Windows are just over 20 years old

Possibly an American brand window

Hello,

We can't be sure with your pivot shoe still installed but what I can make our reminds me of the 15-178 or 15-188. You'll need to remove the shoe from the window jamb to compare the width and thickness to yours.

Dimensions for 15-178

As for the balance, the S770 uses the same type of terminal clip at the end of the pulley but you'll need to confirm that the rest of the specifications match the information from our product page. There should also be a stamp on the metal channel that would correspond to one of our strength options. Thank you!
