Integrated Soft-Close Undermount Slide for 18 Inch Drawers in Face-Frame and Frameless Cabinets

The Blum TANDEM plus BLUMOTION 18 inch undermount slide is a fully concealed, full-extension runner with integrated BLUMOTION soft-close, built for drawer boxes with 1/2 to 5/8 inch sides in both face-frame and frameless cabinetry. At 90 lb per pair, it handles the demands of loaded kitchen and bath drawers while keeping all hardware hidden beneath the box.

Key Features

• Integrated BLUMOTION soft-close catches the drawer near the end of travel and settles it shut silently, without a separate add-on damper.
• Full extension brings the entire 18 inch drawer out to the cabinet face so nothing at the back of the box is out of reach.
• 90 lb weight capacity per pair covers fully stocked utensil, spice, and bath drawers without strain.
• Face-frame and frameless compatibility makes this slide useful across both traditional American and modern European cabinet construction.
• Roller-bearing carriage on zinc-finished steel delivers a smooth, quiet pull through years of daily use.
• 3/16 inch side clearance sets the box-width formula for the 563H series, keeping the fit precise and consistent.

Where This Slide Earns Its Place

The TANDEM plus BLUMOTION is the go-to undermount for kitchen drawer stacks, bathroom vanity drawers, and furniture pieces where the hardware needs to disappear. Because the slide mounts beneath the box and the BLUMOTION damper is built into the runner itself, there are no exposed mechanisms and no afterthought add-ons to install. Shops building production runs of face-frame kitchens appreciate that one slide version covers both face-frame and frameless boxes — the same SKU works across a mixed project without a separate order for each construction type. In face-frame installs, series-matched TANDEM rear mounting brackets support the back of the slide behind the frame; those brackets are sold separately and are specific to the TANDEM line.

Construction and Finish

Steel members with a zinc finish give the slide its indoor durability without adding unnecessary bulk. The roller-bearing carriage runs quietly under load, which matters most in residential kitchens and master baths where drawer noise is noticed. Because the slide is fully concealed when the drawer is in, the zinc finish is functional rather than decorative — it protects the steel through years of service in a dry, indoor environment. The BLUMOTION mechanism is factory-integrated, so there are no separate damper pods to clip on, align, or lose during a production install.

Who Specifies This Slide

Cabinet shops running medium to high production volume on residential kitchen and bath work reach for the 563H series because the Blum spec is well-documented, the box build is repeatable, and the soft-close behavior is consistent box to box. Designers specifying handle-less fronts or premium pulls get the clean underside look that undermount hardware delivers. Contractors sourcing replacement hardware for an existing Blum TANDEM installation can match this series directly. For 3/4 inch drawer sides, the series is not the right fit — that work calls for a slide engineered to the 19mm thickness. And for drawers needing over 90 lb capacity, Blum's MOVENTO line at 110 lb is the next step up in the same concealed-runner family.
