Parts

Thanks for writing in! These window balances are a match for either the S380-27 or the S385-27. To determine which of these is the correct replacement, you'll need to confirm the depth of your bottom shoe.

The 2620 stamp should work for the window. A pair of these will support a sash weighing 9 to 13lbs.

The top sash guide reminds me of the 18-171 Stepped Sash Guide. To confirm that this will work for the repair, carefully look over the specifications (on the website) and compare them.
