This is the 20 inch (500mm) TANDEMBOX Deluxe cabinet profile in Zinc, a full-extension metal drawer system component from Blum with integrated BLUMOTION soft-close. It is the cabinet-side half of the TANDEMBOX running system, and it pairs with the matching drawer member to complete one drawer's slide mechanism inside a frameless or face-frame cabinet.
The TANDEMBOX system separates the runner into two matched members: the cabinet profile mounts inside the cabinet box, and the drawer member attaches to the drawer sides. This 20 inch cabinet profile is the fixed half — it stays in the cabinet and receives the drawer member when the drawer is loaded. Full extension means the drawer travels its full nominal depth past the cabinet face, so nothing hides behind the front rail. That matters most in base cabinets where pots, tools, or deep bins would otherwise stay out of reach at the back.
The Zinc finish is a practical choice when the cabinet interior calls for something other than white. It reads as a cool, medium-tone metallic that sits quietly behind drawer fronts finished in gray, concrete-look laminate, or natural wood tones without creating sharp contrast. Steel is the underlying material, so the profile is rigid and consistent in section — the Zinc coating does not affect load capacity or motion performance. BLUMOTION is the integrated closing damper Blum builds into the TANDEMBOX runner; it is a true soft-close, not a self-closing ramp, and it adapts to drawer weight automatically.
Cabinet shops specifying a full TANDEMBOX installation in a color palette that calls for Zinc are the primary buyer. The profile is also useful for service and replacement work — when an existing TANDEMBOX drawer in Zinc needs a new cabinet member, this is the part. Designers and homeowners specifying cabinetry who want to coordinate interior hardware color will find Zinc works with a broader palette than white while staying understated. Because this is a single cabinet profile, buyers completing a new drawer need the corresponding drawer member and, depending on cabinet construction, the appropriate rear mounting brackets for face-frame installs.
This is the cabinet profile only — the fixed half of the two-piece TANDEMBOX running system. You also need the matching drawer member that attaches to the drawer box sides to make a working drawer slide.
No. BLUMOTION is a mechanical damper built into the runner mechanism; finish is a surface treatment on the steel profile and does not change closing force, damping behavior, or load capacity.
Yes. TANDEMBOX side profiles mount directly in frameless (32mm grid) cabinets. In face-frame construction, the rear of the profile needs series-specific rear mounting brackets to position it correctly — those brackets are sold separately and must match the TANDEMBOX series.
TANDEMBOX is a metal drawer system — the steel side profiles replace the wood drawer sides entirely. You supply the drawer bottom and back cut to Blum's published dimensions for this nominal length and system height.
Yes. ORGA-LINE is Blum's interior organization line developed for TANDEMBOX drawers. Once the drawer is assembled, ORGA-LINE cutlery trays, utensil inserts, and dividers compose inside the drawer box. Confirm the system height code when selecting ORGA-LINE components, as tray heights vary by drawer side height.
If your cabinet program calls for Zinc hardware inside, this 20 inch full-extension TANDEMBOX cabinet profile with BLUMOTION closes out the color spec and delivers the motion performance the platform is known for — full drawer travel, silent damped close, and 75 lb capacity ready for whatever the drawer carries.
