An expandable power and data center (300) is adapted to be mounted within a slot (304) of a work surface (302). The power and data center (300) includes a stationary housing (306) and a carriage (328). The carriage (328) includes socket areas where power receptacles (338) and data ports (340) can be inserted. A top surface (330) of the carriage (328) and a top surface (350) of a frontal cover (348) form a pressure area (360). With the carriage in a closed position (328), a user can exert a downward pressure on the pressure area (360), causing the carriage (328) to move to an open position. A damper (368) restricts the speed at which the carriage (328) moves between the closed position and an open position.
