Constructed with a durable mill finish, this replacement balance is built for dependable performance in residential and commercial window applications. With a 35-inch channel length and a sash weight capacity of 14–18 lbs, it is designed to replace balances stamped 3420 or 34B, ensuring compatibility with many standard window balance assemblies.
All listed sash weights are based on two balances supporting one moveable sash. For proper window performance and balanced movement, it is recommended that sash balances be replaced in pairs. Mixing old and new balances can create uneven spring tension, which may cause the window to bind in its channels and become difficult to operate.
