King Slide 6-Pair Box 18" Soft-Close Full Extension 75 lb Undermount Drawer Slide, Zinc, 280-943

Soft-Close Undermount Slide For Face-Frame and Frameless Cabinets, With Clips Included

The King Slide 18 inch soft-close undermount drawer slide is a full-extension, concealed runner for 5/8 inch drawer sides — sold as a pair with locking clips included so the basic install hardware ships with the slide.

Key Features

• Front locking clips included — the clips that fix the drawer box to the slides ship in the box, no separate accessory order required.
• Full extension — the entire drawer travels out to the cabinet face, giving complete access to the back of the box.
• Integrated soft-close — a built-in damper catches the drawer near the end of travel and settles it shut quietly.
• 75 lb capacity per pair — sized for standard kitchen, bath, and furniture drawers.
• Fits both face-frame and frameless cabinets — one model covers the two most common cabinet constructions.
• Steel construction with zinc finish — durable for years of indoor service, hidden beneath the drawer box.

Where This Slide Fits the Job

This is the right slide for shops and installers who want concealed, full-extension movement in everyday kitchen and bath work. At 75 lb per pair, it handles a loaded silverware drawer, a bathroom vanity pull-out, or a bedroom dresser drawer without issue. Because it suits both face-frame and frameless construction, a single SKU covers the mixed cabinet types that show up on many residential renovation projects. The 18 inch nominal length targets the most common drawer depth in base cabinet runs, and the minimum installation depth of 21 inches means the slide fits a standard 24-inch-deep base without crowding the back wall.

Materials, Finish, and Build

The slide body is formed steel with a zinc finish — a functional, corrosion-resistant coating suited to the indoor environment where it will live, completely out of sight beneath the drawer box. The built-in soft-close damper is integrated into the slide mechanism itself, not an add-on part, so there is nothing to lose during installation and no secondary adjustment after the drawer is hung. The zinc finish blends into the cabinet interior without competing with the visible hardware on the drawer front.

Matching the Slide to Your Build

This slide is engineered for drawer sides up to 5/8 inch (16mm) thick — the standard dimension for dovetailed and doweled shop boxes. Build the drawer box to King Slide's published specification for this series: nominal 18 inch length, the correct box width for the side clearance, a bottom recess, a rear notch, and the drilling required by the included locking clips. In face-frame cabinets, the rear of the slide needs support — add the appropriate rear mounting brackets for the series, which are sold separately. Frameless installs fasten the slide directly to the cabinet side panel. Designers specifying handle-less fronts should note that this is a soft-close model, not a push-to-open model; a separate push-to-open configuration is available in the King Slide line if a touch-open front is the goal.

One Pair, Ready to Install

With clips in the box and compatibility across both face-frame and frameless construction, this slide simplifies ordering on mixed-cabinet projects — match the length to your drawer, build the box to spec, and add rear brackets for any face-frame runs.
