Piano String Cover - Fabric Action Cover

A piano string cover helps protect your piano strings, soundboard, and grand action from dust and dampness. The covers are made of a 100% polyester material. The string covers are designed to be kept on the piano and are perfectly suitable to use while playing. Available in black, red, and burgundy. All covers are custom-manufactured in the United States.

When ordering a soundboard cover, please select from the drop-down menu the size range of your piano (for example, if you have a Steinway Model B measuring 6'11", you would select the size range: "Pianos 6'1" to 8'0"). In the text boxes, type in your piano make and model in the first box, and the exact length of the piano in the second box (when measuring the piano, you want the longest possible measurement, including the piano keys--so you measure from the very front of the keyboard to the tail end of the piano). We have string templates for a number of the most popular pianos--if we do not have one for your specific piano, you can mail us a template and our seamstress can make the cover based on the template. Please note the fabric string covers are custom-made for you upon your order and cannot be returned, so you will want to make sure to measure your piano correctly.

Why Piano String Covers Are Essential in Humid Climates

In humid climates, pianos are vulnerable to moisture-related issues that can affect their performance and longevity. Implementing a piano string cover offers several protective advantages:​

• Moisture Regulation: Excess humidity can cause the piano’s wooden soundboard and action components to swell, leading to tuning instability and mechanical issues. A high-quality string cover acts as a protective layer, reducing the impact of moisture fluctuations and preserving your piano’s internal structure. 
• Rust Prevention: Metal components, including piano strings, tuning pins, and the cast iron plate, are highly susceptible to rust in humid conditions. By placing a string cover over the piano strings, you reduce direct exposure to moisture, preventing oxidation and prolonging the life of your instrument.
  
• Maintain Sound Quality and Performance: Fluctuations in humidity can negatively impact the tonal balance of your piano. A string cover helps stabilize the environment inside your instrument, ensuring consistent sound production and optimal key response over time.
