New pivot shoes and support piece

Question

Hi, I'm in need of buying two replacement shoes for a few of my windows.  But I don't know which one to buy.  Can you help me in finding out what size this is?

Hello, thank you for posting,

Your balance assembly resembles the 15-180 pivot shoe that is compatible with the Series 190 coil springs. Please review the overall dimensions to confirm a good fit! Let us know what you think and if you have any additional questions.
