21" 563H TANDEM plus BLUMOTION Undermount Drawer Slide for 5/8" Material, Soft-Closing

The Blum 563H Tandem plus BLUMOTION Undermount Drawer Slides are a premium solution for smooth, quiet, and reliable operations. Designed for 5/8” drawer material, Blum’s 21” undermount drawer slides with soft-close functionality support up to 100 pounds and provide full-extension access. For 1/2” drawer material, consider the Blum 563, which offers the same dependable soft-close capabilities and full-extension design for thinner drawer sides.

Each slide features four-dimensional adjustments for precise alignment, including elongated holes that make depth and height tuning easy during installation. Blum’s Tandem drawer slides are highly versatile and compatible with face frame and frameless cabinet constructions. For use in kitchen cabinetry, custom furniture, bathroom vanities, and more, concealed undermount slides function well for both residential and commercial installations.

With the BLUMOTION soft-close mechanism built into the slide, drawers close smoothly and silently every time to deliver the high-performance motion Blum is known for. These concealed runners allow the craftsmanship of pull-out drawer boxes to shine while providing long-lasting durability and motion that meets the expectations of professionals and homeowners.
