The sculpture "Klappmeter" was created as part of the project "Blickpunkte" ( „Points of View“) for the "Kulturtage Südliche Weinstrasse 2000" ( „Days of Culture Südliche Weinstrasse 2000“). It was created by the artists Lucie Wegmann and Daniel Moriz Lehr. The artwork shows the interesting landmark of the wine village, because historically, the cradle of the folding metre is in Maikammer. The folding metre with spring lock was invented here in 1886 by the brothers Franz and Anton Ullrich and presented for the first time at the World Exhibition in Paris in 1889. The patent, which made it much easier to measure vertically, was so perfectly developed that it has not needed any improvement anywhere in the world to this day. Today, the so-called "folding rule" or "metre rule" is an everyday utensil for every craftsman and can also be found in almost every German household.
Previously placed in the middle of the vineyards, the folding metre monument has now been given a location in accordance with its significance. It now decorates the newly created roundabout at the southern entrance to Maikammer on the German Wine Route.
