The Knape and Vogt MUV34B 18 is an 18-inch soft-close full-extension undermount drawer slide built for drawer boxes with 3/4-inch sides. Sold as a pair, it suits both face-frame and frameless cabinet construction and carries a 75 lb load rating per pair.
An 18-inch undermount slide is the right call when the cabinet interior depth supports it and the drawer needs to clear fully for access to the back. Kitchen utility drawers, bathroom vanity drawers, and base-cabinet drawers in furniture-grade cabinetry are all natural fits. Because the slides mount beneath the box and fasten with front locking devices, nothing shows when the drawer is open — a clean look that matters in visible installations. In face-frame cabinets, the rear of each slide needs rear mounting support; plan for that hardware before the install. In frameless construction, the slides mount directly to the panel sides on the cabinet's system-hole layout.
The MUV34B 18 is a steel slide with a zinc finish — a practical, durable choice for a component that lives hidden beneath the drawer box. Zinc plating protects the steel through years of indoor use without adding visible hardware to the cabinet interior. The slide is engineered for 3/4-inch drawer sides, which is the standard thickness for drawer boxes built from solid wood or plywood stock. The drawer box must be built to the MUV series specification for box width, side thickness, and any required rear notching or locking-device drilling — an off-spec box will not seat correctly on an undermount slide.
Cabinet shops running 3/4-inch drawer boxes will find the MUV34B 18 slots into a standard production workflow: build the box to spec, set the slides, and snap the front locking devices. The full-extension travel and soft-close close make it a strong residential specification for designers and contractors who need quiet, accessible drawers without moving up to a premium-priced system. Homeowners tackling a kitchen refresh or vanity rebuild will find the face-frame and frameless compatibility useful if the existing cabinets are an older framed style or a newer Euro-box design.
Yes. In face-frame construction the cabinet side is set back from the frame, so the rear of the slide needs support. Add the appropriate MUV-series rear mounting brackets — sold separately — before installing in a framed cabinet.
No. This version is engineered specifically for 3/4-inch drawer sides. Knape and Vogt offers separate MUV models sized for 5/8-inch sides; confirm the side thickness of your drawer box before ordering.
A full-extension slide brings the drawer member out approximately the full slide length, so the entire drawer interior clears the cabinet face. This is different from a 3/4-extension slide, which leaves the back few inches of the drawer inside the cabinet.
The integrated damper catches the drawer in the final inch of travel and slows it to a controlled, silent close. A standard slide without soft-close lets the drawer coast or snap shut on its own momentum. This is damped soft-close, not a self-closing ramp — the difference matters in terms of noise and feel.
The MUV34B 18 is sold as a pair — one complete set of slides for one drawer. The 75 lb load rating is also stated per pair.
The MUV34B 18 brings full-extension travel and integrated soft-close to drawers built on 3/4-inch stock, in a concealed undermount format that works across face-frame and frameless cabinets — a versatile slide that earns its place in a shop's standard offering.
