This is the left-hand standard front locking device for Blum TANDEM 563 and 569 series undermount slides, with integrated side adjustment so the drawer front can be fine-tuned after the drawer is hung.
On a Blum TANDEM undermount installation, the front locking device is the clip that anchors the drawer box to the slide at the drawer front. Without it, the drawer box is not secured to the slides. The side adjustment built into this model means that once the drawer is clipped in place, you can nudge the front left or right within the +/- 1.5 mm range to close a gap or align a reveal, rather than lifting the drawer out and starting over. Height adjustment adds another axis of correction, so a front that sits slightly low or high relative to its neighbors can be trued without shimming. This device handles the left side of the drawer; the right-hand version is a separate item.
The locking device is molded plastic, which keeps the clip light and allows the snap-in and snap-out action that makes drawer removal quick during installation and servicing. The plastic body is sized and toleranced to the TANDEM slide geometry — Blum's locking devices are engineered to a specific slide family, and this one fits the 563 and 569 series only. Do not substitute locking devices from other Blum series, other undermount programs, or other brands; the fit geometry and adjustment travel are series-specific.
Cabinet shops running Blum TANDEM 563 or 569 undermount slides will reach for this device any time a left-hand locking clip is missing, damaged, or needed to complete a new drawer installation. It is also the right call when a drawer front on an existing TANDEM installation has drifted out of alignment and the original clip does not offer side adjustment — swapping in this model adds the lateral fine-tuning that a non-adjustable device cannot provide. Designers and installers specifying TANDEM slides for kitchens and bath cabinetry should count one left-hand and one right-hand device per drawer when ordering accessories.
No. This locking device is made for the TANDEM 563 and 569 series. MOVENTO, LEGRABOX, MERIVOBOX, and TANDEMBOX systems use their own series-specific front fixings that are not interchangeable with this part.
You need one left-hand and one right-hand device per drawer — this listing covers the left-hand side only. Order the matching right-hand version separately to complete the pair.
The side adjustment range is +/- 1.5 mm — enough to close small reveal gaps and align a front with its neighbors without repositioning the drawer box.
This is the side-adjustment version, which provides both the 3 mm height adjustment and the +/- 1.5 mm side adjustment. If you only need height correction, Blum also offers a standard locking device without side adjustment — confirm which version your application requires before ordering.
For TANDEM 563 and 569 installations where a left-hand locking device needs to pull double duty on both height and side alignment, this is the part that keeps the job moving without a teardown.
