Hey there. This old rod balance is no longer made, but the Series 770 Channel Balance can replace it. Measure the length of the rod to determine the balance length needed. To know what stamp option to select, weigh the window sash the balances support. Let us know if you have further questions.

The balancer is 26". I wasn't sure if the stamp I sent indicates the weight of the sash.

The stamps on the old rod balances unfortunately do not correspond to any weight rating. You must weigh the window sash to determine the proper stamp option to select, based on the information on the S770-26 shop page.
