What are Sash Window Balances?
A window is made up of a few parts. First, you have the panes of glass which are held in place by a frame. A sash window or hung sash window is made of one or more movable panels or "sashes" that form a frame to hold panes of glass.
A Sash, is the term that almost exclusively, refers to windows where panels are opened by sliding vertically, or horizontally, or a sliding sash or sash and case (so called because the weights are concealed in a box case).
Today, double-hung sash windows use spring balances to support the sashes, but traditionally, counterweights held in boxes on either side of the window were used. These were and are attached to the sashes using pulleys of either braided cord or, later, purpose-made chain. Double-hung sash windows were traditionally often fitted with shutters.
Acme Duplex produces 4 original sash window balances for you to use as replacements.
Why replace a Sash Window Balance?
If your windows (sashes), are having problems staying up when opened, it may be that your sash balances or hardware needs to be replaced. The sash balances hold the weight of the window pane, over time, the springs can wear out or fail. Replace your Acme Duplex or Acme Twin products with the original.
