Thanks for getting back to us! I'm sorry, but I think you may have weighed the wrong thing. The sash should at least weigh a couple pounds. Are you perhaps measuring the balance itself by mistake?
The sash is the part of the window that actually slides up and down. That is what I need the weight for. Let me know!
Sorry my mistake.
Sash is about 20 pounds
What is the next step for placing a custom order?
Take a look at the S395-21 with the 2040 option. This balance should be a good replacement for your old window balance. Let me know if you have any further questions.
