Can you please help me identify these?

Question

Hi I need to replace the sash balances in my windows.
The stamp is 2950. The width is either 1/2 in or 5/8. They are 30 in long.

Thanks for your post! This window balance is assembled similarly to the S378-30, S380-30, and S385-30. To determine which of these is the correct series, you'll need to measure the depth of your bottom shoe.

You can select the 2950 stamp option.
