This movement is facilitated by lead or iron weights concealed within a hollow "box" frame, connected to the sashes by long lasting cords running over wheels.

The Restoration Process

The systematic approach taken by specialists generally follows these phases:

1. Assessment: A comprehensive study to recognize rot, structural damage, and hardware functionality.
2. Taking apart: Careful removal of staff beads, parting beads, and the sashes themselves.

4. Balancing: Re-weighing the sashes and changing the internal weights to guarantee the window "drifts" easily.
