This is a matched left-hand and right-hand locking device set for Hettich Quadro undermount drawer slides, designed to secure wood drawer fronts to boxes built with 5/8 inch (16mm) sides. The set arrives in Black, pairing hardware-invisible function with a finish that disappears against dark cabinet interiors.
Quadro locking devices lock the drawer box onto the undermount slide at the front and hold the front panel in place with a tool-free snap. They are the connection point between the slide system and the finished face of the drawer. Without the correct locking device, the drawer box will not seat on the slide or release cleanly for removal. In a dark cabinet interior — think a modern handleless kitchen with black-finished interiors or a media unit with a consistent dark palette — the Black finish means the hardware stays visually quiet even when the drawer is fully open.
The clips are molded in plastic and finished in Black. Plastic construction keeps the clips light while delivering the snap-fit retention and adjustment range the Quadro system requires. The Black colorway suits installations where the interior of the cabinet is visible through the open drawer and finish consistency matters to the designer or homeowner specifying the job.
Cabinet shops running Hettich Quadro slides on dark-finished or black-interior frameless cabinets will find the Black version the natural finish match for their build. Designers specifying a consistent hardware palette for a handleless kitchen will appreciate that the locking devices reinforce rather than interrupt the interior color story. These clips are also the right reorder unit for a shop that needs to replace a clip on an existing Quadro installation with 5/8 inch drawer sides — order by the drawer, one set per opening.
The clips attach to the Quadro slide's front end and to the drawer front — the cabinet construction type is primarily a factor in how the slides themselves are mounted, not in how the locking devices fit. Confirm your Quadro slide version supports the front-fixing method used in your build.
No. This set is engineered for 5/8 inch (16mm) maximum drawer side thickness. If your boxes run 3/4 inch (19mm) sides, you need the version specified for that thickness.
No. Quadro locking devices are Quadro-specific. They will not seat or function correctly on slides from other brands or other Hettich series.
The clips offer +2 mm of upward height adjustment, letting you true the drawer front after hanging without pulling the drawer.
A correct locking device is what turns a mounted slide into a finished, functioning drawer — and in a dark-interior build, the Black finish makes sure the hardware stays part of the design rather than a distraction from it.
