Salice Progressa+ 21" Soft-Close Full Extension Undermount Drawer Slides, Zinc - G5U6S533CXF6

Salice Progressa+ 21 Soft-Close Undermount Slides

Salice Progressa+ 21 soft-close undermount slides are full extension drawer runners that support drawers built with 13 mm to 16 mm material thickness, so they fit a common range of modern cabinet drawer box constructions. The synchronized mechanism coordinates movement between both runners, which helps the drawer glide out smoothly without racking when loaded on one side during everyday use. Their true progressive action with rack and pinion motion controls the opening and closing travel, which helps deliver a consistent feel from start to finish on every cycle. A 100 lb dynamic load rating means the slides are designed to operate under significant working loads, while the 120 lb static rating supports heavier stored contents at rest. The slides are 100% made in Italy, which identifies their origin for projects that specify European-made hardware. Salice America offers these runners in a zinc finish for use on many cabinet interiors.

Key Salice Undermount Slide Advantages

• The full extension drawer runner design lets drawers travel their full length, which improves access to stored items at the back without pulling items out over the front edge.
• The synchronized mechanism keeps both sides of the drawer moving together, which helps reduce side-to-side play when the drawer is opened quickly or loaded unevenly.
• True progressive action with rack and pinion motion manages the transition from closed to fully open, which supports a controlled feel that is useful in higher-use cabinets.
• The 100 lb dynamic load capacity supports active opening and closing under substantial weight, which suits drawers holding tools, cookware, or dense materials.
• The 120 lb static load capacity supports heavier contents when the drawer is at rest, which helps the slide system carry stored load without stressing the runners.
• Meeting and exceeding ANSI BHMA A156.9-2020 Grade 1 offers a defined performance benchmark, which helps align projects to hardware built for demanding use cycles.

Adjustment And Fit For Drawer Installation

This undermount drawer slide system provides height adjustment of plus 2.5 mm, which helps align drawer fronts vertically with adjacent fronts after the drawer box is installed. Side adjustment of plus or minus 1.5 mm lets the installer fine-tune gaps between drawer fronts, which is useful for achieving consistent reveals in a bank of drawers. Depth adjustment of plus or minus 3 mm helps move the drawer front in or out relative to the cabinet face, which supports flush alignment with doors or surrounding trim. The drawer runner works with drawer material thickness from 13 mm to 16 mm, allowing use across several common side material choices while maintaining the slide engagement.

Using These Slides In Cabinet Projects

Where Salice Progressa+ Slides Are Applied

These Salice America undermount drawer slides belong to the "Drawer Slides & Accessories|Slides, Undermount" category, placing them in cabinet and furniture drawer applications that call for concealed runners. The 21 inch slide length matches typical medium-depth base cabinet drawers, which fits many kitchen, bath, and shop layouts where access to full drawer depth matters. Their soft-close function is described in the product name, indicating that the drawer motion is designed to slow near the end of travel, which reduces slamming in day-to-day operation. The slides serve as a full extension runner system under the drawer box, which leaves the drawer sides clear for clean interior construction and hardware-free appearance.

The 100 lb dynamic load and 120 lb static load ratings support use in drawers that carry substantial stored weight, which suits installations handling hardware bins, parts, or dense household items while still operating within the rated range. Meeting and exceeding ANSI BHMA A156.9-2020 Grade 1 positions these slides for demanding environments, which is relevant for cabinetry that experiences frequent opening cycles. Being 100% made in Italy identifies a consistent manufacturing source, which matters to shops standardizing on a single hardware line across multiple jobs.

Why The Adjustment Range Supports Consistent Results

The height adjustment of plus 2.5 mm allows the drawer front to be raised relative to the slide position, which helps correct for small construction tolerances in cabinet openings without rebuilding the drawer box. With side adjustment of plus or minus 1.5 mm, the installer can center the drawer front between face frame stiles or adjacent fronts, which simplifies achieving parallel lines across stacked drawers. Depth adjustment of plus or minus 3 mm enables tuning of how far the front sits from the cabinet face, which can align the drawer front with overlay doors or surrounding panels.

The specified 13 mm to 16 mm drawer material thickness range defines how the drawer sides engage the undermount hardware, which guides drawer box construction so the locking and support points sit properly. The synchronized mechanism and progressive rack and pinion action support repeatable motion across multiple drawers on a project, which is helpful when a job uses many identical openings that all need the same feel. Having clearly defined load ratings and a Grade 1 standard simplifies planning for where these slides are deployed in a cabinet run, which supports consistent performance across service drawers, storage drawers, and heavier-use locations.
