TANDEMBOX ECO top for W400mm Cabinet - Orion grey matt
This is Blum's integrated waste solution for a 400mm wide cabinet, designed to make the most of limited space while keeping your kitchen organised and odour-free. The system combines two bins with a total capacity of 46.2 litres in a pull-out drawer format.
Where It Fits
This unit fits into a standard 400mm wide base cabinet with a minimum internal height of 630mm. It's particularly useful in galley kitchens or smaller spaces where you need efficient waste storage without sacrificing valuable cabinet real estate. The system works well next to your sink or prep area for easy disposal while cooking.
How It Works
The waste bins sit in a pre-assembled frame that pulls out on heavy-duty runners rated for 30kg. You get one larger 42-litre bin for general waste and a smaller 4.2-litre compartment for recycling or food waste. The drawer operates with Blum's BLUMOTION soft-close technology, so it closes silently even when loaded. An odour trap shelf sits across the top of both bins to prevent smells escaping, and it doubles as storage for bin bags.
Why It Matters
Having your bins hidden but easily accessible changes how you work in the kitchen. There's no need to open cupboard doors with messy hands or struggle with bins that tip over when you pull them out. The odour control means you can keep the cabinet door closed without worrying about smells, and the soft-close mechanism handles the weight of full bins without slamming.
Design Consideration
This system maximises the usable space in a 400mm cabinet better than traditional pull-out bins that leave gaps around the edges. However, you do need adequate depth, a minimum of 503mm internal cabinet depth is required. The system works with most door styles, including shaker doors, thanks to wide fixing points. If you frequently have very heavy waste loads, the reinforced glass fibre handles and stability brackets provide the strength needed.
Build Quality
The frame comes pre-assembled around Blum's Ninka system with stabilising brackets for additional strength. The runners are rated for 30kg capacity and include BLUMOTION soft-close as standard. The bins themselves are robust enough to handle daily use, and the odour trap shelf is designed to sit securely across the full width of both containers.
Options
This model comes in Orion grey matt finish and is specifically sized for 400mm cabinets. Optional extras include hands-free electronic opening activated by foot movement, which can be retrofitted later, and integrated LED lighting that can be dimmed or switched off. Additional lids are available if you want extra odour control for specific waste types.
Consider this system if you want to maximise waste storage in a compact space while maintaining easy access and odour control. The soft-close operation and thoughtful details make daily kitchen tasks smoother, though you'll need to ensure your cabinet has sufficient depth and height clearance.
