35 inch tilt window block and tackle sash

Quick Learner from Philadelphia PA
I am trying to locate 2 replacements for my 22 year old windows.
The windows themselves say Thermolite Inc 1GCC CBA02 on them.

Can someone help me locate them please or do you have them ?

Hello, thank you for posting,

Your balance resembles the Series 770 that installs using a screw at the top. Please review the overall style to confirm a good fit! You will need to look at the metal channel for a number that will indicate the spring strength stamp option needed to support the window sash.

Let us know if you have any additional questions.
