Salice Progressa+ 18" Push-to-Open Full Extension 170 lb Undermount Drawer Slide, Zinc, G7U9P457CXF6

Undermount Drawer Slide For Thick-Sided, Handle-Less Drawer Builds

The Salice Progressa+ 18 inch push-to-open undermount slide is a full-extension concealed runner engineered for frameless cabinets with drawer sides up to 3/4 inch thick. At 170 lb per pair, it carries oversize and heavily loaded drawers that outpace standard undermount capacity, and its push-to-open mechanism removes the need for pulls or knobs entirely.

Key Features

• Push-to-open mechanism ejects the drawer with a light press on the handle-less front, no hardware required.
• Full extension brings the entire 18 inch drawer box out to the cabinet face so every inch of the interior is reachable.
• 170 lb weight capacity per pair covers oversize, heavily loaded, and wide drawer applications well beyond the standard undermount class.
• 3/4 inch (19mm) drawer side compatibility makes this the correct Progressa+ model for shops building from thick hardwood or plywood stock.
• Frameless cabinet design mounts directly to the cabinet side panel for a clean, flush installation on modern casework.
• Steel construction with zinc finish provides lasting corrosion resistance through years of indoor service.

Built for Handle-Less Fronts and Heavy Loads

The push-to-open mechanism is the defining choice here: a light press on the drawer face triggers the release, so the front stays completely clean. This is the right motion configuration for modern slab-front kitchens, integrated appliance panels, and anywhere hardware would interrupt a flush surface. Because this model is the mechanical push-to-open version, closing is direct, without a damper. If a damped, silent close is a priority for the application, a soft-close Progressa+ model is the alternative — these two functions are separate configurations in the line.

Steel, Zinc, and a Rating Built for Real Weight

Steel members with a zinc finish make up the slide body, protecting the mechanism through daily cycling in indoor cabinetry. The 170 lb per-pair rating moves this slide into heavy-duty territory — well above the 90 to 100 lb range common to standard undermounts — which makes it a practical fit for wide pots-and-pans drawers, utility pull-outs, and any application where the drawer box and its contents add up to real weight. Because the slide mounts entirely beneath the drawer box, the finish is functional rather than decorative; it stays concealed in use.

Who Specifies This Slide

Cabinet shops building frameless kitchens from 3/4 inch hardwood or Baltic birch drawer stock will find this slide sized for their material without compromise. The 18 inch nominal length suits standard base cabinet drawer depths, and the 170 lb capacity gives production specifiers room to cover a wide range of drawer applications with a single model. Designers planning handle-less kitchens — where every visible face is a flush panel — rely on push-to-open undermounts to keep that look consistent across every drawer in the run. The Progressa+ is also a reasonable specification for accessibility-focused installations where operating a pull requires extra effort.

The Right Slide Keeps the Job Moving

Pair this 18 inch Progressa+ push-to-open slide with 3/4 inch drawer stock in a frameless cabinet, build the box to Salice's published specification, and the handle-less front works exactly as designed — no extra hardware, no compromise on capacity.
