Constructed with a durable mill finish, this replacement balance is engineered for dependable performance in residential and commercial window applications. With a 33-inch channel length and a sash weight capacity of 31–35 lbs, it provides reliable support for heavier window sashes. This model comes with wings, which help secure the balance properly within compatible window channel systems.
All listed sash weights are based on two balances supporting one moveable sash. For optimal performance and proper window alignment, it is recommended that sash balances be replaced in pairs. Mixing old and new balances may cause uneven spring tension, which can lead to window binding and difficult operation.
