Products for Professional Piano Technicians

Grand Wippens

Our wippens feature precision machined regulating screws and graduated spring tension for optimum regulation. On fine quality pianos this amazing action mechanism, perfected over a period of 300 years, is made from all natural living materials like fine woods, felt, and leather which depend on small action centers to precisely control their motion. These specific tolerances must also move naturally with the environment.


Some of our wippen designs include this feature designed for superior fine adjustments after initial rough regulations. Also prevents butterfly spring from wearing a noisy groove in the repetition lever.

The HIGH DEFINITION FLANGE we invented over 30 years ago provides a more accurate flange seating on the many different rails produced over the years for both vintage & modern pianos, creating stability in the action and a more accurate transmission of power from key to string.

One of the advantages of the action parts offered by Lloyd Meyer & Company, LLC and Renner USA is the use of a special wood called Weissbuche, or Hornbeam in English, which is naturally air-dried and aged to provide stability over many years.

Our superior wippen designs, made exclusively in Germany from the finest quality materials, are among the reasons our products are preferred by the world's finest quality piano makers and rebuilders.
