Piano Felts: Balance Rail Punchings


Our top-quality piano felts include balance pin punchings in a few varieties. It is important to have a firm support for the key pivot point at the balance rail. A thick or spongy felt punching will compress under a strong blow, robbing energy from the system which reduces the tonal output of the piano. When choosing a regular type of felt punching, make sure it is very thin, such as our thin red punchings cut from bushing cloth.

Better yet, use our firm Crescendo™ Felt balance punchings.  The regular thickness is 1.4mm /.056″, a thick version of 2.2mm/.090 is also available.  The Accelerated version with one side cut off can reduce downweight by up to a several grams.
