• Sash Cords and Weights: In conventional windows, lead or iron weights hidden in the frame balance the sash via a cord and pulley-block.
• Spring Balances: A modern alternative to weights, using a tensioned spring to hold the sash in location.
• Sash Horns: Decorative protrusions on the bottom of the upper sash, initially designed to reinforce the joints in much heavier Victorian glass.
