Die-Cast Round Bi-Fold Door Knob, 1-1/4 Inches with 1-3/4" Backplate, Polished Chrome by Stone Harbor Hardware

I wanted a door knob for my bi-fold doors that matched the door knobs in my bedroom and bathroom. They are great. I did have one problem with the screw. It looked like a small piece of metal was in the slot for the screwdriver so I could not tighten the screw. They did provide a longer screw that did work. I really hate the tiny wooden knobs that come with the door. The gold ones look so much better.
