Zinc Undermount Drawer Slide Built for Face-Frame Cabinetry

The Knape and Vogt Samet 18 inch soft-close undermount drawer slide is a concealed, full-extension runner engineered for face-frame cabinet construction, carrying drawer boxes with sides up to 5/8 inch thick and rated 66 lb per pair.

Key Features

• Face-frame cabinet fit — designed specifically for traditional face-frame construction, where the rear of the slide requires proper rear support.
• Full extension — the entire drawer comes out to the cabinet face, putting the back of the box within reach.
• Integrated soft-close — a built-in damper slows the drawer to a quiet, controlled close in the final inch of travel.
• 66 lb capacity per pair — suited to everyday cabinet drawers in kitchens, baths, and casework.
• Zinc-finished steel construction — a functional, corrosion-resistant finish that holds up through years of indoor service.

Where This Slide Belongs in Your Build

Face-frame cabinetry presents a specific challenge for undermount slides: the cabinet side is recessed behind the face frame, so the rear of the slide needs rear mounting brackets to stay properly supported. This Samet slide is designed for exactly that condition. It suits traditional American face-frame cases in kitchens, bathroom vanities, and built-in furniture where a concealed runner is specified but the box is framed rather than frameless. At 66 lb per pair, it handles everyday kitchen and bath loads without overshooting the budget. If the same job calls for heavier duty — waste pull-outs, wide pots-and-pans drawers, or anything above 66 lb — step up to a higher-capacity undermount in the Samet or KV MUV program.

Construction and Finish

Steel members with a zinc finish give this slide its corrosion resistance for interior cabinet environments. Because the slide mounts beneath the drawer box and stays concealed when the drawer is open, the zinc finish serves a protective rather than decorative function — it will not be visible in day-to-day use. The integrated soft-close damper is built into the slide body, so there is no separate add-on mechanism to install or adjust.

Box Specification and Cabinet Construction

This slide is engineered for drawer sides up to 5/8 inch (16mm) thick. The drawer box must be built to the Samet series specification for the 18 inch nominal length — correct box width, bottom recess, rear notch, and locking-device drilling. Face-frame installs require matching rear mounting brackets to support the slide's back end behind the frame; those brackets are series-specific and should be ordered alongside the slides. Front locking devices complete the installation and hold the drawer box to the slide at the front — confirm whether locking devices are included or need to be ordered separately for this SKU before placing the order.

Concealed Performance Where the Frame Is the Starting Point

When the job is face-frame construction and the spec calls for a clean, hidden runner with soft-close at a practical capacity, this 18 inch Samet slide fits the work — build the box to spec, add the rear brackets the face frame requires, and the drawer runs quietly out of sight.
