Why would one use a Carlon SuperBlue old work box as opposed to the cheaper Zip Box? Why would one need to use a more rigid box in old work?
"Carlon SuperBlue boxes are so strong they won?t crack or break, even in extreme environments. So rigid, they resist flexing and hold their shape even under the worst conditions."
