21" F70 Full Extension Push-to-Open Undermount Drawer Slide Frameless Salice G7U6P533CXB

Push-to-Open Undermount Slides for Handle-Less Frameless Cabinetry

The Salice F70 21-inch push-to-open undermount drawer slides bring touch-release convenience to frameless cabinets with a 170 lb load capacity and full-extension travel. Sold as a pair in a zinc finish, these slides suit kitchen, bath, and furniture builds where hardware-free fronts are part of the design plan.

Key Features

• Push-to-open mechanism ejects the drawer at a light press on the handle-less front, no pull required.
• Full extension brings the entire drawer out to the cabinet face, giving clear access to the back of the box.
• 170 lb load capacity per pair handles heavily loaded kitchen and utility drawers with confidence.
• Frameless cabinet design mounts directly to the interior side panel on the standard line-bore grid.
• Fits 1/2 inch to 5/8 inch drawer sides so the slide works with both thinner and standard-thickness drawer stock.
• Zinc finish protects the steel construction through years of indoor service while staying low-profile beneath the box.

Where These Slides Fit the Job

Push-to-open undermounts earn their place on drawers where hardware would interrupt a clean design: slab-front kitchens, integrated appliance panels, and minimalist furniture pieces. With full extension, every inch of the drawer is reachable once open, which matters most in deep base cabinets where contents pile up at the back. The 170 lb capacity keeps this in working territory for pots-and-pans drawers, heavy tool storage, and densely loaded file pulls, not just light accent drawers.

The 21-inch slide length suits standard base cabinet depths. Build the drawer box to the 21-inch nominal length and size the width to leave the required side clearance beneath the box — undermount fit is engineered, not forgiving. The accepted drawer side thickness runs from 1/2 inch to 5/8 inch, covering both lighter engineered stock and the more common 5/8-inch plywood sides used in production shops.

Construction and Finish

The F70 slide body is steel with a zinc finish — the standard corrosion-resistant treatment for indoor cabinet hardware. The zinc coat protects against the humidity cycles common in kitchen and bath environments without adding visible bulk beneath the drawer. Because the slide mounts concealed under the box, the zinc finish stays out of sight in service; its job is longevity, not appearance. The F70 series is Salice's dedicated undermount push-to-open program, so locking devices, front fittings, and motion components within the family are engineered around these runners.

Who Orders These and Why

Cabinet shops running handle-less kitchen programs reach for push-to-open undermounts as a production standard rather than an upgrade, since knob and pull hardware is simply removed from the design. Designers specifying integrated-front kitchens include push-to-open in the hardware schedule from the start. Contractors sourcing for a single bathroom vanity refresh find the full-extension travel especially useful: the entire drawer comes out to the opening, which matters in a narrow bath where reaching to the back of a 3/4-extension drawer is awkward. At 170 lb capacity, the pair is appropriate for nearly any residential application and a solid fit for light commercial work.

These slides are for frameless cabinets. The side panel mounts directly without rear brackets, which keeps the install straightforward on the 32mm system grid. Face-frame cabinet work requires a different configuration.
