The Change of Generations

Around 1990, the time had come: the 1st generation of the USM Haller design classic was replaced by the 2nd generation of the system furniture. This transition introduced several changes, including new components, elements, and functional updates. Reason enough to take a closer look at both generations.

If you place the two generations side by side, the difference isn’t immediately visible. As so often, the devil is in the details: the biggest issues – especially during a redesign or disassembly – will come from the connectors. While the outer components of both USM Haller generations present no challenges during setup or removal, the connectors of the 1st generation have been replaced in the 2nd generation with a different, more user-friendly design.

Connector – 1st Generation

Consists of three elements:
1× screw, 2× external clamps or threads.

Disassembly: Only possible using a 1st generation connector puller.

Connector – 2nd Generation

Consists of two elements:
1× screw with plastic sleeve, 1× external thread.

Assembly and disassembly: Possible with a 2nd generation tool set.

Once you know which generation your furniture belongs to, things get much easier! There is a specific tool set for each generation that allows you to assemble, disassemble, or modify your system furniture as needed.

If you are still unsure, we recommend the Rudi tool set, which is compatible with both generations.

Conclusion

While the differences between the two generations are relatively minor and don’t justify calling it a completely new system, there are clear differences in handling and disassembly.

Overall, disassembling 1st generation USM Haller furniture is a bit more complex. However, from a visual standpoint, the differences are barely noticeable – even to a design expert. In the end, it all comes down to personal preference and experience.
