9. The extrusion grille of claim 1 wherein said extrusion grille is mounted, so that said entire frame and grille are flush to a wall providing a seamless installation.

10. A dry wall extrusion grille comprising: a frame; a linear bar grille located in said frame comprised of vanes and cross members that direct a flow of air; through holes located in a flexible mounting flange; indented slots; said flexible mounting flange located between a top and bottom edge of the frame extending outwardly from said frame; said indented slots defined as small recesses in said flexible mounting flange that receive plaster, joint compound or mud; said frame being extended to at least .

11. A dry wall extrusion grille comprising; a frame; a linear bar grille located in said frame comprised of vanes and cross members that direct a flow of air; through holes located in a flexible mounting flange; indented slots; said flexible mounting flange located between a top and bottom edge of the frame extending outwardly from said frame; said indented slots defined as small recesses in said flexible mounting flange that receive plaster, joint compound or mud; mounting strips attached to a bottom of said frame.

12. The extrusion grille of claim 11 wherein said mounting strips are attached to said frame via welding.

13. The extrusion grille of claim 11 wherein said mounting strips are made as an integral part of said frame in one piece extrusion.

14. The extrusion grille of claim 11 further comprising an attachment device for attaching said linear bar grille to said frame.

15. The extrusion grille of claim 14 wherein said attachment device includes mechanical fasteners, threaded inserts in said mounting strips to be used with mechanical fasteners, or a projection on the frame or said mounting strips for use with spring steel clips.

16. The extrusion grille of claim 11 further comprising angled edges to capture plaster or joint compound.

DETAILED DESCRIPTION OF THE INVENTION

(12) FIG. 1 shows the frame 10 comprising four mitered pieces 12, 14, 16 and 18, which are welded at 20, 22, 24, and 26. FIG. 2 shows the bottom view of frame 10 of FIG. 1.

(13) FIGS. 3 and 4 show the extrusion grille 30, which comprises a linear bar grille 32. The extrusion grille 30 has an aluminum profile 34, a flexible edge 36, that is used for fastening to a wall or ceiling with perforated through holes 40. The extrusion grille 30 further comprises indented slots 38 used to capture joint compound or plaster 42.

(14) Extrusion grille 30 further comprises a special angled edge 44 to create a step for a spackling knife to use as a straight edge. A common sheet rock screw 46 is threaded into the wall material.

(15) FIG. 5 shows the extrusion grille 30 having the linear bar grille, a standard sheet rock screw 46, and pre-perforated mounting through holes 48 that provide many mounting options to address multiple field conditions.

(16) FIG. 6 shows the extrusion grille 30 installed after the plaster or joint compound is applied. The frame 10 is installed with the sheet rock screw 46 before plaster or joint compound is applied.

(17) FIG. 7 shows a dry wall extrusion grille 100 having a flexible edge 102. The flexible edge 102 has indented slots 104 used to capture joint compound or plaster. The frame 106 is extended by the length 110 to assist in attaching dampers or filters. The frame 106 further comprises a thru-hole 108. In a preferred embodiment, the extended length 110 is extended more than down.

(18) FIG. 8 shows a dry wall extrusion grille 120 having a flexible edge 122. The flexible edge 122 has indented slots 124 used to capture joint compound or plaster. The frame 126 includes mounting strips 128 that are attached to the bottom of the frame 126 via welding or they can be made as an integral part of the frame 126 in a one piece extrusion.

(19) FIG. 9 shows a dry wall extrusion grille 140 having a flexible edge 142. The flexible edge 142 has indented slots 144 used to capture joint compound or plaster. The frame 146 includes mounting strips 148 that are attached to the bottom of the frame 146. Multiple methods of attaching the linear bar grille to the frame 146 with an attachment device 150, that can include mechanical fasteners, threaded inserts in the mounting strip 148 to be used with mechanical fasteners, a projection on the frame 146 or mounting strip 148 for use with spring steel clips.

(20) FIG. 10 shows the dry wall extrusion grille 160 having a flexible edge 162. The flexible edge has indented slots 163 used to capture joint compound or plaster.
