Identification of replacement channel balance

A handy person from Miami, FL says:
Hi. I need to replace 2 channel balances for a single-hung window. They are stamped 2320. They measure 24" and are 5/8" depth and 9/16" wide. Please see uploaded pictures.
Thank you

Hello,

Take a look and compare the S377-24 channel balance with a 2320 strength option to your original assembly. Thanks for posting!
