A detailed comparison of two leading drawer systems: Blum Tandembox Antaro / LEGRABOX and Hettich InnoTech Atira / ArciTech — construction, load capacity, looks, and price.
Blum Tandembox
Austrian Blum's drawer system. Two lines: Antaro (steel sides) and Intivo (steel with inserts). Above that — LEGRABOX with slim aluminium sides.
- Full extension: 100% travel included as standard
- Blumotion built in — smooth soft-close and quiet opening in the base product
- Load capacity: Antaro up to 40 kg, LEGRABOX up to 70 kg
- Sides: painted steel (Antaro) or aluminium (LEGRABOX)
- Side heights: M (86 mm), C (111 mm) — matched to different door heights
- Synchronised running built in — drawer won't rack or skew
- TIP-ON optionally — push-to-open without a handle
Hettich InnoTech Atira
The German answer to Tandembox. Base line — InnoTech Atira; premium — ArciTech with wider sides and a richer built-in organiser system.
- Full extension: 100% travel standard
- SilentSystem integrated soft-close — equivalent to Blumotion
- Load capacity: InnoTech Atira up to 40 kg, ArciTech up to 50 kg
- Sides: aluminium or steel depending on the series
- Side heights: equivalent options to match different door heights
- SoftSys synchronisation — no racking
- Push-to-open optionally — for handleless facades

What actually differs in practice
- Motion quality — identical. You can't tell the difference blindfolded
- LEGRABOX is slimmer and lighter than InnoTech Atira — matters if the inside of the sides is visible
- Blum leads on maximum load: 70 kg (LEGRABOX) vs 50 kg (ArciTech)
- Hettich ArciTech comes with a richer inner divider system as standard
- Blum spare parts and buffers are easier to source on the market
- Hettich is 10–15% cheaper for an equivalent configuration
Choosing between Tandembox and InnoTech is primarily the furniture manufacturer's decision, not the buyer's. Ask which system your manufacturer works with — no one will retrain their installer for a single order.
When it makes sense to specify a brand
- LEGRABOX — if you want the slimmest sides and need over 50 kg load capacity
- ArciTech — if built-in inner dividers matter without extra cost
- Everything else — go with whatever your manufacturer installs: the result will be the same
