27C spring balance

Handy Person from Spring Texas
Channel Block and tackle window spring balance is broken in my window and my window won't stay up.  So, one picture is of the numbers/markings on the spring balance casing, the other is the sticker on the window it was in.  It is a tilt window.  I need the part number to order two of these, and any additional parts like shoes and the installation tool to install it with.Thank you.

Hello,

We'd be happy to help but we'll need more information to get started. If you could show us the fitting at the end of the balance pulley that connects to the pivot shoe, that will help us narrow down your options. Please also confirm the length of the metal balance channel. Thank you!
