It fits perfectly on door knobs from the 70s-80s that were usually embossed and bronze. It's great! I recommend it!

It is a basic knob that does the job and is worth its good price. However, do not expect it to be a regular knob. It has nothing to do with the knobs from well-known companies that we have in our homes. It is a knob that you encounter in a cheap hotel room. You can immediately tell by the thickness of the material. And the average processing of the curves. However, it works normally. And for its money, it is okay.
