Salice Progressa+ Undermount Drawer Slide For Face-Frame Cabinets With 3/4 Inch Drawer Sides

The Salice Progressa+ is an 18 inch full-extension soft-close undermount slide engineered specifically for face-frame cabinets and drawer boxes built from 3/4 inch material. Rated 170 lb per pair, it sits in heavy-duty territory for a concealed undermount, making it a strong choice wherever thick-sided drawer boxes and demanding loads come together in traditional American casework.

Key Features

• 170 lb weight capacity per pair — handles heavily loaded kitchen, pantry, and utility drawers well beyond the 90 to 100 lb standard class.
• Full extension — the entire drawer box travels out to the cabinet face, putting every inch of drawer depth within reach.
• Integrated soft-close — a built-in damper catches the drawer near the end of travel and settles it shut without slamming.
• Face-frame cabinet configuration — this version is built for face-frame construction; rear mounting brackets are required and are series-specific to the Progressa+ line.
• 3/4 inch (19mm) drawer side compatibility — sized for boxes built from 3/4 inch hardwood or plywood, a separate fit class from the 5/8 inch version of this line.
• Steel construction with zinc finish — built for long indoor service, fully concealed beneath the drawer box when installed.

Where It Earns Its Place

Face-frame cabinets present a specific mounting challenge: the slide's rear end needs support behind the frame, and that support has to come from brackets matched to the slide series. The Progressa+ is built around this reality, with a face-frame configuration that pairs with its own rear mounting brackets. For shops running traditional American base cabinets — kitchen base runs, built-in pantries, laundry and utility cabinetry — this slide delivers the clean, hardware-free look of a concealed undermount without compromising on load capacity. At 170 lb per pair, it covers the kind of drawers that would stress a standard undermount: pots-and-pans pullouts, deep pantry drawers, or heavily stocked utility drawers in a mudroom or workshop cabinet.

Build and Finish

Steel construction keeps the slide rigid under load, and the zinc finish provides the corrosion resistance expected from indoor cabinet hardware. Because the Progressa+ mounts beneath the drawer box, the slide body stays out of sight once the drawer is installed — the zinc finish is protective, not decorative. The drawer box must be built to Salice's published specification for the Progressa+ series: nominal 18 inch length, the correct box width, bottom recess, rear notch, and drilling for the Progressa+ front locking devices. The box-width formula and notch requirements are specific to this series; an unmodified box will not seat correctly on the slides.

Who This Slide Is For

Cabinet shops and finish carpenters working in face-frame construction with 3/4 inch drawer boxes will find this slide hits a gap that most undermount lines leave open: high capacity in a concealed, soft-close package sized for thick-sided material. It suits homeowners replacing slides in existing face-frame cabinetry who are already building or sourcing 3/4 inch drawer boxes, and it suits designers specifying a premium undermount for traditional-style kitchen or pantry projects where pull hardware is present but a quiet, controlled close is still the goal.

The Right Slide For Thick-Sided Face-Frame Drawers

When the job calls for a full-extension, soft-close undermount in a face-frame cabinet with 3/4 inch drawer sides and real weight to carry, the Progressa+ covers the spec without compromise — order one pair per drawer and confirm your bracket and locking-device needs before the job starts.
