How to Reconfigure, Disassemble, Extend and Replace Panels on USM Haller – Refresh Without Replacing

A USM Haller unit is never final. The ball-and-tube system was engineered so you can reconfigure, disassemble, extend and replace individual panels – without replacing the whole unit. That is the real strength of a modular system: you refresh it instead of throwing it away.

Can you reconfigure a USM Haller unit?

Yes – a USM Haller unit can be reconfigured at any time because every joint is reversible and the system is built on a fixed grid. Each node is a 25 mm chrome-plated brass ball with an M8 thread, into which chrome-plated steel tubes screw. You unscrew the tubes, reassemble the nodes and tubes, and move or add panels – turning a low sideboard into a tall shelving unit without buying anything new.

How do you disassemble a USM Haller unit?

You disassemble a USM Haller unit by unscrewing the tubes from the ball nodes and lifting the panels out of their channels – no special tools required. Start at the top and work downward so the structure stays stable. Standard tube lengths are 100, 150, 175, 250, 350, 395, 500, 595 and 750 mm; because every part follows this grid, the pieces fit back together exactly after you take them apart.

Can you replace a single panel?

Yes – you can replace a single panel without touching the rest of the unit. Because panels clip into the tube structure rather than being glued, you release only the affected panel and slot in a new one of the same size. This lets you swap a scratched or off-colour panel, or upgrade an open bay to a door or drawer – part by part.

Can you extend a USM Haller unit with cheaper parts?

Yes – you can extend an existing USM Haller unit with compatible parts that are 60–70% cheaper. Klackjoy supplies balls, tubes, connectors and panels built 1:1 to the USM Haller system and physically compatible with genuine USM Haller (owner-confirmed). You extend, mix or replace parts directly on your existing unit – instead of buying it all over again.

Do I need to replace the whole unit?

No – you do not need to replace the whole unit. The point of a modular system is that you swap or add exactly the part you want to change and keep the rest. A single panel, a few extra tubes and nodes, or one new section is enough to refresh or grow the unit. Every Klackjoy part is covered by a 10-year warranty.

If you want to plan how your reconfigured or extended unit should look, build it in the configurator. For more on the exact fit, read the compatibility guide and the overview of compatible parts.
