18 Inch Undermount Drawer Slide for Face-Frame Cabinets with 3/4 Inch Drawer Sides

The Salice Progressa is an 18 inch full-extension undermount drawer slide built specifically for face-frame cabinets and drawer boxes with sides up to 3/4 inch (19mm) thick. Soft-closing, concealed beneath the box, and rated 120 lb per pair, it fills a precise gap in the undermount market: full-extension performance for the traditional American cabinet construction style that 3/4 inch solid-wood or plywood boxes call home.

Key Features

• Full extension brings the entire drawer out to the cabinet face, putting every inch of the box within reach.
• 120 lb capacity per pair handles heavily loaded drawers in kitchen, bath, and utility cabinetry.
• Integrated soft-close catches the drawer near the end of travel and settles it shut without a slam.
• Face-frame cabinet design makes this slide the correct choice for traditional American cabinetry, not a universal fit.
• 3/4 inch (19mm) maximum drawer side thickness matches solid-wood and thick-plywood drawer box construction.
• Steel construction with bright zinc-plated finish delivers lasting performance in dry indoor installations.

Where This Slide Belongs in the Job

Face-frame cabinetry is the dominant construction style in American residential kitchens, and shops building those cabinets often run drawer boxes from 3/4 inch hardwood or Baltic birch plywood. Most undermount slides are engineered for 5/8 inch (16mm) drawer sides — a box cut from 3/4 inch stock will not seat correctly on them. The Progressa is the version of the line built for that thicker material, which means it is the right call for maple dovetail boxes, thick-wall plywood drawers, and custom shop builds where 3/4 inch stock is the house standard.

In a face-frame cabinet, the slide's rear end needs support behind the frame. The Progressa face-frame version accommodates that requirement through series-specific rear mounting brackets. Those brackets are not universal — they are Progressa-specific — so specify them when ordering for face-frame work.

Build and Finish

The Progressa is made from steel with a bright zinc-plated finish, a functional treatment that protects the slide through years of indoor service. Because the slide mounts beneath the drawer box, the finish is almost entirely hidden once the drawer is in place — it serves corrosion resistance, not appearance. The 18 inch nominal length suits standard base cabinet drawer applications and must match the drawer box built to Salice's published specification for this series, including the correct box-width formula, bottom recess, rear notch, and drilling for the Progressa's front locking devices.

Who Reaches for the Progressa

Custom cabinet shops with a 3/4 inch drawer-box standard find the Progressa's 19mm side-thickness rating eliminates the need to thin stock or switch materials to run a concealed slide. Contractors installing traditional face-frame kitchens get the clean, concealed look of an undermount runner without compromising on drawer side material. Designers specifying premium hardware for a renovation with existing face-frame carcasses can call out this slide knowing it suits the construction. At 120 lb per pair with full extension, it handles everything from a lightly stocked spice drawer to a loaded pots-and-pans pull-out in the same run.
