Window clip off balancer

Hello there. The Spiral Balance seems to be either our Series 600 or Series 900 , depending on the outer tube diameter. See the videos on this page that detail how to remove and replace a spiral balance, as well as how to identify the right match. For the pivot shoe, please remove an undamaged version if available and show us a picture; also tell us its width and thickness. 

Thanks for getting back to us. If the shoe is 1/2" thick then I recommend looking at our 15-046 to start out with. This is 1-1/4" wide, 1/2" thick, and is fully compatible with the recommended balances.
