You could try charging your balances first, to see if you can give them some of their tension back. You can use our 75-006 tool. If you don't feel tension build after about three turns, then you probably need new balances. Since these are tilt windows, the spiral balances will be either our Series 900 (3/8" diameter tube) or Series 600 (5/8" diameter tube). I'm not sure if you also needed that pivot shoe. It looks to be in good condition. If you did want a new one, though, then I'll need a photo of it out of the window. I'll also need to know its width and thickness. Let me know if you had any questions. |

Hello again! Thank you for your kind words. We certainly try our best. Your shoe looks like a good match for our 15-045, which just so happens to be a common pairing with our Series 900. I think this is a good choice for your project. As for the balance tip color, since yours doesn't have one you'll need to weigh your sash on a scale to know which one to go with. We have a chart on the S900-29 store page that tells you exactly how much weight each option supports. |
