What is a Window Coil Spring Balance?

A window coil spring balance is a device that counterbalances the weight of a window sash, making it easier to open and close. It consists of a coil spring, a pulley, and a cord that attaches to the window sash. When the window is opened, the spring extends and the cord winds around the pulley, lifting the sash. When the window is closed, the spring retracts and the cord unwinds, lowering the sash.

There are several signs that indicate it may be time to replace a window coil spring balance:

  • Difficulty opening or closing the window: A weak or broken spring balance can make it difficult to lift or lower the window sash smoothly.
  • Window falls out of place: A failed spring balance can cause the window sash to fall out of its frame when opened.
  • Window rattles or shakes: A loose or damaged spring balance can cause the window to rattle or shake when closed.
  • Cord is frayed or broken: The cord that connects the spring balance to the window sash can become frayed or broken over time, rendering the spring balance ineffective.
