How To Install Expandable Mounting Bracket for Ceiling Fan

Installing A Expandable Mounting Bracket


Replace the existing electrical box if the box itself is made from plastic. Although, there are some plastic boxes that are rated for ceiling fans, a metal one is still recommended. If in place is already a metal electrical box , make sure it is securely braced; after all, the weight of the ceiling fan is not light, especially when the fan is on high.

You may not need an expandable mounting bracket if the installation is under a ceiling joist. A joist is running across the hole. A thin fan rated metal electrical box will work.

Most of the time, a joist is next to the hole.

As recommended, before beginning any project, always read the manufactures instructions. Some local building codes may require a permit. If at anytime you don’t feel comfortable working with electricity, then contact a licensed electrician.

  • Pliers


Step 1

Turn off the power at the circuit breaker. As always, test with a circuit tester to be positive the power is off.

Step 2

If you are starting with an empty hole with no existing electrical box or light fixture, move to the next step. If not, continue reading.

You will have to remove the screws to the mounting bracket to loosen the fixture. Next disconnect the wires to the electrical box and remove the light fixture.

Remove the box. It is usually attached to the joist next to the hole. You may have to use a piece of scrap wood and hammer to tap the box loose. Tip: To stop the drywall from cracking, you may have to cut around the outside of the box and remove the drywall. If the ceiling does get damage, you can cover the area with a medallion.

Step 3

Insert the brace into the opening in the ceiling between the two joists and rest the end supports on the drywall (ceiling). Tighten the bar by hand until it gets too hard to turn. Continue tighten the bar with a wrench until the ends digs in and is fully tightened.

Step 4

Put the junction box (electrical box) on a solid surface and remove the knock out on the back of the box, using a hammer and a screwdriver. Use pliers to pull the tab out. Use a cable clamp in the opening. Then the box is ready to be hang.

Step 5

To attach the box, use the u bolt that comes with the kit over the brace. Feed the cable through the cable clamp and tighten the screw.

Slip the box over the u bolts and thread the nuts on to the bolts and tighten.

In conclusion, a ceiling fan can be very heavy depending on materials used and overall size. That’s why it is very important to have a secure way to hang the fan.
