This is the 22 inch (550mm) full-extension cabinet member for Blum's TANDEMBOX drawer system, sold as a matched left-hand and right-hand pair. It mounts to the cabinet interior and forms the fixed half of the TANDEMBOX running gear, working in tandem with the drawer member to deliver full extension with integrated BLUMOTION soft-close.
In a TANDEMBOX installation the cabinet member is the component that stays with the cabinet — it attaches to the cabinet side wall or bottom and carries the running track that the drawer member rides on. Pairing this 22 inch cabinet member with the correct TANDEMBOX drawer member and front fixing bracket gives you the full running assembly. Because it is the BLUMOTION variant, the damping mechanism is housed here in the cabinet member, engaging automatically as the drawer closes. This profile suits face-frame and frameless cabinet construction; in face-frame applications, confirm rear mounting bracket compatibility for this nominal length, as rear brackets for TANDEMBOX are series-specific and sold separately.
The profile is formed from steel and finished in Zinc, a neutral metallic tone that coordinates with the standard TANDEMBOX component palette. Steel construction keeps the profile rigid under load across the full 22 inch span, and the zinc finish resists the surface wear that comes with repeated drawer cycles in a busy kitchen or shop installation. This is an indoor cabinet component — it is not rated for exterior or high-moisture environments.
Cabinet shops building TANDEMBOX-equipped boxes to a 22 inch depth will order this cabinet member whenever they need to replace or extend a BLUMOTION soft-close installation, or when sourcing components separately rather than in complete drawer sets. Designers and contractors specifying handle-less kitchens with TANDEMBOX often need individual cabinet members to complete a run when set quantities do not match drawer counts exactly. Homeowners replacing a damaged cabinet member in an existing TANDEMBOX installation will find this the direct replacement for the 22 inch BLUMOTION zinc variant.
This is the cabinet member only — the half that mounts inside the cabinet. You need the corresponding TANDEMBOX drawer member to complete the running assembly for one drawer.
The listing covers both orientations — one left-hand and one right-hand cabinet member — so one order gives you both sides for a single drawer.
TANDEMBOX cabinet members can be used in face-frame builds, but face-frame installations typically require rear mounting brackets specific to the TANDEMBOX series and nominal length. Those brackets are sold separately.
No. TANDEMBOX cabinet members are engineered to work with TANDEMBOX drawer members and system components. They are not interchangeable with other brands' drawer systems or generic drawer boxes.
BLUMOTION is Blum's name for their integrated damping system — it is a soft-close mechanism. It slows and silences the drawer over the final inches of closing travel. It is not a self-closing ramp; the drawer needs to be pushed to near-closed before BLUMOTION takes over.
Pair this 22 inch BLUMOTION cabinet member with its TANDEMBOX drawer member counterpart and the appropriate front fixing, and the cabinet side of your soft-close drawer installation is complete.
