Blum TANDEM plus OTION Concealed Undermount Drawer Runner Kit 21-Inch Full Extension Soft-Close Steel 100 lb. Load Capacity for Wood Drawers

Upgrade your cabinetry with Blum TANDEM plus BLUMOTION concealed undermount runners, also called drawer slides or glides, designed for a clean look and smooth performance. These 21-inch runners provide full-extension access so you can reach every item and maximize storage space. Perfect for kitchens, bathrooms and custom furniture projects. Before purchasing, check your measurements to ensure a perfect fit. TANDEM runners follow the standard American cabinet depth system. A 21-inch runner pairs with a 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 runners are built for wood drawers and support up to 100 pounds, making them ideal for deep or wide drawers that hold heavy items. Enjoy the luxury of soft close every time. Integrated BLUMOTION technology ensures drawers close gently and quietly, protecting your cabinetry and eliminating slamming. Optional bottom mount holes provide flexibility for attaching runners to the cabinet bottom. Installation is simple, and tool-free height and tilt adjustments let you fine-tune drawer alignment for professional results. Each kit includes everything you need for face frame or frameless cabinets: left and right runners, locking devices, rear mounting brackets and screws. Crafted from zinc-coated steel with a concealed roller carriage and lubricated rollers, TANDEM runners deliver durability and smooth operation for years to come. Proudly manufactured in our North Carolina facility using high-quality domestic and European components, Blum combines innovation with craftsmanship you can trust.
