A multifaceted modular enclosure frame which is constructed of a latticework of identical cross-sectionally configured frame sections that include an inherent integrally formed guide system for proper installation and positioning of sub-panel mounting boards within the enclosure. Each frame section defines an interiorly disposed guide channel and mounting flange, an exteriorly disposed corner flange, and an exteriorly disposed flange trough, while maintaining an open design and a cross-sectional configuration which mates cooperatively with other identically configured frame sections to provide an integral mitered corner which is devoid of separate corner adapter inserts. The interiorly disposed guide channel provides the integral guide system for the sub-panel mounting boards which are received within the enclosure. Each corner flange defined by such frame sections provides an exterior surface upon which mounting blocks are carried to provide for complete external connection of enclosure wall panels thereto. The exteriorly disposed flange trough provides a sealing surface for such wall panels and prevents liquids from pooling up against, and deteriorating, the enclosure gaskets.
