Hi - I have a 20 year old Certainteed single-hung window that won't stay open. I've attached a picture of the top and bottom coil springs before and after removal. I've removed all four. The top ones, located halfway up the window track, were screwed in and I pushed the bottom ones up the track to the opening for removal. All of the coils were exposed in the tracks which I notice is not the case on my other similar Certainteed windows. Can you please tell me the replacement parts I will need? Let me know if you need more information.
Thank you,
Steve
