Thread: Old work ceiling box

  1. #1

    Old work ceiling box

    Is it illegal to use an old work ceiling box to support a light fixture?
    The only support is the wings on the sheetrock. I think you should only use them for smoke detectors.

    One example:

    "The B618R is a round old work outlet box and is not listed for fixture support in
    the ceiling. Only approved ceiling boxes are allowed to support fixtures in the
    ceiling. These boxes will be permitted to support a minimum weight of 50
    pounds. The B618R can be used in the ceiling as a junction box. Do not hang a
    fixture from it since it relies on the strength of the ceiling itself."

    If the box is the T&B 618R or 618RP, the round plastic rework box is not listed for fixture support. Take a look at the bottom of page eleven of these catalog pages.

    If you're using another manufacturer's box, look up the info at the manufacturer's site.

    What boxes do you use?

    Most round old work boxes are listed to support fixtures (10-15 lbs) in walls but I have never seen one listed to support fixtures in ceilings.

    I better tell people to start buying heavier fixtures.
