Window balance

Question

There is a PAT #5.737.877 on one piece that holds the string and/or spring. I am working with 2 windows. As far as I can tell, I measured one 18", other 27".

Hello,

The old-style crossbow balance shown in your photos is no longer available but you can follow the conversion video below to use our S795 balances as long as your spring has a diameter of 1/2". Take a look and thanks for posting!
