Installing a ceiling fixture on a cathedral ceiling may require additional hardware.
Since most fixtures such as lights or ceiling fans are designed to hang from flat ceilings, installing them on cathedral ceilings may require additional hardware. Unless the fixture involved is already intended for a cathedral ceiling, you will need to use a cathedral ceiling block, which looks like a triangular metal or wood box about the size of a ceiling light.
Instructions
1. Turn off all power to the ceiling electrical box, by flipping off the appropriate circuit breaker in the house circuit box or pulling out the fuse, if your house has a fuse box. Test the fixture with a fresh light bulb to make sure it's dead. Remove the existing fixture by taking out the mounting screws and disconnecting the wires, so there's just an electrical box. Let the wires dangle down from the electrical box.
2. Hold the cathedral ceiling block against the electrical box, lining up the screw holes on the block's upper side to the mounting holes in the electrical box.
3. Secure the cathedral block with the provided mounting screws, putting them through the line-up holes.
4. Pull the wires down through the center opening of the block. Spread them out so you can see them all individually.
5. Wire the fixture as instructed on the fixture packaging (generally, black wire to black, white to white), twisting wire nuts over the connections and wrapping them in electrical tape. Twist the bare copper grounding wire around the green grounding screw on the fixture.
6. Hold the fixture up to the ceiling block. Line up the mounting holes of the fixture to those of the ceiling block (the positions are standard). Affix the fixture with the provided screws. Turn the power back on.
