Abstract: A framing member for use in a bleed sign construction assembly, the construction assembly including a projecting mounting surface and at least one construction light fixture arrayed proximate to the projecting mounting surface which is encased within a light permeable covering material. A substantially elongate and joinable member includes a body with a selected width and height in cross section and a longitudinally extending channel which reveals an interior cavity of the body. A first flange extends longitudinally from along a first side of the body and secures to the mounting surface to arrange the body at a spaced distance therefrom. A second flange extends longitudinally from along a second and opposite side of the body terminates along a remote extending edge. A plurality of the framing members are connected in end to end fashion to form a closed perimeter and the covering material is anchored within the interconnected channels and drawn across the framing members.

Abstract: A sign box joining device for slidable engaging and interlocking with at least one extrusion member. The joining device having an elongate, flat, top wall having downwardly extending side walls at opposite sides of the top wall and inwardly extending bottom wall flanges at bottom ends of the downwardly extending side walls. The extrusion member includes an elongate, flat, bottom wall having upwardly extending side walls at opposite sides of the bottom wall, one upwardly extending side wall having an inwardly extending top wall and the other upwardly extending side wall having and outwardly extending top wall. The joining device slidably engages and interlocks the pair of extrusion members when a portion of the top wall is in contact with a portion of the inwardly extending top wall of both extrusion members.
