If your ceiling is built high, and your room is on the larger side, then you may require downrod ceiling fans . Standard mount typically features a 4 down rod lowering the fan slightly from the ceiling. An extended mount utilizes down rods to lower the Ceiling Fan from the ceiling down to the ideal 7-8 from the floor. These mounting systems are used with ceilings of higher than average height. (9and higher).
To determine which mounting system is right for you, consider your ceiling height. For ceilings taller than 8 feet, you hang the fan from a drop rod. The distance the fan should hang down from the ceiling will depend on the ceiling's height (but never lower than 7 feet from the floor). Here are the suggested lengths for a downrod ceiling fan ranging from 9 to 13 feet:
| Ceiling Height (feet) | Drop Rod Length (inches) |
| 9 | 18 |
| 10 | 24 |
| 12 | 36 |
| 13 or more | 48 |
Check if you have a ceiling box, and the appropriate framing, to safely support your downrod ceiling fan . With the power off, remove the light fixture. Use a hammer and a heavy screwdriver to break up a plastic box. Use a mini-hacksaw to next to an inadequate, side-mounted box. Remove the wiring from the old box and pull it down through the opening. Mount a wiring connector in your new ceiling box. Feed the cable through that and tighten the clamp. Mount the new box according to its manufacturer's instructions.
If the fan is located on an ordinary ceiling box, there is the risk that his maneuver will eventually loosen the box or even cause the fan to abruptly drop from the ceiling. Even with the more solid mount, there may be eventual loosening of the bracket which might not cause the fan to fall but may cause some wobbling. Remember this bracket is not designed to take that sort of stress.
