The system depends on a hidden internal system:

• The Box Frame: The external frame that houses the sashes.
• Weights and Pulleys: Lead or iron weights hidden inside the box frame, connected to the sashes by cords or chains.
• Parting Beads and Staff Beads: Small strips of wood that hold the sashes in location and allow them to slide without rattling.
