- Sash Cords and Weights: In standard windows, lead or iron weights hidden in the frame balance the sash by means of a cord and wheel.
- 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, originally created to enhance the joints in much heavier Victorian glass.
