Salice Progressa 21" Soft-Close Full Extension 100 lb Undermount Drawer Slide, Zinc, G5U6S533XXF6

Undermount Drawer Slide For Face-Frame and Frameless Cabinetry

The Salice Progressa 21 inch soft-close undermount slide is a concealed, full-extension runner that fits both face-frame and frameless cabinets — a practical advantage for shops running mixed construction or installers sourcing one slide for two cabinet types. It handles drawer boxes with 1/2 to 5/8 inch sides and is rated 100 lb per pair.

Key Features

• Full extension brings the entire 21 inch drawer out to the cabinet face, so nothing stays buried at the back.
• Integrated soft-close catches the drawer near the end of travel and settles it shut without slamming.
• Dual cabinet compatibility — the Progressa works in both face-frame and frameless construction without swapping to a different model.
• 100 lb weight capacity per pair handles loaded kitchen drawers, utility pulls, and pots-and-pans storage comfortably.
• Steel construction with zinc finish provides long-term indoor durability on a fully concealed slide.
• Fits 1/2 to 5/8 inch drawer sides — compatible with standard dovetailed and doweled drawer boxes in both thicknesses.

Where This Slide Earns Its Place

The 21 inch length suits base cabinet drawers in the standard 21 to 24 inch depth range — a common spec in kitchen base cabinets, bath vanities, and work tables. At full extension, the back of the box clears the cabinet face completely, which matters in pots-and-pans drawers where reaching past stacked cookware to the rear is part of every use. The 100 lb per pair rating covers the real-world weight of that kind of load without needing to step up to a heavy-duty model. For shops doing mixed production runs of face-frame and frameless cabinets, the Progressa's dual compatibility reduces the number of slide SKUs to stock and track.

Construction and Finish

The Progressa is built from steel with a zinc finish — functional and corrosion-resistant for indoor service. Because the slide mounts beneath the drawer box, the finish is hidden from view in normal use, and the clean look the undermount design delivers depends entirely on the drawer box and front, not the slide hardware. The integrated soft-close mechanism is built into the slide body, so there are no add-on dampers to source or align separately.

Who Should Order This Slide

Cabinet shops building face-frame kitchens, frameless European-style cabinetry, or a mix of both will find the Progressa a straightforward choice at the 21 inch length. It is also a strong match for installers specifying a single soft-close undermount across multiple cabinet types on one job. The 1/2 to 5/8 inch side-thickness range covers the two most common drawer box materials in production shops — 1/2 inch Baltic birch and 5/8 inch dovetailed hardwood or plywood. If your box sides are 3/4 inch material, this is not the right model; look for a slide specified for 19mm stock instead.
