Optional bottom mount holes provide flexibility for attaching runners to the cabinet bottom. Installation is simple and tool-free height, side and tilt adjustments let you fine-tune drawer alignment for professional results. Before purchasing, check your measurements to ensure a perfect fit. TANDEM slides follow the standard American cabinet depth system: an 21-inch runner pairs with an 21-inch drawer length. For face frame cabinets using rear mounting brackets, your inside cabinet depth should be at least 21-15/16 inches and no more than 23-19/32 inches. For frameless cabinets, only the minimum depth matters. These slides are built for wood drawers and support up to 100 pounds, making them ideal for deep or wide drawers that hold heavy items.
