Claim 5:
6. A modular ceiling fixture mounting device comprising:
a first tube having a cross-sectional profile that is one of substantially trapezoidal and square, the first tube comprising a first section and a second section extending from an upper end of the first section, wherein a rear edge of the first section is configured for positioning along an intersection of walls of a room, such that each rear face of a pair of rear faces of the first section abuts a respective one of the walls, and such that the second section extends angularly from the first section toward a ceiling of the room, the second section extending from the first section at from 141.0° to 145.0°, an upper edge of the second section being dimensionally longer than a lower edge of the second section, such that opposed ends of the second section are tapered, the first tube being formed by welding of the first section and the second section;
at least two mounting holes positioned in the first section proximate to the upper end, each mounting hole being aligned with an associated mounting hole, wherein the mounting hole and the associated mounting hole are configured for insertion of an article of mounting hardware for fixedly attaching the first tube to a structural element of at least one of the walls, the at least two mounting holes comprising:
a first hole positioned in a front edge of the first section proximate to the upper end, and
a second hole positioned in the rear edge, wherein the first hole and the second hole are configured for insertion of the article of mounting hardware for fixedly attaching the first tube to the structural element of the at least one of the walls;

a second tube selectively attachable to the second section distal from the first section, such that the second tube extends substantially perpendicularly to the first section into the room, an upper limit of the second tube being dimensionally longer than a lower limit of the second tube, such that a respective opposing end of the second tube is tapered;
a third tube selectively attachable to the second tube distal from the first tube, such that the third tube is substantially parallel to the walls, the third tube extending from the second tube at from 87.0° to 91.0°, an outer limit of the third tube being dimensionally longer than an inner limit of the third tube, such that a top end of the third tube is tapered and a bottom end of the third tube is substantially perpendicular to the inner limit and outer limit of the third tube;
a connector attached a bottom end of third tube, the connector being configured for selectively attaching to a fixture, such that the fixture is suspended in the room;
a first fastener attached proximate to the respective opposed end of the second section, the first fastener comprising a plurality of first fastening holes, each first fastening hole being positioned in a respective upper facet of the second section;
a second fastener attached proximate to a one of the opposing ends of the second tube, the second fastener being complementary to the first fastener, such that the second fastener is positioned for selectively attaching to the first fastener for removably attaching the second tube to the first tube, the second fastener comprising a pair of end tabs positioned in and extending from the second tube, each end tab being attached to a respective upper face of the second tube;
a plurality of second fastening holes positioned in and equally distributed between the end tabs of the pair of end tabs, each second fastening hole being threaded and in alignment with a respective first fastening hole upon insertion of the pair of end tabs into the second section of the first tube;
a plurality of fastening bolts, each fastening bolt being insertable through a respective first fastening hole and threadedly insertable into an associated second fastening hole for removably attaching the second tube to the first tube;
a third fastener attached proximate to the other of the opposing ends of the second tube, such that the third fastener is distal from the second section of the first tube upon attachment of the second fastener to the first fastener, the third fastener comprising a plurality of first fastening openings, each first fastening opening being positioned in a respective upper face of the second tube;
a fourth fastener attached proximate to the top end of the third tube, the fourth fastener being complementary to the third fastener, such that the fourth fastener is positioned for selectively attaching to the third fastener for removably attaching the third tube to the second tube, the fourth fastener comprising a pair of connector tabs positioned in and extending from the third tube, each connector tab being attached to a respective outer face of the third tube;
a plurality of second fastening openings positioned in and equally distributed between the connector tabs of the pair of connector tabs, each second fastening opening being threaded and in alignment with a respective first fastening opening upon insertion of the pair of connector tabs into the second tube; and
a plurality of fastener bolts, each fastener bolt being insertable through a respective first fastening hole and threadedly insertable into an associated second fastening hole for removably attaching the second tube to the first tube.
