Can you send a detailed dimensioned drawing? Concerned with how far the wings spread fully opened. Replacing a fixture that was installed with no box. Feed is attached to stud; center line of mounting space is only 3/4" off the stud.

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.

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