Tandem 563/569 locking device is a right-hand standard locking device with side adjustment that secures BP563/569 series runners to the drawer box, which supports a consistent connection point when building or installing Tandem drawers. The device is designed for use with BP563/569 series runners only, so it targets installers working specifically with those Blum systems. One right and one left are required per drawer, which defines how many units are needed when planning a run of cabinets. The right side uses a captive design while the left is self-aligning, so the pair works together to hold the drawer and guide it into proper position. A steel base with synthetic, spring-loaded release levers ties strength and controlled release together, which helps during removal or adjustment of the drawer.
Height adjustment of plus 1/8 inch, or 3.0 mm, is built into the device, giving vertical movement to bring drawer fronts into line with adjacent fronts. Side adjustment of plus 1/16 inch, or 1.5 mm, lets the installer move the drawer sideways, which helps balance reveals and correct slight racking. A minimum inside drawer width of 6-11/16 inches defines the smallest drawer interior this device is intended to work with, so narrower layouts can be evaluated against that figure. For use with BP563/569 series runners only is specified, tying this locking device clearly to that particular runner family during planning and layout.
This Blum right hand locking device with side adjustment is for drawers running on BP563/569 series runners, so it slots into projects already designed around those under-mount slides. As a standard locking device, it connects the runner to the drawer at the front, which is the key point for setting drawer position in the opening. The minimum inside drawer width of 6-11/16 inches sets a threshold for the interior box size, guiding which drawer boxes in a job will use this unit. One right and one left required per drawer establishes that each drawer using these Tandem runners will rely on a matched pair, forming a consistent hardware standard across a kitchen, bath, or office layout.
The device provides side-to-side adjustment, so once the drawer is hanging on BP563/569 series runners, the installer can nudge the drawer sideways to dial in even gaps across a bank of fronts. Height adjustment of plus 1/8 inch, or 3.0 mm, is built into the mechanism, which allows small vertical changes to bring top edges into a straight line without rebuilding the drawer. Self-adjusting drawer length tolerance helps the system accept small variations in drawer box length, so runners and locking devices can still engage properly when cuts are slightly off. The captive right and self-aligning left device pairing is designed to work together, which supports smooth alignment between the drawer box and the runner system during both installation and later adjustments.

The minimum inside drawer width is 6-11/16 inches, which defines the smallest interior drawer size where this right-hand locking device is intended to function properly.
The synthetic, spring-loaded release levers work with the steel base to lock and release the drawer from the runners, which simplifies removal and reinstallation during adjustments.
This standard locking device with side adjustment is built specifically for BP563/569 series runners, so it aligns with projects based on those Blum systems from the start. One right and one left per drawer define a clear pattern when counting parts for a run of cabinets. Side and height adjustments, together with self-adjusting drawer length tolerance, provide fine-tuning capability after the drawer is mounted on the runners. For drawer interiors at or above the 6-11/16 inch minimum width, this right-hand unit pairs with the left device to secure and adjust the drawer position within the cabinet opening.
