Window coil balance

A quick learner from Cary, NC says:
Hello,

I am trying to replace a broken window coil balance, please see photos attached. The metal coil is broken into two pieces. The metal coil is 1/2 inch in width. However I can't find any other markings on the metal. The lock shoe is about 1" in size and has markings of "Patent: 4,610,108" on it. It is for small single hang kitchen window.

Could you please let me know which part I need to order.

Thank you!
Hetty

Hello,

This looks like our 15-111 pivot shoe that is used with the Series 160 sash support system. Take a look at the product pages and related items section. Thanks for posting!
