This is the right-hand standard front locking device for Blum's TANDEM and TANDEM plus BLUMOTION undermount slide series — the plastic clip that fastens the drawer box front to the slide and sets the left-right starting position of the drawer.
Every TANDEM undermount drawer needs two front locking devices — one on each side — to anchor the drawer box at the front of the slides. Without them, the drawer box simply rests on the slides but is not locked into its adjusted position. This right-hand device clicks onto the right-side slide member and, together with the left-hand device, creates the fixed front connection that keeps the drawer aligned and seated during daily use. The 3 mm height adjustment range means small vertical corrections are possible after the drawer is installed, which is the typical fine-tuning step at the end of a cabinet installation.
The clip body is molded plastic — the same material class Blum uses across its TANDEM locking device line. Plastic here is deliberate: the clip is engineered to flex for tool-free drawer removal while holding the drawer firmly during normal use. It is an indoor cabinetry component and is not intended for wet, exterior, or corrosive environments.
Cabinet shops running TANDEM or TANDEM plus BLUMOTION undermount slides reach for this part in two situations: completing a new build where locking devices were not included with the slide order, or replacing a damaged clip on an existing installation. Because locking devices are handed and series-specific, the right-hand device is always a separate line item from the left-hand version — ordering two of this SKU will not make a working pair. Designers and contractors specifying TANDEM-based cabinetry should confirm the slide series before ordering; the standard locking device fits the 563 and 569 series but does not cross over to MOVENTO or other Blum undermount families.
You need two per drawer — one right-hand and one left-hand device. This listing is for the right-hand clip only; add the left-hand version separately to complete the pair.
Yes. The standard locking device is compatible with both the TANDEM 563 and TANDEM plus BLUMOTION 569 series undermount slides.
No. Blum locking devices are series-specific. This device fits the TANDEM 563 and 569 series only — it will not seat correctly on MOVENTO or other Blum undermount families.
The built-in height adjustment range is 3 mm, which covers the typical fine-tuning needed after a drawer front is hung.
A missing or damaged front locking device leaves the drawer box unseated at the front — replacing this right-hand clip is a straightforward fix that puts the drawer back where it belongs.
