Abstract:
1. An extendable electrical box comprising: an electrical box comprising four side walls, two open ends to an internal box space having a first depth, a mounting structure attached to at least one side wall of the four side walls of the electrical box, the mounting structure configured to mount the electrical box to a vertical wall structure such that the open end faces are oriented substantially perpendicular to the vertical wall structure, and tracks defining a recess on an outer surface of at least two opposing corners of said electrical box, the tracks each having a longitudinal dimension and extending between the open ends perpendicular to the two open ends and extending from the respective open end inwardly toward the internal box space, a slot formed in two opposing side walls of said electrical box and extending from each open end; and two extendable first rings slidably mounted on the outer surface of said electrical box, each comprising inwardly angled guides received in a respective track of the electrical box, the extendable first rings each continuously surrounding one of the two open ends of the electrical box and slidably coupled with the electrical box via the sliding mechanical cooperation of the one or more inwardly angled guides with the one or more tracks such that sliding either of the at least two extendable first rings in relation to the open ends of the electrical box expands the electrical box from the first depth to a larger second depth, each extendable first rings including a guide on an inner surface of two opposing walls of said extendable first rings, each said guide having a screw hole for receiving a mounting screw and supporting an electrical device, each said guide extending through a respective slot in the electrical box and slidably received in the respective slot.
