What type of ceiling outlet box should I use to hang my fan?

We recommend a standard UL-listed, fan-rated outlet box be used and installed onto a beam or joist. The outlet box should be marked acceptable for minimum fan support of:

70 lbs (31.8 kg) for any I6 fan

70 lbs (15.9 kg) for any ES6 fan

35 lbs (15.9 kg) for any Haiku fan

35 lbs (15.9 kg) for any Haiku L fan

35 lbs (15.9 kg) for any Mammoth fan

Most outlet boxes commonly used for hanging light fixtures are not rated for fan support and may need to be replaced.
