Window Spring

Question

My window springs are breaking on my windows.  The spring is encased in a plastic tube.  Do you have window spring replacements and tools to install?

I think we can help, yes. It's tough to tell what you have while it's still installed in the window but it looks like a tilt window spiral balance. If I'm right, then you want either the Series 900, with a 3/8" diameter outer tube, or the Series 600, with a 9/16" diameter outer tube.

Regardless of which size you have, you also want a 75-006 charging tool.
