window balance shoe

A handy person from eagle, wi says:
I was told by the builder, Bielinski, that my windows are your product. On one of them the balance shoe is broken. I don't know what to order nor do I know how to replace it once I get the part. I've been in industrial maintenance since 1973 so I can handle it if I know the procedure. I tried to find a video on your site but couldn't and the written procedure assumed I must have done this before plus I wasn't sure it was applicable to my windows.

Please see the pictures to help you identify what I need to order. In those you'll see the assembly has 31B stamped into it and the frame has a label... "Series 9103 vinyl sh, PL#050-116"

Hello!

It looks like you may have our S751-32 ribbed channel balance. This comes attached with the 15-014 by default so you'll have to remove your shoe from the window to determine if you have this or not. If it doesn't look the same or if you're unsure, show us a picture of the shoe removed from the window and we can work from there. 

Your "31B" stamp doesn't match any of our spring strength options, however. Can you weigh your sash and tell me the weight? 

We also have a video that demonstrates the installation process for this type of balance, which I will post below.
