General Aluminum non-tilt window spiral balance

This kind of sash isn't made to be removable, unfortunately. 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.

Yep, it should be a kind of bracket or tab. You can see all the different types we have here to get an idea of what it may look like.
