This is the 450mm left-hand longside top gallery rail from Blum's TANDEMBOX drawer system, finished in Gray. It mounts along the top edge of the left-hand TANDEMBOX drawer side to raise the effective side height, retain taller contents, or support a taller drawer front on a low-profile box.
A gallery rail above the drawer side serves two purposes: it raises the practical wall height so taller contents stay contained, and it gives a taller drawer front more surface area to attach to without requiring a taller side profile on the whole box. This rail is the longside version, meaning it runs the full length of the drawer rather than across the back. In a TANDEMBOX drawer configured for pots, pantry pull-outs, or tall utensil storage, the top gallery rail keeps items from tipping toward the sides while the drawer travels. For a drawer front that stands above the box, the rail provides the additional bearing surface the front fixing needs.
The Gray finish is the standard color for TANDEMBOX drawer systems specified in Gray. Blum's platform approach means every component in the system — side profiles, back panels, front fixings, and gallery rails — is offered in the same finish families, so a Gray gallery rail integrates without a visible mismatch. For drawers built in Silk White, Stainless Steel, or other TANDEMBOX finish options, select the rail in the matching color. Components across finish families are not typically mixed in a finished installation.
Cabinet shops specifying TANDEMBOX drawers for kitchen pull-outs and pantry cabinets order top gallery rails when the drawer content or front height calls for a taller effective wall. Designers working on handle-less kitchens with tall slab fronts sometimes need the additional fixing surface a gallery rail provides above the standard side height. Contractors replacing or completing a partial TANDEMBOX installation order this rail when a gallery rail was specified in the original build but not delivered. Because the rail is handed, left-hand and right-hand versions are both required to complete one drawer — confirm which side is needed before ordering.
Only TANDEMBOX. Gallery rails, side profiles, front fixings, and other TANDEMBOX components are engineered to the platform and will not fit Blum's LEGRABOX, MERIVOBOX, or other drawer systems, or any other brand's runners.
No. This is the left-hand rail only. To complete one drawer you need one left-hand and one right-hand rail at the same nominal length and finish. Order the corresponding right-hand rail separately.
The 450mm nominal length is the primary fit dimension — the rail is designed for drawers at that nominal length. Side height compatibility is specific to the TANDEMBOX configuration; confirm the rail suits your side height against the TANDEMBOX system documentation or your Blum representative before ordering.
No. The gallery rail raises the effective wall height for content retention and front support — it does not change the drawer's structural load rating, which is set by the runner and side profile.
A Gray top gallery rail matched to your TANDEMBOX nominal length and side specification means the drawer finishes with consistent color, correct geometry, and content retained where it belongs — no visible gaps, no mismatched components, and no return trip to source a missing part.
