Ideal for 11 ft ceilings, this 1/2 in ID by 24 in white extension down rod maximizes your ceiling fans cooling benefits by providing the proper height. It features a white finish for a clean complement to your existing ceiling fan. Tapered threaded ends ensure a deeper connection and stronger bond for maximum durability. 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.
