2107763 9218392 PCTABS00016 A rigid plastic enclosure made from flat blanks (10) which is particularly well suited for use as an electrical or electronic component enclosure. The top, bottom, back, and side walls (14, 16, 18, 20) of the enclosure are parts of a unitary structure made by cutting and/or routing a single sheet of plastic which can be folded and locked into an open-faced, box-shaped structure by hand without using tools. A cover (56) or face plate can be fastened to the folded and locked structure to complete the enclosure. Because the enclosure is constructed from plastic, holes (51) can be easily drilled into its walls, eliminating the need for providing knockout holes at predetermined locations. Because the sidewalls (14, 16, 18, 20) can be folded away from the interior of the enclosure, it is easier for electricians to install electrical and electronic devices into the enclosure and to perfom wiring operations within the enclosure. The invention is lighter than steel enclosures, and can be shipped and stored in a flat configuration, thereby saving space and allowing for lower shipping and handling costs.
