Non tilt window channel balance 30XHD?

Hi there! You won't be able to replace your channel balance with a coil balance, no. They wouldn't be easier to fit in the window jamb because they wouldn't fit at all to begin with. You are pretty much stuck with this style unless you get an all new window.

With that said, the match for your channel balance is our Series 751.

Hey, Natan. A stamp of 30XHD usually indicates a metal channel length of 31", so you should double check that just to be sure. I know that's a little confusing but the first digits of the stamp on this kind of balance are typically one less than the length.
