We bought these for our very standard kitchen cabinets, and they do not work. You can not get them tight enough to stay put with a child pulling on them. They slip right off with very little effort. My son just turned 18 months, and he learned how to slip these off right after he turned 1. Having knobs instead of handle is a nightmare!
