channel balance questions

Question

Hi, I am in need of replacing a window balance with code #3390. Based on your forum I may be able to use one of these products. Two questions I have:

I am unable to remove the window completely because the shutters installed does not allow me enough space. Do you know if I can install the balance with the window shut, slide the window up and then back down? From what I can tell, there appears to be enough space for me to hook the bottom of the balance, compress and then hook up the top while the window is shut/down.
Because I am unable to remove the window I am not sure how much it weighs exactly. I see the highest you make is #3360, how do I get a hold of #3390?

Thanks!

Unfortunately, you will need to remove at least one side shutter in order to replace these balances. There is no other way.

As for the stamp, this is an old stamp that isn't used on modern balances. One of our stamps may still work, but you will need to weigh the sash to confirm the proper option.

While you have the balance out, I also recommend you look over your top and bottom nylon ends to confirm that the S380-34 you're looking at is right. This comes with the 19-005 top and 15-005 bottom. The stamp has no bearing on what these nylon ends are, so you will need to compare physical design and size.
