There are a couple of different types of extension rods for ceiling fans. One of these is called a downrod, and it extends from the ceiling to the fan. It is made of a metal pipe that connects the fan motor housing to the ceiling mount. You should be sure to measure the distance between your ceiling fan and downrod and choose the right one for your space.

Downrod
When it comes to ceiling fans, a downrod is an essential accessory. The downrod will lower the ceiling fan’s height and prevent it from hitting an angled ceiling. You can purchase a downrod that is as short as six inches or as long as 120 inches. The length of the downrod will depend on the fan and the room.

A downrod is typically half-inch or 3/4-inch in diameter, but some ceiling fan manufacturers offer one-inch downrods. You should ensure that the downrod is the right size for your fan, and choose one made by the same manufacturer as the fan. You can choose between threaded and non-threaded downrods, and both types are safe to use. The downrod will be secured to the fan with set screws or hitch pins.
Extension rod
When you want to hang a ceiling fan higher than the normal height, you need to use a ceiling fan extension rod. These rods can be as short as six inches and as long as 120 inches. They are used in rooms where the ceiling height is greater than three metres. They replace the standard downrod that comes with the fan.
A ceiling fan extension rod helps to increase the height of the fan and also helps to improve the efficiency of the fan. In order to get the most from a ceiling fan, the height must be right. If the fan is not positioned properly, it may cause vibration noise in the ceiling and will not provide the desired air circulation.
Downrod size
If you plan on hanging a ceiling fan, you’ll need to determine the downrod size for the space in which it will be installed. Most ceiling fans hang eight to nine feet above the floor, but if the ceiling is higher than that, you will need a longer downrod. Regardless of how high your ceiling is, there are a few simple guidelines you can follow to get the correct length.
Before buying a downrod, you’ll want to take into consideration several factors, including the ceiling fan’s interior diameter. You should also consider whether the downrod is threaded or non-threaded. The length of your downrod should be about two inches longer than the diameter of the ceiling fan.
Safety distance
The safety distance of ceiling fan extension rod is a crucial factor when installing a new ceiling fan. The recommended distance is around 2.2 metres. However, some models are supplied with shorter rods to accommodate rooms that are taller than three metres. These need to be positioned at least 20cm from any furniture or walls.
In addition to the safe distance, the downrod should be long enough to reach the ceiling. This will help stabilize the ceiling fan and decrease the risk of wobbling. It also ensures the proper distance between the blades and the ceiling or floor. The recommended distance is seven feet, although it can go up to nine feet.
Installation
When installing a ceiling fan, the first thing you should do is determine what height you need the fan to be. Some models will come with adjustable height rods, while others will require an extension rod. Make sure to measure the height of the ceiling and select a rod based on its diameter and length.
The height of the ceiling fan will determine its efficiency. If the fan is installed too high, it will not provide enough airflow. To overcome this, an extension rod is needed. It connects the motor housing to the ceiling and will prevent resonant vibration noise. This will also ensure that the fan runs smoothly.
