Salice Progressa 16" Soft-Close Full Extension 170 lb Undermount Drawer Slide, Zinc, G7E6R400XXF6

A High-Capacity Concealed Runner for Demanding Frameless Drawers

The Salice Progressa+ is a 16 inch full-extension undermount drawer slide for frameless cabinets, combining a 170 lb per pair weight capacity with integrated soft-close in a fully concealed steel runner with zinc finish.

Key Features

• 170 lb weight capacity per pair — puts this slide in heavy-duty territory for an undermount, well above the common 90 to 110 lb class.
• Full extension — the entire drawer box travels out to the cabinet face, giving unobstructed access from front to back.
• Integrated soft-close — a built-in damper catches the drawer near the end of travel and settles it shut without slamming.
• Frameless cabinet design — mounts directly to the interior side panel, no face-frame adapter or rear bracket required.
• Steel construction with zinc finish — functional and corrosion-resistant for years of indoor service, fully concealed beneath the drawer box.

Where the 170 lb Capacity Makes a Difference

Most kitchen undermounts are sized for a loaded utensil or spice drawer — 90 to 100 lb covers that range comfortably. The Progressa+ is the right choice when the drawer itself is heavier: a deep pot-and-pan pull-out packed with cast iron, a file drawer carrying hanging folders plus loaded dividers, or a pantry roll-out holding canned goods across its full 16 inch depth. At 170 lb per pair, the slide keeps those drawers running smoothly through years of daily cycles rather than straining at the upper edge of a lighter-rated slide's spec. The 16 inch nominal length also suits shallower base cabinets and smaller drawer sections where the shorter run still needs full rear access.

Construction and Finish

The Progressa+ is built from steel with a zinc finish — a practical combination that protects the slide through continuous indoor use without adding unnecessary bulk under the drawer box. Because the runner mounts beneath the box and stays hidden when the drawer is open, the finish is there to resist wear and corrosion in service, not to be seen. The soft-close mechanism is integrated into the slide body rather than added on, which keeps the profile clean and eliminates separate damper accessories. The drawer box must be built to Salice's published specification for the Progressa series — including the correct box width, side thickness, bottom recess, rear notch, and the drilling required for the Salice series-specific front locking devices.

Who This Slide Is Built For

Production frameless cabinet shops and custom builders who regularly work with heavier drawer loads will find the Progressa+ a direct fit. It closes the gap between a standard 100 lb undermount and a dedicated pantry or heavy-duty pull-out system, without requiring a completely different hardware platform. Designers specifying handle-less frameless kitchens with deep, fully loaded drawers — think appliance garages, heavy-duty junk drawers, or workshop cabinets — can count on the soft-close and full extension without compromising on capacity. This slide is for frameless cabinets only; for face-frame work, a face-frame configured undermount is the correct choice.

The Right Undermount When Load Is the Variable

When drawer weight is the constraint that a standard undermount cannot meet, the Salice Progressa+ in the 16 inch length gives frameless cabinet work full extension, silent soft-close, and a 170 lb per pair capacity in one concealed runner.
