These powder-coated shades stay colorfast for years and can be reordered. The full list of every RAL code is in the colors guide.

What dimensions and sizes does USM Haller come in?

How do you assemble USM Haller?

You assemble USM Haller by screwing the tubes into the 25 mm chrome-plated brass ball nodes (M8 thread) and then fitting the panels into the channels. You work from the bottom up, level by level. For a step-by-step walkthrough, see how to assemble modular furniture.

What tools do you need for USM Haller?
