Ceiling fan bracket heavy duty

[JCQuick]

I just bought a 84" ceiling fan for my shop. I have very easy access to my truss's as i don't have a ceiling (yet) the new fan weighs 86lbs i've seen some steel brackets but most only support 70lbs or less. This place is so good for ideas I thought I would ask the GJ. Give me some ideas

I would suggest a wood cross brace and a fan rated box screwed into it.

What does the manufacturers instructions say? That is the place to start.

it comes with a bracket that holds the down rod and it is steel I just don't feel good about screwing that to a electrical box

I just checked home depot’s site.

All the fan rated boxes they sell are max 70lbs...

What does the bracket look like?

All the fan rated boxes at home depot are max 70lbs so i wouldnt just screw it to any box.

Most industrial style fans don't attach to the box itself. Many use a J hook screwed into something structural. The box is just there for connections.

Find out how your fans mount.

Still asking what the instructions say, the NEC does require that listing and labeling instructions be followed.

I would mount that bracket to a 2 by wood something trust or other with inch and a half by quarter lag bolts and the electrical box next to it just for wire connections

Have you checked with an electrical supply house?

The instuctions say screw the included mount direct to the electrical box i don't trust that

JC I’ll text you.

OK i should have done this to start here is a pic of the bracket that came with the fan and the truss location I want to mount it right now i'm thinking a 2x6 between the truss and bracket mounted to that. Oh and its the center of a vaulted ceiling BTW

 

[wyliesdiesels]

That looks like a standard drop ball bracket for a fan. The trouble is you’d be hard-pressed to find a J box that supports more than a 70 pound fan.

These places need to be in a J box…

I'd add a safety chain or cable for extra insurance.

the down rod has a safety cable attached to it

Maybe thru-bolt the electrical box to some blocking? Heck, I would thru-bolt the bracket to the blocking also! That way you are not relying on the strength of the electrical box to support the load. I don't think this will violate any NEC provision?

Lock nuts or loctite and call it good. 2x6 blocking between trusses w/ (2) 1/4" lag screws or equivalent will be good for some 400 lbs+ or so.

Try looking at the Westinghouse Lighting 0180000 Heavy Chandelier and Fixture Brace .

It's rated at up to 800 lbs. We used them to install large chandlers that ranged from 200 - 500 lbs.

This! Just a couple screws in the back of the box to hold it and the wiring, beyond that they would serve as locating dowels to line everything up when you run a pair of 1/4-20 hex cap screws through everything backed with fender washers and nyloc nuts.

Our local inspector would red-flag that in a heartbeat.
I guess I dont understand why the fan manufacturer doesn't have an answer for you. Any company that makes 86 pound fans MUST have a mounting solution.

That's more or less what I was envisioning. I've looked at several cut sheets for some 800 lb+ chandeliers, but never bothered to look at J box.

Also, if OP has welding capabilities, a simple steel bracket with clip angles into the bottom chords of the trusses is easy to fabricate.

This style of box has the weight bearing portion of the fan being held directly to the wood with wood screws, not to the box. This is the type i used for a ceiling fan in my porch. Not sure why its rating is only 70lbs though. To test I literally hung my 195lb self from the fan bracket and it was just fine. No qualms about hanging my 50lb fan from it. Mine is attached to a 2x4 setup as blocking between 2 roof trusses so I could center it perfectly.

I'd put a 2x6 block between the truss lower cords, bolt the bracket to that, drill a hole right in the middle and mound a box on top of the board. Run the wires through the 2x6.
