Hello, I recently purchased 4 of the Mirror Wardrobe Door Roller items (your product number is
23-070) because your website said they were compatible with the COX item 21-717, 21-767. The problem is that the wheel is concave in the center and the wheels I need to replace are convex, the actually protrude in the center so that they slide inside a track. I'm happy to send a picture if that's helpful. Do you carry anything like that? I'll need to return these...
