The mill finish housing provides strength and durability, while common stamped numbers such as 1220 or 12B help confirm compatibility with existing balances.

All sash weights are based on using two balances per movable sash. For best performance and to prevent uneven tension or binding, it is recommended to replace balances in pairs. While some balances include winged end caps, this standard version can also be used in applications where winged balances were previously installed.
