This is the left-hand steel drawer side profile from Blum's TANDEMBOX drawer system, 400mm (16 inch) nominal length, finished in Gray. It is a structural component of the TANDEMBOX platform — the left side profile that houses the integrated runner and forms one wall of the drawer box. Order this alongside its matching right-hand profile and the system's back panel and front fixings to build a complete TANDEMBOX drawer.
The TANDEMBOX system replaces wood drawer sides with formed steel profiles that carry the runners as part of the wall itself. This left-hand profile is the structural backbone of the drawer's left side: the runner is built into the profile, so there is no separate slide to mount or align. The 400mm nominal length governs which cabinet depth the drawer suits and which TANDEMBOX back panel and front fixings pair with it. In a typical build, this profile, its right-hand counterpart, the matching back, and the front fixing brackets arrive as a set or are ordered together as a matched group — all at the same 400mm nominal length.
The 84mm side height positions this profile in the standard range of TANDEMBOX side heights. It suits everyday kitchen drawers — cutlery, utensil, and light storage pulls — and works with ORGA-LINE interior organization trays designed for TANDEMBOX. For taller drawers or deeper pot-and-pan pulls, TANDEMBOX offers taller side profiles; for a lower-profile cutlery drawer, shorter sides are available.
Gray is a practical interior finish for TANDEMBOX builds in kitchens with painted white or light-tone cabinet boxes, laminate interiors, or installations where the drawer interior will be visible when open. It is a neutral that reads as clean and intentional without drawing attention. For builds where the interior color is a design specification — matching inset fronts in Orion Gray or Stainless Steel LEGRABOX-adjacent palettes — Blum offers the TANDEMBOX profile family in additional finishes. Gray suits the installer who needs a finished, professional-looking interior in a production or renovation context where color coordination starts with the cabinet box rather than a premium drawer system palette.
Cabinet shops building kitchen and bath projects on the TANDEMBOX platform order profiles like this one when expanding into a new drawer length, replacing a damaged side on an existing installation, or stocking ahead of a production run. Designers specifying handle-less or high-usage drawers reach for TANDEMBOX profiles because the steel construction tolerates daily use in demanding kitchen environments better than a wood drawer box at the same price point. Contractors completing a renovation order individual profiles to match what was already installed — this SKU's left-hand orientation and 400mm nominal length are the two attributes that must match the existing system exactly.
This is one left-hand side profile only. To build a working drawer, you also need the matching right-hand profile, a back panel, front fixing brackets, and a drawer front — all at the same 400mm nominal length and 84mm side height for the TANDEMBOX system.
The integrated runner is built into the profile body, and that geometry is handed. The left-hand profile mounts on the cabinet's left side; the right-hand profile mounts on the right. Ordering two of this profile gives you two left-hand sides — an unusable pairing.
No. TANDEMBOX components — profiles, back panels, front fixings, and locking devices — are engineered for the TANDEMBOX system and do not interchange with LEGRABOX, METABOX, or other Blum drawer platforms.
Yes. ORGA-LINE is Blum's interior organization line built for TANDEMBOX drawers. Tray combinations are composed to fit the drawer's interior width at the 400mm nominal length.
The closing mechanism depends on the TANDEMBOX runner specified for the system, not the side profile itself. The profile is compatible with TANDEMBOX runners including BLUMOTION soft-close versions — confirm the runner spec when ordering the complete system.
A TANDEMBOX drawer comes together only when every component matches — nominal length, side height, and handedness. Confirm the 400mm length and left-hand orientation against your cabinet spec, then add the right-hand profile and system components to complete the build.
