollow Corte doors that the previous owner put in with five panel wood doors. I was searching for hardware that had a door plan on it to resemble what ranch doors used to look like. These are the best quality I have ever seen. They are such heavy metal and they’re so solid in your hand it feels like they could be from the 1900s. The mechanisms and how they lock and move is seamless. I cannot say enough about how fabulous these door knobs are in my house. Now I just have to find a front door Knob to go with them.￼￼￼
