My kitchen is 20 years old and the drawers of the cabinet are old and not fully extended. These drawer slides are perfect and I use them for cabinet repairs as the old slides fail. They are very well made and have improved the kitchen as they slide out completely and I get 20% more use out of each drawer. The screw hole pattern offers many mounting options and they slide without lubrication. The cutlery drawers are very heavy and slide out both fully loaded and empty.
