Blum 563F Tandem Plus Blumotion 15" Soft-Close Full Extension 90 lb Undermount Drawer Slide, Zinc, 26274932

Full-Extension Soft-Close Undermount Slide Built for Thicker Drawer Sides

The Blum 563F TANDEM plus BLUMOTION is a 15 inch concealed undermount drawer slide with integrated soft-close, engineered specifically for drawer boxes with 5/8 inch to 3/4 inch sides. It brings full-extension travel and Blum's BLUMOTION damping to shops building from thicker hardwood or plywood stock.

Key Features

• Designed for 5/8 to 3/4 inch drawer sides — the 563F series is the TANDEM plus BLUMOTION version built around thicker box material, where the standard 563H does not fit.
• Full extension — the entire drawer box travels to the cabinet face, putting every inch of the 15 inch drawer within reach.
• Integrated BLUMOTION soft-close — Blum's damper engages near the end of travel and settles the drawer shut silently, with no separate add-on required.
• 90 lb weight capacity per pair — rated for loaded kitchen, bath, and utility drawers.
• Roller-bearing steel construction with zinc finish — smooth, quiet travel in an indoor-rated, functional finish.
• Suits both face-frame and frameless cabinets — flexible installation across American and European cabinet construction.

Where This Slide Fits the Job

The 563F earns its place anywhere a shop is building drawer boxes from thicker material and wants a fully concealed result. Solid hardwood sides milled to 3/4 inch, dovetailed poplar boxes left at full thickness, or plywood boxes cut from 3/4 inch sheet stock all land in the 5/8 to 3/4 inch range this slide is built for. At 15 inches, the nominal length suits shallower base cabinets, bathroom vanities, and smaller utility drawers where a longer slide would crowd the cabinet interior. Because the slide is concealed beneath the box, the finished drawer presents clean wood faces with no visible hardware.

Construction and Finish

Steel members with a zinc finish handle years of indoor service without issue. The roller-bearing carriage keeps the drawer moving smoothly and quietly under load, and because the slide rides beneath the box it stays out of sight once the drawer is installed. The 3/16 inch side clearance is the published spec for the series; build the drawer box width accordingly. BLUMOTION is integrated into the slide body, so there is nothing additional to mount or align for the soft-close function.

Who Should Order This Slide

Cabinet shops building boxes from thick hardwood or full-thickness plywood are the primary audience. The 563F addresses the gap between the standard 563H — which tops out at 5/8 inch material — and heavier-duty lines, making it the right call when the box design is fixed at 3/4 inch and a concealed, soft-close result is required. It also suits renovation work replacing older slides under drawers that were originally built with thicker sides. Both face-frame and frameless cabinet construction are supported, so the same slide works across a mixed production run or a remodel that combines both cabinet types.

The Right Slide for Thicker Boxes, Built Right

Match the 563F to drawers built from 5/8 to 3/4 inch material, build the box to Blum's specification, add the rear brackets your cabinet construction requires, and each drawer closes silently on full-extension concealed slides rated for the work.
