Help repairing old windows

Hey Guy. My first thought is that I don't believe the 15-009 is compatible with any other brackets, so you may want to keep that in mind. If you show us pictures of your existing balances and brackets, as well as provide the length and diameter of the balance tubes, that would help us confirm further recommendations. 

Perhaps I can help, Guy. The balances you might need are S500-15 and S500-25. Please check the length of the spiral. The Series 500 spirals are 3/4" longer than the tube. 

In attaching the 17-012 bracket to the bottom of the sash, we first drop the balance tube down from the top on the side of the sash. We screw the balance tube at the top on both sides. Raise the sash and have someone hold it in place. The spiral should have unwound down to the sill. Now take a 17-012 bracket and corral the spiral. That will help in placing the screw holes on the sash. Drill and screw the bracket onto the sash, bring the bow tie at the end of the spiral up to the bracket. Hook the 75-005 tool to the spiral and give the spiral three or four clockwise turns and lock the bow tie to the bracket. Repeat the other side. You might want to screw on some face guides, like 67-002 on the front of the sash to prevent the sash from rocking when operating it.

Let us know if you have further inquiries.
