Salice Progressa+ 21 Inch Undermount Drawer Slides

Salice Progressa+ 21 inch undermount drawer slides provide a full extension drawer runner with a synchronized mechanism for 19 mm (3/4 inch) drawer material thickness, so the drawer travels its entire length while staying aligned under load. The true progressive action with rack and pinion action moves both slides in unison, which helps the drawer open and close smoothly along the whole stroke. The soft-close function is built into this full extension system, so drawers come to a controlled stop. A load capacity of 154 lb dynamic and 170 lb static supports demanding applications where drawers are regularly cycled and occasionally heavily loaded. These slides are 100 percent made in Italy, so all critical components are produced under a single manufacturing standard. The product is classified as an undermount drawer slide, keeping hardware hidden beneath the drawer.

Key Functional Details For Drawer Builders

• The full extension drawer runner design allows the drawer box to travel completely out of the cabinet, so the entire 21 inch depth is accessible for storage and hardware visibility.
• The synchronized mechanism for 19 mm (3/4 inch) drawer material thickness keeps both sides moving together, which helps prevent racking when the drawer is opened with an off-center pull.
• The true progressive action with rack and pinion action engages movement along the full slide length, so the opening force stays consistent from closed to fully open.
• A dynamic load capacity of 154 lb and static load capacity of 170 lb support drawers that carry tools, parts, or dense material, reducing flex in normal use.
• The slides meet and exceed ANSI BHMA A156.9-2020 Grade 1 Standard, so performance levels match a recognized benchmark for cabinet hardware operation.
• The soft-close function operates at the end of travel, so drawers are pulled gently into the cabinet and do not slam against the face frame.

Adjustment And Fit Details For Installers

These undermount drawer slides provide height adjustment of plus 2.5 mm, which lets the installer raise the drawer front slightly to align reveals. Side adjustment of plus or minus 1.5 mm lets the drawer be shifted left or right, dialing in clearances between fronts. Depth adjustment of plus or minus 3 mm helps set the drawer front flush to the face frame or adjacent fronts, using the built-in hardware instead of altering the cabinet. The slides are intended for 19 mm (3/4 inch) drawer material thickness, so drawer box construction can be planned around this fixed side thickness. By combining these adjustments, fine tuning of front gaps can be done without reworking the drawer box.

Using Salice Progressa+ Slides In Cabinet Projects

Where These 21 Inch Slides Are Applied

This product is a Salice America Progressa+ 21 inch soft-close full extension undermount drawer slide, identified by manufacturer part number G7U9S533XXF6, used where the hardware needs to mount beneath the drawer. The undermount drawer slide classification keeps the mechanism under the 19 mm (3/4 inch) drawer material, which supports a clean side profile on the drawer box. A dynamic load capacity of 154 lb and static capacity of 170 lb position these slides for drawers that see frequent opening with substantial contents, such as storage for components or hardware. The full extension drawer runner design lets the back of a 21 inch drawer clear the face frame, which is valuable where items stored at the rear need direct access. Because the slides meet and exceed ANSI BHMA A156.9-2020 Grade 1 Standard, they are suited to projects that call for hardware tested to a specific performance level.

How Slide Adjustments Support Consistent Results

The height adjustment of plus 2.5 mm built into these undermount slides lets installers raise a drawer front slightly, which helps align reveals when face frames or fronts vary a small amount. Side adjustment of plus or minus 1.5 mm allows shifting the drawer box relative to the cabinet opening, which is useful when setting equal gaps between adjacent drawer fronts. Depth adjustment of plus or minus 3 mm helps pull fronts into plane across a run of cabinets, improving the finished appearance without altering drawer construction. The synchronized mechanism paired with true progressive action and rack and pinion action keeps both slides moving together across their travel, which supports parallel alignment when drawers are opened and closed repeatedly. The soft-close feature engages near the end of stroke, bringing the drawer to a controlled close that supports front alignment against the cabinet without impact.
