This is the Blum TANDEMBOX Boxside Adaptor Set in Gray, a nylon bracket set that connects gallery rails to the TANDEMBOX drawer side profiles. It is designed for installations where the drawer interior and gallery rail assembly need to match Gray TANDEMBOX components throughout.
TANDEMBOX builds have two main situations that call for a boxside adaptor: drawers with gallery railing above the side profile — common in pot drawers, pantry pull-outs, or tall inner drawers — and handle-less fronts where a raised railing carries the visual line of a taller front. In either case, the adaptor brackets are the connection point between the TANDEMBOX side and the gallery rail above it, holding the rail securely and transferring the load back to the drawer structure. This Gray version suits any TANDEMBOX build specified in Gray, keeping the bracket color consistent with the side profile and interior accessories rather than introducing a contrast piece that shows when the drawer is open.
The adaptor set is molded from nylon (polyamide), a material Blum uses throughout its TANDEMBOX accessory program for components that need dimensional accuracy and resistance to repeated loading at a joint. Nylon holds its shape at the connection point without adding noticeable weight to the drawer assembly. The Gray finish is matched to the TANDEMBOX Gray color family, so the brackets blend with Gray side profiles rather than standing out as an afterthought. No secondary finishing or painting is needed on site.
Cabinet shops running TANDEMBOX in Gray across a kitchen or office project will reach for this set whenever a drawer calls for gallery railing. It fits naturally into a standardized pull order: specify the TANDEMBOX sides, the runners, the front fixings, and the gallery rail, then add the boxside adaptor set in the matching color. Designers specifying handle-less cabinetry with raised gallery fronts will find the Gray adaptor keeps the interior as clean as the exterior. Contractors completing a TANDEMBOX installation who are adding or replacing gallery rails on an existing Gray build will also use this set to match existing hardware.
No. This adaptor set is engineered for TANDEMBOX. LEGRABOX and MERIVOBOX use their own system-specific gallery components that are not interchangeable with TANDEMBOX parts.
The source data does not specify handedness for this set. Confirm with the TANDEMBOX planning documentation or a Blum resource whether the adaptor set is symmetric or handed before placing a final order.
Gray and Dust Gray are two distinct TANDEMBOX finish offerings. Match the adaptor set color to the side profile color of your specific TANDEMBOX build — mixing the two finishes will produce a visible mismatch inside the drawer.
No. This set contains the adaptor brackets that connect the gallery rail to the drawer sides. The gallery rail itself is a separate TANDEMBOX component and must be ordered independently to complete the assembly.
Matching the adaptor color to the rest of the TANDEMBOX assembly is a small detail that matters when the drawer is open — Gray bracket against a Gray side profile disappears into the build, while a mismatched color draws the eye. Specify this set alongside your Gray TANDEMBOX sides and runners to keep every visible component on the same color sheet.
