About this item:

  • BACKRAIL CLOTH FUNCTION: When the front of the key goes up and the back of the key goes down, this cloth is designed to quiet the sound of the key returning.
  • GLUING PROCESS: Glue under the front edge of the cloth but not under the back edge (where the key comes down on the felt) for the best results. This produces a softer sound and allows you to shim under the felt as needed.
  • KEY CLOTH THICKNESS MEASUREMENT: The thickness of the backrail cloth is usually compressed due to age, especially if it is very old and has been used a lot. Try to measure the thickness of the cloth on a part that is not as worn. This will generally show the original thickness of the cloth.
  • AVAILABLE IN DIFFERENT THICKNESSES: This backrail cloth is available in 5 different thicknesses for you to choose from:

          * .235" Thick
          * .215" Thick
          * .185" Thick
          * .165" Thick
          * .145" Thick

  • HIGH QUALITY FELT: Made from finest quality cloth.
