Replace window balance

Quick Learner from San Jose CA

I need to replace the balances for 2 wimdows. The length is 21 inches. I weighed the window sash

It's 21.5 lbs.

Could you let me know the correct part number and can I order it from you?

Hey there!

I recommend our S380-21 or S385-21 channel balances with the 2040 option. I know they look almost identical at first glance but note the difference in the bottom shoe depth. You'll have to measure as shown below to see which Series is best for your repair.
