Simonton windows

Thanks for your post! The part in the window track is the coil balance shoe. It can be replaced with the 15-111 Pivot Shoe. It is compatible with the Series 160 Coil Balance.

You'll need to look for a stamp/marking on the metal to determine the correct replacements for the new assemblies. If there are none, please see the following video tutorial for instructions.
