This is the left-hand longside top gallery rail for Blum's TANDEMBOX drawer system, finished in Gray and sized at 400mm (16 inches). It mounts along the top of the left drawer side to increase the effective side height, retain taller contents, and support a taller front on a lower-profile TANDEMBOX box.
A top gallery rail extends the functional height of a TANDEMBOX drawer box without moving to a taller side profile. That makes it the right choice for pot drawers, pantry pull-outs, and deep storage applications where contents are tall enough to tip or shift during use. It also lets a taller drawer front sit flush above a lower-profile side, which is a common design move in handle-less kitchen layouts. The Gray finish is the match for Gray TANDEMBOX interiors — if your box sides are White or a different finish, select the rail in the corresponding color.
The rail is finished in Gray to coordinate with Gray TANDEMBOX side profiles. Because TANDEMBOX components are color-matched at the factory, mixing finishes within one drawer produces a visible mismatch at the top edge where the rail meets the side. The construction material is not stated in the source data for this SKU. This rail is engineered for the TANDEMBOX platform; LEGRABOX and MERIVOBOX use their own gallery rail programs and are not interchangeable with TANDEMBOX parts.
Cabinet shops running TANDEMBOX in Gray reach for this part when they are building deep drawers for pots, pantry goods, or tall workshop storage. Designers specifying handle-less kitchens use the gallery rail to raise the apparent front height above a low-profile box. Because it is a left-hand component, it pairs with the matching right-hand rail — order both to complete one drawer. A 400mm nominal length means the cabinet depth and the other 400mm TANDEMBOX components already on the job all align without modification.
This is the left-hand rail only. A right-hand rail is a separate part — order one of each to equip one drawer.
No. Gallery rails are engineered per platform. This part fits TANDEMBOX side profiles only; LEGRABOX and MERIVOBOX have their own rail accessories.
Technically the rail may attach, but the color will not match. TANDEMBOX components are finish-matched; use Gray rails with Gray sides and White rails with White sides.
The gallery rail retains contents and supports a taller front at the top edge of the box, but it is not a load-bearing side wall. It raises the effective height for content retention and front sizing, not for structural capacity.
The rail attaches to the TANDEMBOX side profile; attachment hardware requirements are system-specific. Confirm with the TANDEMBOX installation documentation for your box configuration.
Pairing this Gray gallery rail with a Gray TANDEMBOX box delivers a finished drawer interior that looks intentional from front to back — no mismatched trim, no afterthought extensions. Order the matching right-hand rail alongside this one and the deep drawer is ready to work.
