window counterweight help

A home owner from Saint Louis, Missouri says:
Hello -
I am looking for parts for a few aluminum double hung windows. Lower sash won't stay open. Coils have become disconnected from sash.
I've attached a few photos.
I cannot find any identifying markings on windows.

Hopefully you can help.

If your coil balance springs aren't broken, then your pivot lock shoe might be broken. See our 15-141 balance shoe for a possible replacement.

Now if the coil springs are broken, then you are going to have to replace the springs and acquire a new pivot shoe, since the springs you have now are discontinued. I would recommend our 15-140 pivot shoe and Series 150 coil springs. To determine the proper Series 150 option, refer to the number printed on your current spring.

Other fittings you might have to replace are our 15-143, 15-144 and 15-145. To make it easy, you will need a pair of needle nose pliers to install the coil springs to the pivot shoe.
