## Abstract

A dry wall extrusion grille comprising a frame, a linear bar grille, indented slots, and a flexible mounting flange.

## Claims

### Claim 1

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;
indented slots;
through holes;
a 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;
wherein said extrusion grille is used with a fixed core, a core welded directly to said frame, or a removable core.

### Claim 2 (depends on 1)

The extrusion grille of claim 1 wherein said flexible mounting flange is fastened to a wall or ceiling with said through holes being pre-perforated.

### Claim 3 (depends on 2)

The extrusion grille of claim 2 further comprising dry wall screws.

### Claim 4 (depends on 3)

The extrusion grille of claim 3 wherein said frame is installed with said dry wall screws before plaster or a joint compound is applied.

### Claim 5 (depends on 1)

The extrusion grille of claim 1 wherein said frame is constructed of mitered pieces.

### Claim 6 (depends on 5)

The extrusion grille of claim 5 wherein said mitered pieces are welded together.

### Claim 7 (depends on 1)

The extrusion grille of claim 1 wherein said extrusion grille is a fully welded construction.

### Claim 8 (depends on 1)

The extrusion grille of claim 1 wherein an inside of said extrusion grille frame extends about ¾″ deep into an opening so that said extrusion grille is installed in a wall board or plaster ranging from about ¼″ thru about ¾″ thick.

### Claim 9 (depends on 1)

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.

### Claim 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 ¾″.

### Claim 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.

### Claim 12 (depends on 11)

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

### Claim 13 (depends on 11)

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

### Claim 14 (depends on 11)

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

### Claim 15 (depends on 14)

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.

### Claim 16 (depends on 11)

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