Blum TANDEM plus BLUMOTION Undermount Slide for Silent, Full-Access Kitchen and Bath Drawers

The Blum 563 TANDEM plus BLUMOTION is an 18 inch full-extension undermount drawer slide with integrated BLUMOTION soft-close, built for concealed installation beneath drawer boxes with 1/2 to 5/8 inch sides. It mounts in both face-frame and frameless cabinets and carries up to 90 lb per pair.

Key Features

• Full extension brings the entire drawer out to the cabinet face so nothing at the back stays out of reach.
• Integrated BLUMOTION soft-close catches the drawer near the end of travel and settles it shut silently, without a separate add-on damper.
• 90 lb weight capacity per pair handles loaded kitchen, bath, and utility drawers with confidence.
• Fits face-frame and frameless cabinets, making it a single-SKU solution across different cabinet constructions.
• Roller-bearing carriage on a steel body with zinc finish delivers a smooth, quiet pull that holds up through years of daily use.
• 3/16 inch side clearance per slide keeps the drawer box width formula tight and the box close to the cabinet interior.

Where This Slide Does Its Best Work

The 18 inch length is the most common drawer depth in residential kitchen base cabinets, making this slide the natural choice for spice drawers, utensil drawers, and mid-depth pot-and-pan drawers built on a standard 21 inch cabinet. Because the slide reaches full extension, every inch of the drawer box is accessible — no reaching past a partly blocked opening to find what is stored at the back. The integrated BLUMOTION damper also means the kitchen stays quieter during early mornings or late-night cooking sessions when a slamming drawer is a real problem. Bath vanities with dovetailed or doweled boxes at this depth are an equally strong fit.

Construction and Finish

Steel members with a zinc finish protect the slide through years of indoor service. The roller-bearing carriage runs quietly under load and does not require lubrication on a regular maintenance schedule. Because the slide rides entirely beneath the drawer box, the zinc finish is functional rather than visible — the clean wood underside of the drawer box is all that shows when the drawer is open. The 563 series pairs with TANDEM plus BLUMOTION front locking devices and rear brackets, both of which are series-specific and sold separately; do not substitute components from the MOVENTO or 552H series.

Who Should Order This Slide

Cabinet shops building production runs of residential kitchen or bath cabinetry will find the 18 inch TANDEM plus BLUMOTION the right balance of premium motion feel and straightforward installation. Designers specifying concealed hardware for remodel projects can call this slide with confidence on face-frame renovation work or new frameless construction. For homeowners replacing a worn or noisy slide, this is the upgrade that adds damped closing to a drawer that used to slam. If the project calls for 3/4 inch drawer sides, look to the 563F series instead; for boxes requiring over 90 lb capacity, the MOVENTO line covers the heavier load class.
