We supply down rods in the following lengths: 150mm (15cm) which comes as standard with the Monaco fan, plus 600mm (60cm) , 1200mm (1.2m) and 1500 (150cm) down rods in either Brushed Steel, White or Black. A down rod extension pole is an add-on purchase that is only ever needed if your ceiling height is 2.7m or higher. In such cases, adding an extension rod to bring the ceiling fan lower will dramatically improve its airflow effectiveness. The Australian/ New Zealand Standard requires that a fan should be installed so the blades are at least 2.1 metres or more from the floor. Try to keep the ceiling fan within the optimal height of 2.1m to 2.4m from the floor to the blades of the fan, with the furthest effective distance reaching up to 2.7m (2700) from floor.
