What are the dimensions of this box? The drawing provided above is too small to read. If the box is actually 3-3/4" wide and the installation instructions say to cut a 3-3/4" round hole in the ceiling then there would be no material to hold it in place.

If the C118WAC was mounted in the ceiling to a structural member with 4 #8 1" screws through the bottom of the box, would this allow me to increase the fixture weight of the box?

Asked by: franklin2022

The C118WAC box can be rated above 6 pounds but below 50 pounds for in wall use only. "Old work boxes" Can NOT support a fixture of 50 pounds or more in a wall. Can NOT support a fixture of more than 6 pounds in a ceiling.

Someone needs to look at something with the C118WAC. It no longer fits in a 3 3/4 hole. The plastic for the support of the swing brackets is enlarged from what it used to be, making it no longer for in the hole.

We will have our Engineering department look into this and thank you for notifying us.
