I'd like to replace the balances in a few of my windows. They have 28D stamped on them. Thank you for your help!

Take a look at our S380-29 Channel Balance. Look over all the dimensions, especially the 1" depth of the bottom nylon shoe, to confirm this is the balance you need. Choose a new stamp option of 2840.
