Tandembox left-hand longside gallery rail defines the upper side of a deep drawer in a Blum TANDEMBOX drawer system, so the tall drawer side stays aligned and supported throughout its travel. The part is specified for the left side of the drawer, which helps keep the system consistent with Blum TANDEMBOX hardware layouts on jobs where orientation matters. The 400mm length serves deep drawer applications of that nominal depth, tying the rail directly to the intended cabinet and drawer sizing. The rail is described as white aluminum, which identifies both the material and appearance so the visible side component matches other white aluminum elements in a TANDEMBOX installation. As part of the Blum TANDEMBOX Drawer System product class, this longside rail works within that specific drawer construction system, helping installers maintain the same hardware family across a run of cabinetry.
The left-hand designation of this Blum, Inc. gallery rail assigns it to the left side of a TANDEMBOX deep drawer, clarifying orientation when laying out drawer components on a bench. Being a longside gallery rail, it runs along the upper side of the drawer rather than across the front, which supports the tall drawer side along its length within the TANDEMBOX construction. The 400mm reference ties the rail to deep drawers of that nominal depth so rail choice can follow the same measurement used for drawer box planning. Because the part is identified as white aluminum, both the appearance and base material are defined, which helps the rail blend with other white aluminum Blum TANDEMBOX pieces in a project.
This Blum TANDEMBOX left-hand longside gallery rail is described specifically for deep drawers, placing it on applications where the drawer side extends higher than a standard drawer box. Its role as a longside gallery rail means it spans along the upper side of the drawer, so the tall sidewall has a defined top edge within the TANDEMBOX configuration. The 400mm length directs it toward drawer boxes built around that depth, which connects directly to carcass and slide planning in a Blum TANDEMBOX drawer system layout. Because the part is designated left-hand, it is intended for the left side of the deep drawer, separating it from any right-hand components in the same system and giving installers a clear assignment when organizing parts by side. Being part of the Blum TANDEMBOX Drawer System, this gallery rail operates in that named construction system rather than as a generic drawer part, keeping brand, system, and function aligned for repeatable installations.
The identified white aluminum material and finish on this longside gallery rail help the visible side component match other white aluminum TANDEMBOX parts, which keeps deep drawer sides visually consistent across a project that specifies this appearance. The explicit 400mm length connects the rail to a defined deep drawer depth, so once a plan calls for 400mm TANDEMBOX drawers, the rail choice follows the same measurement and supports predictable hardware selection. The left-hand orientation detail reduces confusion when drawers use handed components, because this part number, 04405731, is tied to the left side in Blum TANDEMBOX deep drawer work. As a gallery rail for deep drawers within the Blum TANDEMBOX Drawer System product class, it carries a role tailored to that system, so installers working within TANDEMBOX can rely on this part as the longside rail element for the left side of a 400mm deep application.
