Broken shoe

Greetings, Martin. It appears you have the old Silverline mechanical Series 4000 window. The pivot shoe previously placed in these windows have been replaced with the 15-046 along with the Series 600 spiral balance. Please provide us with the tube length and the color bearing of your spiral balance to choose the appropriate balance. It seems your color bearing is red. Please confirm if this is correct. We also would like to guide your eyes to our 75-006 charging tool. This tool will help with the replacement of the balances. If you should need any further assistance, look into our media guides on this page.
