Stackable like-ganged electrical boxes
摘要:
A method and structure of a system of electrical boxes having at least two screw boss channels and at least two screw protrusions wherein the screw boss channels are complimentary shaped to the screw protrusions for selectively nesting like-ganged electrical boxes while preventing nesting of dislike-ganged electrical boxes for more space-efficient storage of electrical boxes while increasing inventory control and accuracy.
