Thick-Side Fit and Full Extension in a Compact 9 Inch Undermount Slide

The Blum 563F TANDEM plus BLUMOTION is a 9 inch full-extension concealed undermount slide engineered for drawer boxes with 5/8 to 3/4 inch sides. It brings BLUMOTION soft-close and roller-bearing travel to the smaller, thick-sided drawers that the standard 563H series is not designed to fit.

Key Features

• Thick-sided drawer compatibility — built for boxes with 5/8 to 3/4 inch sides, covering hardwood and plywood construction in this thickness range.
• Full extension — the entire 9 inch drawer box travels out to the cabinet face, putting every inch of the interior within reach.
• Integrated BLUMOTION soft-close — a damper catches the drawer near the end of travel and settles it shut without a sound.
• 90 lb weight capacity per pair — rated for loaded spice, utensil, and inner-drawer applications despite the compact slide length.
• Face-frame and frameless compatibility — suits both cabinet constructions with the appropriate series hardware.
• Steel construction, zinc finish, roller-bearing carriage — a concealed, functional slide that stays smooth under everyday load.

Where the 9 Inch Length Earns Its Place

Short drawers are common in cabinetry but often overlooked in hardware planning. A 9 inch undermount slide is the right tool for spice drawer inserts, inner-drawer boxes nested inside larger drawers, narrow vanity drawers, and small utility compartments in base or island cabinets. The 563F series is specifically sized for these applications, and because it is full extension, the short box still comes all the way to the cabinet face — nothing hides at the back. The 90 lb per pair rating means a small drawer stacked with canned goods or dense utensils stays well within spec.

The 563F Series and Its Thick-Side Advantage

Where the 563H series is designed around 1/2 to 5/8 inch drawer sides, the 563F is the version Blum built for 5/8 to 3/4 inch material. Shops running hardwood dovetail boxes in 3/4 inch stock, or using thicker Baltic birch sides, need the 563F to get the correct slide spacing, locking-device geometry, and box-width formula. The two series are not interchangeable — the side clearance, the locking devices, and the installation spec differ. Steel members with a zinc finish keep the hardware functional and corrosion-resistant through years of indoor use, and the roller-bearing carriage delivers a smooth, quiet pull at any load up to the rated capacity.

Who Should Specify This Slide

Cabinet shops running thick-sided boxes through a CNC or router table will find the 563F slots into the same TANDEM plus BLUMOTION ecosystem they use for standard-depth drawers. Residential designers specifying handle-less or soft-close interiors for spice towers, inner drawers, or compact vanities get the same BLUMOTION motion quality in the short length. The face-frame and frameless compatibility means a single series covers the shop's output without switching brands by cabinet style. In face-frame cabinets, the slide's back end needs support from the matching TANDEM rear mounting brackets — a series-specific part sold separately. In frameless cabinets, the slide mounts directly to the cabinet side.

The Right Concealed Slide for Compact, Thick-Sided Drawers

The 563F TANDEM plus BLUMOTION in 9 inches solves the specific fit problem of short, thick-sided boxes — delivering BLUMOTION soft-close and full extension where those details would otherwise be skipped in favor of a simpler slide.
