Zinc Ball-Bearing Undermount Slide Built for Both Cabinet Styles

The Pro Value Series PRO 560 is a 21 inch, full-extension, soft-close undermount drawer slide designed for cabinet shops and installers who need concealed hardware that works equally well in face-frame and frameless cabinets. It runs on ball bearings, carries 100 lb per pair, and closes silently on an integrated soft-close damper.

Key Features

• Full extension brings the entire 21 inch drawer out to the cabinet face so the full depth of the box is reachable.
• Integrated soft-close catches the drawer near the end of travel and settles it shut without slamming.
• 100 lb weight capacity per pair handles loaded kitchen, bath, and utility drawers.
• Ball-bearing carriage on a zinc-aluminum body delivers smooth, consistent travel under load.
• Dual cabinet compatibility suits both face-frame and frameless construction, so one SKU works across mixed shop runs.
• Maximum drawer side thickness of 5/8 inch covers the most common dovetailed and doweled box stock.

Where This Slide Fits the Work

At 21 inches, this is the go-to length for standard base-cabinet drawers in 24 inch deep cabinets. The full-extension travel means a homeowner can reach the back of a spice or utensil drawer without digging, and the 100 lb rating comfortably covers a loaded pots-and-pans pull-out or a heavy file drawer. The soft-close damper keeps things quiet in residential kitchens and eliminates the wear on box joints that repeated slamming causes over time. Because the slide suits both face-frame and frameless cases, shops running a mix of traditional American and European-style cabinets can stock a single slide length rather than managing two separate SKUs for the same job.

Construction and Finish

The PRO 560 is built from zinc-aluminum with a zinc finish. Ball bearings running in formed raceways give the slide a controlled, even feel across the full 21 inch stroke, and the zinc finish holds up through the regular cycles of a residential or light-commercial install. Because the slide mounts beneath the drawer box and out of sight, the finish is functional rather than decorative — it protects the metal through years of indoor use.

Who Should Order This

This slide is sized for cabinet shops producing standard-depth base cabinets in volume, renovation contractors sourcing for kitchen or bath installs, and serious DIYers replacing worn hardware on existing cabinetry. It delivers the full-extension soft-close combination that has become the baseline expectation in residential cabinetry, at a value price point that makes sense for runs where premium-brand pricing is hard to pass through. The 5/8 inch maximum drawer side thickness matches standard shop-built dovetail and dowel boxes; if your boxes are 3/4 inch stock, look to the appropriate side-thickness model instead.
