2400 balance

Hello, thank you for posting,

Please review the style of the Series 775 channel balance as a replacement. You will need to measure the length of the metal channel only to determine the correct length and measure the width of the balance shoe. The shoe should measure either 1" or 1-1/4" wide.

The 2400 stamp does not directly translate to our options. You will need to obtain the weight of the window sash and compare to the strength chart under the product description of the corresponding length. 

Please review and let us know if you have any additional questions!
