Window balance replacement

Hello, I need to replace window balances in a couple of windows. They're about 20 years old. The spring is just under 1/2" and stamped Caldwell 5#-35" EX.

Do you sell these or have a replacement balance?

Thanks, Ken

Yes, I think these are the parts I need. To clarify, there is a spring in each housing, so I need two springs per side? I'm also having trouble figuring out how to get the existing housings out of the window frame. Any suggestions?

Thank you very much.

From Bloomington happens to have the same Tandem Coil system I have and what a nightmare.

Of course there are no cut outs in the jam, I figure I'd make one just big enough to take the top half case off, but small enough for the cover to fit back over without a big hole in the jam. I then pulled out the bottom half. Of course I then realized you could not put the tandem case back in the same way, because the coils have to be pulled together and attached first to the mounting bracket, so I ordered the jam spreaders.

I wonder will the spreaders pull the jam out far enough to fit the whole tandem case with room to attach the coils to the mounting bracket without cracking the vinyl? There doesn't look like enough space to work with attaching the coils to the bracket while the bracket is attached to the jam, so I have this idea of taking the bracket off and and attaching the coil, but the bracket has no stable position on the case to hold on too, without the coil snapping back.

The video you mention in the post is a single coil which looks very simple. I could not find a demo like that on the tandem coil. Is there one? Could you do one? :)

Thanks very much,

Paul

Thanks Tom, haven't tackled it yet and just received the jam spreaders(THANK YOU!) I can't wait to try them out!
