Ceiling – how to hang 200lb chandelier

ceilinginstallationload

I'm planning to buy crystal chandelier that weigh 200lb. We will be replacing existing chandelier in the two storied foyer (height 18 feet). Current chandelier is installed using electric metal box on 2×6 inch lumber installed between the joists. I have good access to attic and joists are 2×6 inch and spaced 16" apart. There is no other load on the joists (than the roof). Chandelier installation braces sold in stores and online are at the most rated for 150lb capacity. Questions i have:
1) Can I hang 200lb chandelier safely on 2×6 inch joists without causing damage to the joists (by overloading them) or to ceiling (because of joist deflection)?
2) what type of hardware available for installing heavy chandelier – any link appreciated.
3) seems like standard method of installing chandelier using electric box using screws may not be appropriate for 200lb chandelier – what technique should one employ to install heavy chandelier?
4) Is this something a DIYer can do it (i installed one chandelier in dining area) or are there more structural issues that I need to tackle?

Thanks in advance.

  1. Check with the manufacturer of the fixture. They should have some design parameters.
  2. If they are modern day conventional residential roof trusses, I recommend contacting a mfg of same. See what they say.
  3. I personally would take a 3' piece of standard #2-and-better 4x6 lumber, free of flaws, lay it perpendicular across the top side of two trusses to use as your main support. Drill and screw in place. A standard 4-square metal box with a round mud ring will support the fixture.
