Constructed with a durable steel channel and internal spring mechanism, this balance provides long-lasting performance for residential window applications. The mill finish housing ensures durability, while the integrated winged end caps help maintain proper alignment and secure positioning within the window track. Common stamped numbers such as 1120 or 11B assist in confirming compatibility with existing balances.

All sash weights are based on using two balances per movable sash. For best results and to prevent uneven tension or binding, it is recommended to replace balances in pairs. Balances without wings may also be used in windows originally equipped with winged versions, offering flexible replacement options.
