Window part assistance

This is called a coil balance. It looks like you need new springs and a new cover. We can help, but I will also need to see a picture of the pivot shoe; this is a square or rectangular piece of plastic that the spring screw to; it should be below what you're showing me now. Please also tell me how thick the spring is.

Perfect, thank you! Since your spring is 3/8" thick, and based on the style of the shoe you have here, I recommend the Series 165. You will need the stamp printed on the old spring to choose the best option.

I also recommend the 15-204 cover. This is designed to hold two Series 165 springs.

Thank you! You're very kind to say so. Please let me know if you ever had any other questions. We're always here to help.
