ABSTRACT:
A fluorescent luminaire lens frame is described wherein the frame is formed from a U shaped element, and a cross bar. Each of the two elements are formed from single piece sheet metal blanks. The frame includes hinge elements on the free ends of the U extending beyond the cross bar that may be coupled to a luminaire housing. The frame joints are also structured with abutting and capturing structures to prevent rotation of the sides away from about a right angle.
