This is the left-hand cabinet profile for Blum's TANDEMBOX drawer system, 550mm (22 inch) nominal length, zinc-plated steel with integrated BLUMOTION soft-close. It is the cabinet-mounted member of a TANDEMBOX runner pair — the fixed side that stays in the cabinet while the drawer rides on it.
A TANDEMBOX drawer needs two cabinet profiles — one left, one right — mounted in the cabinet box at the correct height for the chosen side height. This is the left-hand profile. In production cabinet work, confirming handedness before ordering prevents the most common assembly delay in TANDEMBOX builds: arriving at installation with two profiles from the same side. The 550mm nominal length suits standard base and tall cabinet drawer openings with a cabinet depth of roughly 600mm; check the Blum installation spec for the exact cabinet depth requirement at this nominal length.
BLUMOTION is integrated directly into this cabinet member, which means the soft-close function is already present when the profile is installed — no clip-on damper to lose or forget. The drawer member rides the profile, and the closing sequence engages automatically over the last portion of drawer travel regardless of how the drawer is pushed closed.
The profile is formed steel with a zinc plating that gives it a neutral, metallic appearance inside the cabinet and protects the base metal from light moisture typical of enclosed cabinet interiors. Zinc is the standard finish for the TANDEMBOX cabinet profile line and coordinates with TANDEMBOX zinc drawer sides if both sides of the box are ordered in matching finish. The BLUMOTION mechanism is factory-installed; it is not a field-serviceable add-on, which means consistent damping performance from the first drawer to the last in a production run.
Cabinet shops running TANDEMBOX on kitchen, bath, or casework projects order cabinet profiles as individual components when building their own drawer boxes to spec. This left-hand profile is also the correct replacement part when a single member in an existing TANDEMBOX installation needs to be swapped — confirming the nominal length and handedness against the installed hardware before reordering. Designers specifying handleless kitchens sometimes source TANDEMBOX components separately to pair with TIP-ON or TIP-ON BLUMOTION units ordered alongside; confirm that the opening system components are matched to the TANDEMBOX series before combining.
The drawer member is a separate component. This is the cabinet profile only — the piece that mounts to the cabinet box. You need a matching drawer member to complete a working runner on this side.
No. TANDEMBOX cabinet profiles are specific to the TANDEMBOX drawer system. TANDEM and MOVENTO are separate Blum runner families with their own components; they do not share profiles, drawer members, or front fixings with TANDEMBOX.
BLUMOTION is integrated into this cabinet profile at the factory. There is no separate damper unit to clip on or adjust; the soft-close function is active as soon as the profile is installed in the cabinet.
Blum publishes the exact cabinet depth requirement for each nominal length in the TANDEMBOX installation guide. Check that specification against your cabinet depth before ordering; the nominal length and cabinet depth are not the same number.
One per drawer — this is the left-hand profile only. Each drawer requires one left-hand cabinet profile and one right-hand cabinet profile, plus the corresponding drawer members on both sides.
In any TANDEMBOX build, handedness is the detail that determines whether components arrive ready to install or sit on a shelf waiting for a replacement order. Confirm left versus right, match the nominal length across every component in the drawer set, and the BLUMOTION close takes care of itself from there.
