GA Window Balance

Question

I've been told my GA original 1985 aluminum windows are hard to raise due to channel balance.  I unscrewed the top plate on one today, and almost got slammed in the face by the plate and screw under the spring pressue- cautionary tale!  I am really on the fence about replacing these windows, but maybe your answer here, as to  replacing these channel balances, will turn the corner on a decision!  It's been suggested  to lubricate the channels, but now that I see what happens when I remove, how cruddy they are after 36 years, and the fact that it shot out of there and I don't know how I'd get it reattached, and the quotes to replace being $250 per window,....Looking forward to hearing from you.

Hello,

We'd be happy to help you find the correct replacement balances. To start with, the balances in your photos are spiral balances, which use the retractable spiral that comes out of the tube housing to anchor the balances to the bottom of the window sash. Channel balances are a whole different animal.

As far as identifying your balance, it looks like you'll need either the S400-30 or S500-30, depending on the diameter of your housing tube. The S400 measures 3/8", while the S500 is 5/8". Since the colored tip of your original balance is no longer discernable, you'll need to weigh your window sash and follow the chart under the balance product page to choose the corresponding strength color option.

Once you've determined the correct balance, I'd recommend taking a look at our balance replacement guide for non-tilt windows here to help you through the process. Thank you!
