Extended-Travel Channel Balance Quote

Hello there!

This doesn't appear to be an extended travel channel balance. It looks like you have a stock balance such as our S380-28 or S385-28 depending on the depth of the bottom shoe. Measure as shown below to see which one you'll need for this repair. The 27 9 stamp on the metal channel doesn't match our rating system so you'll need to weigh your sash and refer to the chart under the product description on the S380 and S385 store pages to determine the appropriate spring strength option for your balance.
