Salice Progressa+ 18" Push-to-Open Full Extension 170 lb Undermount Drawer Slide, Zinc, G7U9P457XXF6

Push-to-Open Power and a Face-Frame Fit in One Heavy-Duty Concealed Slide

The Salice Progressa+ 18 inch push-to-open undermount slide is a full-extension, concealed runner built for face-frame cabinets and drawer boxes with sides up to 3/4 inch thick. It is rated 170 lb per pair — well above the standard kitchen-class range — and ejects the drawer with a light press on the front, no pulls or hardware required.

Key Features

• Push-to-open mechanism ejects the drawer with a light touch on the front, keeping the cabinet face clean and hardware-free.
• Full extension brings the entire 18 inch drawer box out to the cabinet face for unobstructed access to rear contents.
• 170 lb capacity per pair handles heavily loaded drawers that standard undermounts cannot — well into heavy-duty territory.
• Face-frame cabinet version designed specifically for traditional American cabinet construction with proper rear support geometry.
• 3/4 inch maximum drawer side thickness suits shops building from 3/4 inch plywood or hardwood stock.
• Steel construction with zinc finish for durable, corrosion-resistant indoor service.

Where This Slide Earns Its Place

The combination of push-to-open motion, face-frame construction, and 3/4 inch side compatibility puts this slide in a specific and useful niche. It suits modern, handle-less drawer fronts installed in traditional face-frame cabinetry — a common pairing in transitional kitchen designs where clean slab fronts meet conventionally framed boxes. The 170 lb per pair rating also opens it up to applications where drawer contents are genuinely heavy: deep pots-and-pans drawers, file drawers in face-frame office furniture, or utility pulls loaded with tools or supplies. If the job calls for a handle-less look on a face-frame build and the load demands more than a standard 90 to 100 lb undermount can carry, this is the correct slide to reach for.

Build and Finish

The Progressa+ is built from steel with a zinc finish that protects the members through years of indoor service. Because the slide rides fully concealed beneath the drawer box, the zinc finish is functional rather than decorative — it will not be visible once the drawer is installed. The roller-bearing carriage supports smooth travel at the rated load, and the full-extension geometry ensures the drawer member travels the full nominal length so nothing stays hidden at the back of the box.

Getting the Box and Cabinet Right

This slide is the face-frame version of the Progressa+ line. In face-frame cabinets, the rear of the slide needs proper support — use the matching Progressa+ rear mounting brackets, which are series-specific and not interchangeable with brackets from other Salice lines or other brands. Build the drawer box to Salice's published specification for this series: 18 inch nominal length, the correct box width for the slide's side clearance, bottom recess, rear notch, and drilling for the Progressa+ front locking devices. The push-to-open mechanism also requires a defined front gap between the drawer front and the cabinet face frame — an inset-tight or oversized gap will prevent the trigger from releasing cleanly. Confirm the gap specification in the Salice installation guide before setting the drawer front.
