General Aluminum Spiral Balance





Your windows are builder-grade, which means that your sashes are not removable. The first thing you'll need to do is straighten out the 17-052 bracket so that you can reach the bow tie at the end of the Series 400 window balance using the 75-005 tool. You might be able to use needle nose pliers to straighten out the sash bracket. Next, unscrew the balance tube at the top of the window track. After you straighten out the bracket, hold the sash open. and use the 75-005 tool to hook onto the balance spiral and release it from the bracket. From there, you should be able to manipulate the balance out of the bottom of the window sash.




Looking at your photo, the bottom part of the bracket is bent upwards. It needs to be bent down like the 17-052 product image. You might be able to do it with needle nose pliers since I don't believe you can remove the sash in this type of window to access the hardware.
