Would like to replace this 25 4 HP Window balance

A home owner from Danville, CA says:
This is a 26" x 1/2" window balance. I need to replace these on 2 windows. The stamp is 25 4 HP Caldwell.

Thank you.

Thanks for posting! Before I can offer an applicable replacement for this channel balance, I just need to know a bit more information about the bottom attachment. Please take a look at our 15-004 and 15-005 channel balance shoes, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?

Please check image. I think its the 1-3/32".

These are pretty heave windows.

Thank you,

Great. In that case, check out our S385-26 with a 2540 option. What do you think? Does this look good to you?
A home owner from Danville, CA says:
Looks great. Do I need to purchase the plastic parts, as well?

Well, it looks like that specific piece is in good condition, but if you think it needs replacing or if its opposite side is damaged, then you might want to check out our 18-008. I think this looks pretty close but let me know if you agree.
