Spiral balance help

Question

I know I need 30" 3/8' spiral balance but I can't figure out how they hook into the bottom of the window. See pics

I see the clip is attached to the side of the sash. Being a builder's grade window, the sash won't be removable. However, we do have a possible solution.

With someone helping you, you will need to drop the new balance in from the top of the sash, screw it in at the top, then let the spiral drop down. You will then raise the sash and, while someone holds the sash in the open position, spin the spiral up to the bottom of the sash. Finally, with our 75-004 tool, give the balance about three turns to charge it and lock it to the end into the sash clip.

Let me know if you have any more questions.
