Undermount Drawer Slide For Deep Drawers and Heavy Loads

The Blum MOVENTO 21 inch undermount slide brings full-extension, soft-close performance to deeper drawers that need a higher capacity runner. Concealed beneath the drawer box, the MOVENTO carries 110 lb per pair and closes on integrated BLUMOTION damping, making it a natural fit for pots-and-pans drawers, deep pantry pull-outs, and any application where a 21 inch box carries real weight.

Key Features

• Full extension brings the entire 21 inch drawer to the cabinet face for complete access to the back of the box.
• Integrated BLUMOTION soft-close catches the drawer near the end of travel and settles it shut silently without a separate add-on damper.
• 110 lb capacity per pair handles deep, heavily loaded drawers that outpace standard 90 lb undermounts.
• Fits face-frame and frameless cabinets so one slide family covers both construction types in the same shop.
• Steel construction with zinc finish running on roller bearings for smooth, quiet travel through years of indoor use.
• 3/16 inch side clearance keeps the concealed profile tight while leaving the runner fully hidden beneath the box.

Where This Slide Earns Its Keep

The 21 inch MOVENTO is the right call when drawer depth and drawer weight both go up at the same time. A deep kitchen base drawer loaded with cast iron, a 21 inch spice pull-out stacked with glass jars, or a pantry box carrying canned goods all put a 90 lb slide close to its working limit. At 110 lb per pair, the MOVENTO keeps the same concealed, soft-close profile while absorbing that extra margin. It also suits bath vanities and built-ins where 21 inch boxes are the standard depth and the client expects a premium close. For shops building consistent drawer programs across a range of base cabinet depths, the MOVENTO slides in at 21 inches without changing locking devices, brackets, or installation method from shorter lengths in the same series.

Construction and Finish

The MOVENTO runs on a roller-bearing carriage inside steel members, finished in zinc. Because the slide mounts beneath the box and stays hidden when the drawer is open, the zinc finish is purely functional — it protects the steel through daily cycles rather than contributing to the visible hardware finish. The BLUMOTION damping mechanism is built into the slide body, so there are no separate soft-close clips to source or lose. The 3/16 inch side clearance per slide keeps the overall installation compact.

Who Should Order This Slide

Cabinet shops and installers running premium kitchen and bath programs that call for deep undermount drawers will find the 21 inch MOVENTO the most direct specification for their 21 inch box depth. Designers spec-ing drawer hardware for higher-end residential builds where handle-less fronts, wide drawers, and smooth motion are all on the list will find the MOVENTO compatible with Blum's TIP-ON and SERVO-DRIVE motion systems. Homeowners replacing worn slides in a deeper base cabinet — where the existing hardware falls short on capacity or no longer closes softly — can step up to MOVENTO and stay with Blum's ecosystem. This is an indoor slide for wood and panel drawer boxes; it is not rated for wet, exterior, or marine environments.

The Right Slide for the Deeper Pull-Out

When the drawer is 21 inches deep and the load is real, the MOVENTO delivers the capacity, soft-close, and full-extension access the job needs — all from a slide that stays completely out of sight.
