Abstract
Abstract A housing that can be readily assembled for packaging equipment, such as electrical components and meters. The housing includes a pair of spaced end rings, each of which has an endless groove in the inner wall thereof. A thin elongate shell is positioned within the groove and end plates are carried adjacent ridges on the opposite side of the end rings. Bolts extend through the panels for drawing the panels flush against ridges carried on the end ring and supporting panel boards within the housing. Thus, an airtight package or housing can be readily assembled.
