Salice Progressa+ 15" Push-to-Open Full Extension 170 lb Undermount Drawer Slide, Zinc, G7U9P381XXF6

Undermount Slide For Handle-Less Face-Frame Cabinets With Thick Drawer Sides

The Salice Progressa+ 15 inch push-to-open undermount slide is a full-extension, concealed runner built for face-frame cabinets with 3/4 inch drawer sides. Rated 170 lb per pair, it serves handle-less fronts where a pull or knob is not part of the design — a press on the front ejects the drawer, and the slide carries it out to full extension.

Key Features

• Push-to-open mechanism ejects the drawer with a light press on the handle-less front, no hardware required on the face.
• Full extension brings the complete 15 inch drawer out to the cabinet face for access to everything inside.
• 170 lb capacity per pair puts this slide in heavy-duty territory, well above the standard 90 to 100 lb undermount range.
• Face-frame cabinet version is engineered for traditional American face-frame construction with matching rear mounting bracket support.
• 3/4 inch (19mm) drawer side compatibility makes it the correct choice for boxes built from 3/4 inch hardwood or plywood.
• Steel construction with zinc finish for durable, long-term indoor service concealed beneath the drawer box.

Where This Slide Fits the Job

Face-frame cabinetry and a 3/4 inch drawer box together narrow the field considerably — most undermount lines are optimized for 5/8 inch material, and face-frame installs add the rear bracket requirement on top of that. The Progressa+ face-frame version solves both at once. This 15 inch length suits shorter drawers: spice pull-outs, narrow base cabinet drawers, and bathroom vanity drawers where the cabinet is shallow. The push-to-open motion fits any layout where the designer has eliminated visible hardware from the front — modern shaker kitchens with inset-style fronts, built-ins, and bath vanities where a clean face takes priority.

At 170 lb per pair, the capacity here goes beyond what most undermounts in this size range offer. That headroom matters on drawers that carry real weight: a vanity drawer loaded with toiletries, a kitchen drawer packed with cookware, or any application where the box is built from heavier 3/4 inch stock and the contents follow.

Construction and Finish

Steel members with a zinc finish handle the demands of daily cycling indoors. Because the Progressa+ mounts beneath the drawer box and stays hidden when the drawer is open, the finish is functional rather than decorative — it protects the steel and stays out of sight. The 3/4 inch side-thickness version is a distinct model from the 5/8 inch (16mm) Progressa+ variants; the box-width formula, locking device fit, and spacing all correspond to the 19mm material. Do not substitute the 5/8 inch version here — the two are not interchangeable.

Who Orders This Slide

Cabinet shops building traditional face-frame kitchens with handle-less fronts are the primary buyer. The combination of face-frame compatibility, 3/4 inch material fit, and 170 lb capacity at a 15 inch length is a specific configuration that custom and semi-custom shops reach for when the job calls for it. Designers specifying handle-less cabinetry on face-frame boxes will find this the direct answer — no adapter, no workaround. For frameless construction or 5/8 inch material, other Progressa+ variants in the family cover those configurations.
