170 lb Capacity And 3/4 Inch Drawer Sides: Built for the Drawers That Work the Hardest

The Salice Progressa+ 27 inch undermount slide is a full-extension, soft-close concealed runner engineered for frameless cabinets with 3/4 inch drawer sides — and rated at a substantial 170 lb per pair, it belongs on the jobs where standard undermounts are undersized.

Key Features

• 170 lb weight capacity per pair — puts this slide well above the common 90 to 110 lb class, handling oversized and heavily loaded drawers with room to spare.
• Full extension — the entire 27 inch drawer comes out to the cabinet face, giving complete access to the back of the box.
• Integrated soft-close — a built-in damper catches the drawer near the end of travel and settles it shut without slamming.
• 3/4 inch (19mm) drawer side compatibility — engineered specifically for boxes built from 3/4 inch material, not the more common 5/8 inch version.
• Frameless cabinet installation — mounts directly to the cabinet side panel, no face-frame adapter or rear bracket required.
• Steel construction with zinc finish — functional corrosion protection for long indoor service life, concealed beneath the drawer box.

Where This Slide Earns Its Rating

At 27 inches, this runner is sized for the deeper base cabinets common in kitchen runs, pantry sections, and utility cabinetry. The 170 lb per pair rating makes it the right call for pots-and-pans drawers, heavy cutlery banks, shop supply pull-outs, and any application where a standard undermount would be operating near its ceiling. The full-extension travel means nothing stays buried in the back — the whole drawer box presents itself at the cabinet face when opened. For frameless builds using 3/4 inch plywood or hardwood drawer sides, this is the undermount that matches the material without requiring a step up to a specialty slide.

Construction and Finish

Steel members with a zinc finish give the Progressa+ the corrosion resistance needed for indoor service without adding unnecessary bulk. Because the slide mounts concealed beneath the drawer box, the finish stays out of sight in daily use — its job is protection, not aesthetics. The integrated soft-close mechanism lives inside the slide body, so there are no external damper attachments to install or replace. Build the drawer box to Salice's published specification for the Progressa+ series: 3/4 inch (19mm) sides, correct box width for the required side clearance, bottom recess, rear notch, and the drilling layout for Salice's front locking devices, which are series-specific accessories.

Who Reaches for This Slide

Production cabinet shops running frameless lines with 3/4 inch box stock will find the Progressa+ fits directly into an existing workflow — the side thickness matches the material, and the 27 inch length covers the deeper drawer runs without special ordering. Custom builders specifying kitchen and pantry cabinetry for clients who want concealed hardware and damped closing at above-average load ratings will also find this slide fills a gap that standard undermounts leave open. It is not the economy choice and not the maximum-capacity choice — it sits squarely in the high-performance tier for serious residential and light commercial work.

Frequently Asked Questions

The Right Runner for Heavy, Deep, Frameless Drawers

When the drawer is deep, the box is 3/4 inch stock, and the load calls for more than a standard undermount can reliably carry, the Salice Progressa+ 27 inch slide delivers full extension and soft-close at 170 lb per pair — all hidden cleanly beneath the box.
