The Knape and Vogt MUV 18 inch undermount drawer slide is a concealed, full-extension runner with integrated soft-close, made for drawer boxes with 1/2 to 5/8 inch sides and rated 75 lb per pair. It suits both face-frame and frameless cabinet construction in a single model, making it a practical choice for shops and installers working across cabinet styles.
An 18 inch undermount slide suits base cabinets with moderate drawer depth — a common size in kitchen lower cabinets, bathroom vanities, and bedroom or office case goods. At full extension, the drawer opens completely to the cabinet face, which matters whenever the back of the drawer needs to be reachable without pulling the whole box out by hand. The soft-close mechanism is the right call for residential kitchens and client-facing projects where a controlled, silent close is expected. Because the MUV handles both face-frame and frameless installs, shops that build across both cabinet styles can stock a single slide rather than managing two separate lines. For production runs, that simplification reduces the chance of pulling the wrong SKU at the bench.
The MUV slide is built from steel with a zinc finish that protects the members through years of indoor use. The slide runs concealed beneath the drawer box, so the zinc finish serves a functional role rather than a decorative one — it will not be visible once the drawer is installed. The drawer box must be built to Knape and Vogt's published specification for the MUV series: nominal 18 inch length, the correct box width for the required side clearance, a bottom recess, and a rear notch. Front locking devices are series-specific MUV components; confirm whether they are included with this SKU or sold separately before ordering.
This slide is a strong match for cabinet shops and installers who want a clean concealed look and soft-close motion at a working capacity suited to everyday residential drawers. It is not the choice for heavy pantry pull-outs or oversized drawers that exceed 75 lb — step up to a higher-capacity undermount for those applications. For shops building both face-frame and frameless work, the MUV's dual-construction compatibility reduces inventory and simplifies ordering. In face-frame cabinets, plan for the MUV-specific rear mounting brackets to support the back of the slide; these are not universal and do not interchange with rear brackets from other brands or series.
Face-frame installs require rear mounting brackets to support the back of the slide behind the frame. These brackets are MUV-specific and sold separately — they do not interchange with brackets from other slide brands or series.
Confirm the sold-as unit on the product page before ordering. One working drawer requires one left-hand and one right-hand slide.
The drawer box must be built to Knape and Vogt's specification for the MUV 18 inch series, including the correct box width, bottom recess, and rear notch. A box that is not built to spec will not seat correctly on the slides.
No. This model is sized for 1/2 to 5/8 inch drawer sides. For 3/4 inch material, you need the MUV model specified for that thickness — the two versions are not interchangeable.
Locking devices for the MUV system are series-specific. Verify whether they ship with this SKU or are a separate accessory before placing the order — do not substitute locking devices from other brands.
The MUV 18 inch undermount delivers full extension and soft-close in a concealed slide that installs in face-frame and frameless cabinets alike — a straightforward, dependable runner for the drawer depth that shows up most often in residential and light commercial work.
