My oak cabinets are 20 years old. The way the doors are made, required a Reverse Bevel Hinge. This hinge fits the angle of the cabinet door. I could not find these in any Hardware store. I was thrilled to find them on line and ordered them from ATG. I also purchased new knobs and pulls. My cabinets now look like new! I would have rated the product excellent in all catagories if it had been American made. There were no instructions, but it was easy enough to figure out how to screw the hinges on.
