Abstract
Abstract A floor distribution box adapted for securement in a channelway defined between opposed cells of a corrugated floor structure wherein the channelway has a bottom wall and opposed outwardly inclined side walls having opposed aligned access openings therein. The floor distribution box comprises opposed transverse walls, a top wall having an outlet opening, a bottom wall, and outwardly biased displaceable end walls secured for inward pivotal displacement. An access opening is provided in each of the end walls and is provided with engagement members in the perimeter thereof for engagement in a respective one of the opposed access openings of a channelway. The outward bias provides a snap-fit engagement of the engagement members in the aligned access openings for retention of the box across the channelway.
