August 25 - Many of the closets have switches on the doors so when the door is opened, the light illuminates. To do this, a notch is cut in the stud for the switch box. On most closets with double doors, we have put a switch on each door, so if either door is opened, the light is powered. Note the steel nail plate. This protects the wire behind it from any drywall screws that might be placed near it.
