Unknown Sash Weight/no stamp

Question

Good evening.
I am looking to replace both channel balances on two large windows in my home. The old balances have no stamp and I am unsure of the sash weight. The DR window is approximately 50"X31" and the study window is approximately 50"X25". Single pane. The associate at Home Depot suggested a 23" series 385 channel balance, option 2240. Any advice you could provide would be greatly appreciated. Thank you.

Thanks for your inquiry. The "2240" option on our S385-23 channel balance indicates that the spring strength will hold a sash weighing 19-23 pounds. Does that sound about how much your sash weighs? If you're unsure, the only way of confirming the precise weight of your sash would be to remove it and weigh it on a scale. You also may send us photos of your balance for us to take a look at to see if there any other suggestions we can offer.
