The synchronisation system for Push-open Futura runners has been developed to ensure that drawers of any width can be opened with minimum effort. The system links the two runners, which thus become a single element; a pressure at any point of the drawer frontal (even at the extremities), is sufficient for the Push devices to release and consequently for the drawer to self-open. The synchroniser can be used with any drawer width; its functionality is at its best with wider drawers.
