Need Help Identifying Part

Question

This is a 35 inch long channel for a NUAIR window. Can you please help me identify the replacement part? I can provide additional pictures if needed.

Thanks

Thanks for reaching out! The balances you have could be either the S351-35 with a 1" shoe or the S390-35 with a 1-1/8" shoe. To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe. You'll need to select the 3450 stamp.
