Salice F70 18" Push-to-Open Full Extension 170 lb Undermount Drawer Slide, Zinc, G7U6P457XXF6

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

The Salice F70 18 inch push-to-open undermount drawer slide is a full-extension, concealed runner built for handle-less drawer fronts in face-frame and frameless cabinets. At 170 lb capacity per pair, it covers loads that standard undermounts cannot, while the mechanical push-to-open mechanism keeps the look hardware-free from front to back.

Key Features

• Push-to-open mechanism ejects the drawer with a light press on the handle-less front, no pulls or knobs required.
• 170 lb weight capacity per pair puts this slide well into heavy-duty territory for an undermount runner.
• Full extension brings the entire 18 inch drawer out to the cabinet face so every inch of interior is reachable.
• Face-frame and frameless compatibility means it works in traditional American cabinetry as well as European-style frameless boxes.
• Fully concealed beneath the drawer box so only wood is visible when the drawer is open.
• Steel construction with zinc finish for reliable indoor service.

Where This Slide Earns Its Place

This is the right slide when two things are true at once: the design calls for handle-less fronts and the drawer will carry real weight. A kitchen base drawer loaded with cast iron, a deep utility pull-out stacked with tools, a pantry drawer holding canned goods — these are the jobs where a standard 90 to 100 lb undermount starts to feel underspecified. The F70's 170 lb per pair rating gives a comfortable working margin on drawers that see heavy, everyday use. Pair that with full extension and the entire contents of the box are within reach, not just the front half.

Because this version fits both face-frame and frameless cabinets, it works equally well in a traditional kitchen build with solid wood frames and in a frameless production run. That dual-construction compatibility makes it a practical stock item for shops that work across both cabinet styles.

Materials, Finish, and Closing Behavior

The F70 is built from steel with a zinc finish — a functional, corrosion-resistant surface suited to indoor cabinet environments. The slide runs concealed beneath the drawer box, so the finish is not decorative; it is there for long-term durability in the closed space under the box.

One thing to be clear on: this is a mechanical push-to-open slide. The drawer opens with a press and closes without a damper. There is no soft-close function on this model. If a damped, silent close matters for the application, the soft-close version of the F70 is the right choice instead. Do not expect both push-to-open and soft-close from this slide — on the F70 line, those are separate models.

Who Spec This Slide

Cabinet shops building handle-less modern kitchens in face-frame construction reach for this slide when the design budget allows premium hardware but the structural framework is traditional. Designers specifying high-capacity undermounts for pantry or utility drawers will find the 170 lb rating gives a margin that the standard 100 lb class does not. Contractors installing base cabinets in commercial or high-use residential settings benefit from the face-frame compatibility without sacrificing the clean, hardware-free look. For boxes built with 1/2 to 5/8 inch drawer sides, this is the F70 version to order.

The Right Slide for Handle-Less Work That Carries Weight

When the job combines a clean, pull-free look with drawers that need to handle serious loads in face-frame or frameless cabinetry, the Salice F70 18 inch push-to-open slide delivers both without compromise.
