ABSTRACT:
The exhibition hall electrical floor box includes a housing having a plurality of chambers therein. Each chamber accommodates a particular type or types of electrical connection therein. Chambers adapted to engage a cylinder type connector therein each have a fitting therein positioned in such a manner as to cause the connector to lie diagonally across corners of the chamber horizontally as well as vertically to produce a box having a significantly decreased height, such decreased height requiring significantly less concrete to be poured to create a flush mounting of the box within the floor.
