Selecting the Correct Action Parts When Restoring a Vintage Piano

The key factor in selecting correct replacement parts is to insure that the original action dimensions and relationships won't change upon installation. To accomplish this, Renner maintains a century old manufacturing database with master action designs from which it can produce genuine Renner action parts with the same "original dimensions" as were used in the original piano manufacture.

There is only one set of relationships through which the mechanism will operate properly, and you will find those relationships carefully engineered and built into every Renner part. The objective, simply stated, is to protect the authentic design of the piano and to carefully restore it to the original intent of then piano maker.
