Blum TANDEMBOX M-Height 22" Right Hand Drawer Profile, Gray, 378M5502SAR-WHA

550mm TANDEMBOX Right-Hand Drawer Profile for Gray Cabinet Interiors

This is the right-hand steel drawer side profile from Blum's TANDEMBOX drawer system, in Gray finish, sized at 550mm (22 inches) nominal length. It is one member of the TANDEMBOX side assembly and must be paired with the matching left-hand profile and the appropriate TANDEMBOX runners, back panel, and front fixings to build a complete drawer.

Key Features

• Right-hand orientation — this is the right-hand cabinet member only; the left-hand profile is a separate SKU.
• Gray finish on steel construction — a neutral cabinet-interior color that coordinates with painted and laminate casework without calling attention to the drawer box.
• 550mm (22 inch) nominal length — sized for standard kitchen and bath cabinet depths, pairing with the TANDEMBOX runners and back cut to the same nominal length.
• 100 lb weight capacity — rated for drawers carrying cookware, pantry goods, or other substantial loads.
• Full-extension system — as part of the TANDEMBOX platform, the completed drawer reaches full extension so the entire drawer interior is accessible.
• TANDEMBOX platform component — integrates with TANDEMBOX runners, front fixings, locking devices, and ORGA-LINE organization inserts as one engineered system.

Where This Profile Fits in a TANDEMBOX Build

The TANDEMBOX drawer system is built from matched components: side profiles carry the load and define the box walls, runners provide the travel and motion, front fixings attach and align the drawer front, and a back panel closes the rear. This right-hand profile is the structural wall on the right side of the drawer box as viewed from the front. It slots into the TANDEMBOX runner and locks to the back panel and front fixing hardware. A working drawer requires this right-hand profile, the left-hand profile, runners, a back panel, and front fixings — each a separate order. The Gray finish suits painted kitchen cabinets, frameless European casework with light or neutral interiors, and any application where a low-profile interior color is preferred over the visual weight of a darker or metallic finish.

Steel Build and Gray Finish

The profile is formed steel, finished in Gray — a factory-applied color that runs the length of the profile and presents a consistent, clean face inside the cabinet. Gray reads as a neutral in most cabinet environments: it recedes against white and light-painted interiors and pairs well with Gray or silver hardware accents. The 84mm (3-5/16 inch) profile height gives the drawer side enough depth to carry moderate drawer loads and interface cleanly with TANDEMBOX back panels and front fixings at the same height. For interiors calling for a warmer tone or a metallic look, Blum offers this profile in Inox, Orion Gray Matte, and Stainless Steel — each a separate SKU in the same TANDEMBOX family.

Specifying This Component

Cabinet shops building production runs of frameless kitchen cabinets find the 550mm nominal length well-matched to standard 24-inch-deep cabinet boxes. The Gray finish integrates into builds where the drawer box interior will be visible — open shelving adjacent to drawers, glass-front cabinets, or any layout where the interior view matters. Designers specifying handle-less kitchens can pair this profile with TANDEMBOX's TIP-ON or TIP-ON BLUMOTION systems for push-to-open or combined push-and-soft-close operation; those motion components are part of the TANDEMBOX system and are ordered separately. Contractors and remodelers replacing existing TANDEMBOX drawer sides should confirm the nominal length and height code match the runners already installed before ordering.

The Right Component, Ready to Build

Specify the 550mm TANDEMBOX right-hand profile in Gray when the drawer box interior needs to disappear into a neutral cabinet environment — and when the build calls for the full engineered performance of the Blum TANDEMBOX system.
