Hi,
We have 14 PGT single hung windows that all have some problem. Some with broken top sashes and run-away balances and some with stuck balances. Before diving into a repair I would like to have replacement parts on hand. I am not confident in selecting the correct parts and would like your help. Here is what I know:
PGT
I think they are series 4000 as per the attached picture.
single hung
One of the run-away balances has the number 3520 stamped on it

I will need balances and top sashes.

I think your replacement parts are:
S350-20 and 18-110

Thanks in advance.

Regards,
David

Thanks for contacting us. I'm afraid I cannot identify what you have based on that sticker alone. I can say that PGT windows have been known to use our Series 395 balance and 18-015 top sash guide, but considering that these differ from the parts you picked out I think it would be best if you were to show us a few pictures of your hardware. Please make sure we can clearly see both ends of the balance. Please also provide measurements for all your hardware, especially the top sash guide.

Thank you, I have since pulled a balance and measured the top bottom and length. Your are correct. The corresponding part is series S395 and the top sash is 18-015.
I might add that these PGT windows disassemble very easily exposing all replaceable parts and anyone with basic repair skills can repair them.
