A home owner from San Jose CA says:
Hello, my name is Omer. Need your teams help with replacment parts. A balance spring for a single hung window and a top Sash Channel Balance guide. Window discription below.

AAMA Certification Program
MFR: PHP-28 Series:810S
S/N for the balance spring is 28 9 bv cmc

The balance lenght is 29 inches (not including plastic parts). I have attached pictures of the channel balance shoe and top.

Hey, thanks for posting, Omer. I've narrowed this down to two possible channel balance Series: either our Series 380 or our Series 385 balances.

Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 380 uses the 15-005 while the Series 385 uses the 15-004. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match.
15-004 and 15-005

I will be ordering 2 of 385-29 & 2 of 380-29 for the balance spring. However, not sure what "stamp" option to use? Please recommend.

Also, still need the Top Sash Channel Balance guide recomendation. Please support

For the top sash guide, see our 18-171. We don't have an option that corresponds to a 28 9 stamp, so you will have to weigh your window sash in order to determine which is best.
