A replacement window spiral spring balance is a component of a double-hung window that helps to counterbalance the weight of the sash. It consists of a coiled spring inside a metal tube that is mounted to the window frame. The spring is under tension and exerts a force on the sash, helping to hold it in place at any height along the track.
Over time, spiral spring balances can wear out or become damaged, which can cause the window to become difficult to operate or to remain open or closed. In such cases, the spiral spring balance needs to be replaced.
To replace a spiral spring balance, you will need to remove the window sash and detach the old balance from the window frame. You will then need to measure the length of the old balance and purchase a new one of the same length and weight capacity. The new balance can then be installed by inserting it into the metal tube and attaching it to the window frame.
It is important to ensure that the new spiral spring balance is installed correctly and that it is the correct size and weight capacity for the window sash. If in doubt, it is recommended that you consult a professional window installer.
