First Generation Connector Puller for USM Haller: Loosen Stuck Connectors in 3 Steps
Anyone who dismantles old USM Haller furniture knows the problem: first generation connectors cannot be loosened with modern tools. The reason is simple. The first generation connectors have a different geometry than today's second generation connectors. That's why you also need a different tool. We'll show how the special connector puller for the first generation works.
Important First: Which Generation Do You Have?
The two USM Haller connector generations are not compatible with each other. The same applies to the tools:
- The 1st generation connector puller works only with 1st generation connectors
- The 2nd generation connector puller works only with 2nd generation connectors
So before you buy a tool, you should know which connectors are installed in your furniture. In the tutorial on loosening stuck connectors you'll find guidance on distinguishing the generations. Rule of thumb: USM Haller furniture from the 70s and early 80s generally has first generation connectors. Later furniture from the mid-80s onwards and all currently produced furniture works with the second generation.
Here's How the Tool Works in Three Steps
The application is pleasantly simple and requires no prior knowledge:
Step 1: Position the Tool
Insert the connector puller into the tube at the spot where the stuck connector sits. The tool is dimensioned to fit cleanly into the USM Haller tube systems.
Step 2: Push the Tool In
Push the tool into the tube until the inner tube wall touches the outer wall of the connector puller. For particularly stuck connectors, a rubber hammer is recommended to build up more pressure without damaging the surface.
Step 3: Pull the Tool Out
Now simply pull the tool out of the tube. The connector comes out with it. Done.
When Is It Worth Buying?
The first generation connector puller is a specialty tool. It's worthwhile for:
- Collectors and restorers of old USM Haller furniture
- Buyers of used USM Haller furniture from the 70s and early 80s
- Furniture dealers or workshops that frequently work with different USM Haller generations
- Anyone who wants to expand their USM Haller collection with older pieces
If you only own current USM Haller furniture, you don't need this tool. In that case, the second generation connector puller is the right tool. Anyone who has both old and new furniture, however, cannot avoid both tools. Combined with the Professional Tool Sets or the 15-piece complete set in a case, you get a very complete equipment package that truly covers every USM Haller generation.
Practical Tips from the Workshop
A few hints that make life easier in practice:
- Check the generation first: Never work with the wrong tool. It won't work and can in the worst case damage the connector or tool. With mixed inventories, it's worthwhile to keep both tool generations on hand
- Keep a rubber hammer ready: For really stuck connectors, pure hand force often isn't enough. A rubber hammer distributes pressure evenly and protects the furniture surface
- Consider corrosion: Old connectors can develop corrosion through moisture or storage conditions, which makes loosening more difficult. Patience helps more than brute force
- Check the connectors: After loosening, take a look at the connector. Better to replace damaged ones with matching spare parts
Where to Buy?
The tool is available from our recommended partner Limics24. Shipping comes from the German warehouse, typically within a few business days. Limics24 specializes in USM Haller compatible spare parts and tools and stocks both the first generation connector puller and the matching tool for the second generation.
Our Verdict
The first generation connector puller is a niche tool, but absolutely indispensable for the right target group. Anyone working with old USM Haller furniture from the 1st generation cannot proceed without the matching specialty tool. Modern tools simply don't work here because the geometry of the old connectors is different. The application is straightforward, and the result all the more satisfying when stuck connectors finally come loose after decades.
