A handy person from Jacksonville FL says:
I have several balances that no longer hold the window. Specifically, they do not catch the window at the low end of window. Do I need to replace the balances? Also, I have a few where the top piece has cracked off. Can you help? Image loaded shows a number on the base of the balance as 29 4

Thank you for submitting your photos.

Can you please give us the length of the channel portion of your balance only?
A handy person from Jax, FL says:
I am not at the house, but believe the channel portion is 30 inches long...

It appears you'll need the S385-30 Channel Balance with the stamp option 2940.

Be sure to check the condition of your top sash guides, as they may need replaced as well. If so, look at the 18-044 and the 18-166 Top Sash Guides.
