Channel Balance w/ #2990. What do I Pick?

Question

Channel Balance, Series 380 looks like what i'm replacing, but the Balance is stamped with the #2990 on it. Your list of Sash Wt. ratings doesn't go that high so which # would you suggest?

Thanks for posting. Your stamp is from an older rating system that we no longer use. To know which stamp option to select, the best thing to do is to weigh your window sash. You can then match that precise weight with one of the weight ranges listed with each stamp option on the product page. If by chance your sash's weight falls outside our options, let us know and we'll work something else out for you.
