Salice Progressa 18" Soft-Close Full Extension 100 lb Undermount Drawer Slide, Zinc, G5U6S457CXF6

Zinc Undermount Drawer Slide For Frameless Cabinet Builds

The Salice Progressa+ is an 18 inch full-extension undermount drawer slide with integrated soft-close, built for frameless cabinets with drawer sides between 1/2 and 5/8 inch thick. It runs concealed beneath the drawer box, rated 100 lb per pair, and keeps every drawer in the run closing silently and consistently.

Key Features

• Full extension brings the entire drawer box out to the cabinet face, putting the back of the drawer within easy reach.
• Integrated soft-close catches the drawer near the end of travel and settles it shut without slamming.
• 100 lb capacity per pair handles loaded kitchen, bath, and utility drawers with confidence.
• Frameless-ready design mounts directly to the cabinet side panel for a clean, production-friendly install.
• Steel construction with zinc finish provides reliable indoor durability beneath the drawer box.
• Fits drawer sides from 1/2 to 5/8 inch thick, covering the most common dovetailed and doweled box materials.

Built for Production Frameless Work

Frameless construction puts the slide mounting surface right at the cabinet side panel, and the Progressa+ takes full advantage of that clean line — no face frame to work around, no rear bracket adapters to source. The slide fastens directly to the interior panel and carries the drawer box on concealed runners, so the finished drawer shows only wood. At 18 inches, this length suits standard base cabinet depths and the drawer boxes built for them. Because the slide is full extension, the entire box clears the cabinet opening, which matters when the drawer is holding spice jars, utensils, or anything else that gets pushed to the back.

Steel, Zinc, and the Progressa+ System

Steel members finished in zinc handle the mechanical work quietly and last through years of daily cycling indoors. The zinc finish is functional rather than decorative — the slides stay hidden under the drawer box in use, so what matters is that the finish holds up to the job, not how it looks from across the room. The integrated soft-close mechanism is part of the slide itself, not a bolt-on addition, which means the damping behavior stays consistent across every drawer in the run without additional parts to specify or forget. The drawer box must be built to Salice's published specification for the Progressa+ series: nominal 18 inch length, correct box width for the required side clearance, bottom recess, and rear notch with drilling for the Salice-specific front locking devices. Locking devices are series-specific and do not interchange with other brands or other Salice lines.

Right for Shops Running Frameless Cabinetry

The Progressa+ is a strong fit for cabinet shops producing frameless kitchens, bath vanities, and built-ins where a consistent concealed slide with soft-close is the baseline spec. The 100 lb per pair rating covers the realistic load range for most residential drawers without stepping up to a heavy-duty model. Designers specifying drawer hardware for frameless casegoods get a clean result: no visible hardware when the drawer is open, no slam, and a rated capacity that matches the application. This is an indoor-only slide — the zinc finish suits dry cabinet interiors, not wet or washdown environments.
