Hi.
I have 19 windows where I have to replace Milgard window balance springs. Milgard models #19 3 BSI TT (actual 20 1/2"); #25 4 BSI TT (actual 26 1/2"); and #13 4 BSI TT (actual 14 1/2"). I have measured from the very top to very bottom including plastic ends.
I have noticed that the small clip in photo #2 seems to fall into the frame slot photo #1 You can see the clip installed but it is just long enough not to fall in; but they will soon work themselves into the frame and then slip out and retract; no longer holding the window.)
Perhaps you have another clip arrangement that will hold better.
My totals are: 12 each of Model 25 4; 8 each of Model 13 4; and 18 each of Model 19 3.
I would like to get initially two of any of the about sizes to ensure they will properly work if possible.
Please advise if this is possible and what model in your stock to order.
Thank you for any assistance you can provide.
William
