Window won't stay open

I see you have spiral balances. If your windows droop, then it may be a simple matter of recharging the balances. Check out the guide below to see how you can do this. You would use our 75-006 tool. If that doesn't work, then the balances will need to be replaced entirely. See our tilt window spiral balance home page and follow the steps to see if anything we carry matches your hardware.

I'm not sure what you mean when you say it's broken in both channels. Could I see a picture of where it's damaged, specifically? If you mean the window jamb, then we will not be able to replace it for you.
