Window Balance Weight

A quick learner from Kentucky says:

32" SERIES 770 BALANCE is the balance I am looking for, However, my existing balance is stamped 3140. It is not stamped with a letter like all the other ones I am seeing in the other questions asked. Which one of these balances would be the equivalent of the one I have?

Hello, thank you for posting!

The 3140 stamp is sometimes seen on older versions of the S770-32. This stamp has been known to transfer over to 32D, which means your window sash weighs between 25 and 30 pounds. I recommend weighing your window sash to confirm!
