550mm left-hand longside gallery rail defines the top edge of a Blum TANDEMBOX drawer on the left side, so the side height and containment match the system layout. This rail is identified as Blum, Inc. manufacturer part number 03578522, which ties it directly to the TANDEMBOX drawer construction system for accurate component selection. The 550mm length sets the rail for drawers built around that nominal depth, aligning the gallery rail with corresponding TANDEMBOX components. Its left-hand orientation means it is designed to mount specifically on the left side of the drawer, keeping the system consistent with right-hand counterparts. The gray finish matches the gray Blum TANDEMBOX drawer system appearance, supporting a unified look across the drawer set.
This longside gallery rail is part of the Blum TANDEMBOX Drawer System, so it works within that drawer construction framework on the left side. The 550mm dimension defines where it fits along the drawer length, coordinating with other TANDEMBOX components sized around the same depth. As a top gallery rail on the long side, it completes the upper boundary of the drawer side, giving the drawer its intended side height within the system. Its gray finish matches gray TANDEMBOX components, so the rail visually aligns with the rest of the drawer during installation and final fit-out.
This rail is used on the left side of a Blum TANDEMBOX drawer that is built around a 550mm nominal length, keeping the long side framed to system dimensions. As a longside gallery rail, it runs along the drawer side near the top, so items in the drawer are guided by a defined upper edge. Within the Blum TANDEMBOX Drawer System, this left-hand component partners with system-specific parts on the right side and bottom to complete the drawer structure. The gray finish visually coordinates with other gray TANDEMBOX elements, which helps maintain a consistent appearance across multiple drawers using the same system.
The designation as a longside gallery rail means this part is intended to follow the full usable length of the drawer side, so side height extension is continuous rather than broken into sections.

By aligning to the Blum TANDEMBOX Drawer System, the rail follows the system's geometry and spacing, supporting predictable fit with other TANDEMBOX components matched to 550mm length. The gray finish matters when drawers are specified with gray TANDEMBOX parts, because the rail's color keeps the interior and side structure visually consistent from piece to piece.
