Quizplus · Accepted Answer

A box extender is the best choice to bring the edge of the box flush with the wall surface when it has been installed too far back. This allows for proper installation of devices and cover plates. Installing a new box would be unnecessary and time-consuming, a wall shrinker does not exist and using a different kind of device box may not be compatible with the current wiring setup.
