Hi, when the window opens, and I try to hold it, it won't stop, just sliding down. I am trying to replace it. Is it only to fix this issue, by the way?

I need the spring assembly. I need 1 set of 2 please. I also need the 2 cover pieces thank you

Hi, I have to windows that will not stay up. The coil springs are broken on both sides and I'm looking for replacements. One shoe is also broken, but I'd prefer to replace them all. I can't see any stamps on the coils, but the window sash weighs 23 lbs. These are builder grade windows. Thanks. ... (cont.)
