Questions & Answers

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.
