Channel Balance Replacement

Thanks for your question. The top of your balance channel is missing. If it looks like our 19-002, you will need our Series 390-25" side load balance.The spring weight for 2490 32 is (2465) for a sash weighing between 30-33 lbs. Also check if your take-out clip, 16-002, and top sash guide are OK. Please look over our media guides for further help.
