No markings on this thing anywhere, I currently don't have access to the sash to weigh it either. I'm not sure which model I should be choosing

Hi there!
It looks like you have either our S351, with a 15-002 bottom attachment, or S390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.
Is there a stamp on your metal channel? If not, you'll need to remove and weigh your sash to choose the appropriate spring strength option. There's a chart on the S351 and S390's product page that shows you which option you'll need based on the weight of your sash.
