Description
Balance Block for 5/8″ Spiral Balance Rod
This balance block, also known as a pivot lock balance shoe, is designed specifically for tilt-in windows that use a 5/8″ (15.9mm) tilt spiral balance rod. It serves as a key component in the window sash support and pivot system, ensuring smooth tilting and secure locking during window operation. The open cam design allows for proper engagement and performance, while the cam is made of durable zinc for long-lasting function.
The pad is available in white or gray, allowing for some flexibility to match existing hardware aesthetics or window frame coloring. This part is intended for use with compatible tilt-in windows that require a balance shoe/lock block with these specific dimensions. By replacing worn or broken balance shoes, you can restore proper window tilt functionality and security without replacing the entire window balance system.
