Hello,

It sounds like you need replacement channel balances used to support the weight of the window sash. There's a good chance that we can help but we'll need more information to narrow down your options. To get started, please show us photos of an intact balance removed from the window, including both ends and the clip at the end of the pulley cord. See the videos related on this page to assist you. Thank you!

Thank you! Based on your photos, we recommend having a look at the S380-29 and S385-29 channel balances. The best match will depend on the depth of the bottom shoe as shown below.

Your old 28B stamp may translate to the 2820 stamp option; a pair of balances with this stamp will support a sash weighing 12 to 16 pounds. You can always weigh the window sash to confirm it falls within this weight range. 

Please let us know if you have any questions!
