Block and Tackle rod Inquiry

Hello, thank you for posting,

You have an older rod balance that is no longer made, but we recommend reviewing the Series 770 channel balance as a possible replacement. You will need to measure the length of the balance to determine the correct length and obtain the weight of the window sash. Compare the sash weight to the strength chart on the corresponding length product page to choose the correct spring stamp option. 

Please let us know if you have any additional questions!
