Sash balance

Thanks for reaching out! Your balances appear to be a jamb liner spring. I'm sorry that say that we are not able to provide you with a replacement for these balances. 

Since these look like they are installed in a wood window, you'll need to attempt to contact a local mill work that might be able to assist with getting your set up with the balances you need.

I do apologize that we cannot be of assistance with your repairs.

Please let me know if you have any questions.
