Harcar window balance

Thanks for writing in! Your window balance has winged top and bottom attachments like our S378-30, S380-30, and S385-30. To determine which of these is the correct replacement, you'll need to confirm the measurement for the depth of your shoe.

You can likely use the 2920 stamp option which can support a sash weighing 12 to 16lbs.
