The MuV+ 1-D Locking Device Set is the clip-and-lever pairing that fastens drawer boxes to Knape and Vogt's MuV+ undermount slide system, with one-directional height adjustment and a distinctive blue finish that makes color-coded cabinet layouts easy to manage. Each box contains 60 pairs — one left-hand and one right-hand locking device per pair — covering a high-volume install run in a single order.
Front locking devices are the link between the drawer box and the slide — without them, an undermount installation is not complete. On the MuV+ system, the locking device snaps under the drawer box front, locks the box onto the slide, and provides the one axis of field adjustment the system allows. The blue finish on this version serves a practical purpose beyond aesthetics: in a shop producing cabinets with varied drawer heights or in an install with multiple drawer types, color-coded clips let a crew member confirm at a glance which drawers have been fitted and adjusted without pulling each one. That kind of visual shorthand reduces errors on large multi-drawer projects — kitchen runs, office casegoods, or built-in storage walls where dozens of drawers go in at once.
The locking devices are molded plastic, which is the correct material for this component: lightweight, precisely formed to the MuV+ slide geometry, and durable through the daily open-close cycle of a drawer that sees years of use. The lever release allows tool-free drawer removal for cleaning, transport, or site adjustment. The +3 mm height adjustment is a single-direction (1D) trim that moves the drawer front vertically at the clip — enough to align a front that has settled slightly off level or to compensate for minor box-to-opening variation. It does not adjust side-to-side or in-and-out; those dimensions are set during installation.
This box is sized for cabinet shops, installers, and contractors who build or fit MuV+ undermount drawers in volume. At 60 pairs, it covers 60 drawers — enough for a substantial kitchen or a full run of office casework. The blue finish makes this version a good choice when a shop wants to distinguish a production batch, mark a specific drawer height class, or simply keep locking device inventory organized by color across a warehouse shelf. Homeowners completing a single cabinet repair should confirm the quantity is appropriate before ordering; this is a production pack.
No. MuV+ locking devices are engineered specifically for the MuV+ undermount slide system. They are not compatible with Blum, Grass, Hettich, or other undermount systems, and should not be substituted across brands.
The mechanism, adjustment range, and system compatibility are identical across colors. The blue finish is for visual identification — useful in color-coded workflows or multi-drawer installations where distinguishing clips by zone or height class saves time.
Yes. Each pair contains one left-hand and one right-hand locking device. A box of 60 pairs gives you both members for 60 drawers.
The 1D designation means one direction: height only. The +3 mm of adjustment moves the drawer front up vertically. Side-to-side and depth positioning are set at installation, not through the locking device.
Yes. The lever-release design lets you lift the drawer off the slides and reseat it repeatedly. The locking devices stay on the slides and do not need to be replaced on normal removal.
Stocking the right locking devices before a cabinet run starts means no mid-project delays hunting for the correct clip — and the blue color makes it easy to pull the right box off the shelf the first time.
