Bathroom Window Side-Mounted Balance

Thanks for reaching out to us. I recommend the S380-14 or S385-14 channel balances. The best match will depend on the depth of the bottom fitting so you'll have to measure as shown below. Based on your old 13-3 stamp, you'll want to select the 1330 stamp option as well. 

I'll be here if you have any questions!

You got it, David! I'm very happy I could help. Good luck with the repair; I'll be here if you need anything else!
