This Westinghouse Lighting 3/4-Inch by 36-Inch Extension Down Rod helps maximize your ceiling fan's cooling benefits by providing the proper height. It features an antique brass finish that complements existing ceiling fans and tapered threaded ends for a secure connection. The extension down rod measures 36 in long by 3/4 in in diameter, and is ideal for rooms with 12-foot ceilings. It can be used with Westinghouse or other ceiling fans that require a 3/4-inch diameter ceiling fan extension down rod. For optimum performance and safety, ceiling fan blades should be at least 7 ft from the floor but no higher than 8 to 9 ft in order to best cool a room. For ceilings 9 ft and higher, an extension down rod is required to bring the ceiling fan down to the proper height above the floor.
