This is a window balance installed in 1991. It appears that the number 2040 is stamped on the balancer.

I would like to purchase four of these to cover 2 matching windows.

Hello,

It looks like you have either our S351-21, with a 15-002 bottom attachment, or S390-21, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2040 spring strength option for your replacement balances. Thank you!
