Salice Progressa+ 20" Soft-Close Full Extension 154 lb Undermount Drawer Slide, Zinc, G7E6R500XXF6

154 Lb Capacity And Frameless Precision in a 20 Inch Soft-Close Undermount Slide

The Salice Shelf Smove 20 inch undermount drawer slide is a full-extension, soft-close concealed runner built for frameless cabinets and rated at a substantial 154 lb per pair — well above the standard 90 to 100 lb class. It suits production shops and custom builders who need a high-capacity concealed slide in a 20 inch length without stepping up to specialty heavy-duty hardware.

Key Features

• 154 lb weight capacity per pair — handles heavily loaded drawers that standard-class undermounts cannot.
• Full extension — the entire 20 inch drawer box travels out to the cabinet face so the rear is fully reachable.
• Integrated Smove soft-close — a damper catches the drawer near the end of travel and settles it silently shut.
• Frameless cabinet design — mounts directly to the flat cabinet side for clean, efficient installation on Euro-style boxes.
• Steel construction with zinc finish — corrosion-resistant and built for years of indoor service.

Where This Slide Earns Its Place

A 154 lb rating per pair puts this slide in a different bracket than the typical kitchen undermount. It handles the applications where standard-class slides struggle: deep base cabinets loaded with cast iron, pots-and-pans drawers in commercial-adjacent kitchens, wide shop drawers carrying tools, and heavy pantry pull-outs. The 20 inch (500mm) nominal length covers the most common base cabinet depth, and full extension means nothing stays stranded at the back of the box. Because the slide is fully concealed beneath the drawer box, the interior stays clean regardless of how heavy the contents are.

Construction and Finish

Steel members with a zinc finish give this slide durable corrosion resistance through years of indoor cycling. The Smove damper is Salice's integrated soft-close mechanism — engineered into the slide body rather than added on, so the damping is consistent across the rated life of the product. Because the slide mounts underneath and stays hidden when the drawer is open, the zinc finish serves a functional rather than decorative role.

Who This Is For

Custom cabinet shops building frameless kitchens or furniture pieces that need concealed slides without compromising on load capacity will find this a direct fit. It also suits high-end residential renovations where the drawer contents are genuinely heavy and the homeowner expects both silent operation and full rear access. Production builders running 20 inch drawer boxes through a frameless line can stock this slide and get the Smove soft-close behavior at a capacity tier that leaves headroom.

Common Questions

High Capacity, Silent Close, Clean Install

When the drawer contents are heavy, the cabinet is frameless, and the close has to be silent, this 20 inch Salice Shelf Smove slide covers all three — at a capacity that leaves room to grow.
