a wall cladding section;
a plaster support section connected to the wall cladding section at a first edge, wherein a plurality of first opening and a plurality of second openings are formed through the plaster support section, and the plurality of first openings are closer to the first edge than the plurality of second openings;
an end ventilation section connected to the plaster support section at a second edge, wherein a plurality of third openings are formed through the end ventilation section; and
a guard and gauge section connected to the end ventilation section at a third edge, wherein a tip of the guard and gauge section faces the first edge, and a gap is formed between the tip of the guard and gauge section and the first edge.
2. The multi-purpose screed device of claim 1 , wherein the wall cladding section and the guard and gauge section are substantially co-planar.
3. The multi-purpose screed device of claim 2 , wherein the end ventilation section is substantially perpendicular to the wall cladding section.
4. The multi-purpose screed device of claim 1 , wherein the plurality of first openings are formed along the first edge.
5. The multi-purpose screed device of claim 4 , wherein the plurality of second openings are formed along a central line between the second edge and third edge.
6. The multi-purpose screed device of claim 1 , wherein the wall cladding section, the plaster supporting section, the end ventilation section, and the guard and gauge section are formed by bending a sheet material along the first edge, the second edge, and the third edge.
7. The multi-purpose screed device of claim 6 , wherein the wall cladding section and the plaster supporting section form an angle greater than 90 degrees.
8. The multi-purpose screed device of claim 7 , wherein the wall cladding section and the plaster supporting section form an angle in a range between 110 degrees and 130 degrees.
9. The multi-purpose screed device of claim 1 , wherein the plaster support section, the end ventilation section and the guard and gauge section enclose a transition volume, and the guard and gauge section prevents any collected water in the transition volume flowing towards a building structure.
10. The multi-purpose screed device of claim 9 , wherein the plaster support section is configured to attach both an upper portion and a lower portion of an exterior wall, when the plaster support section is attached to the upper portion of the exterior wall, the guard and gauge section is positioned to receive a clip-on cover.
11. The multi-purpose screed device of claim 1 , wherein the guard and gauge section is sized to function as an alignment gauge during installation.
12. A multi-purpose screed device, comprising:
an elongated body having a cross section profile comprising:
a first section;
a second section connected to the first section;
a third section connected to the second section; and
a fourth section connected to the third section, wherein the second, third and fourth section enclosing an inner volume, a gap exists between the second section and the fourth section,
wherein the first section and the fourth section are coplanar, and the gap is located between a tip of the fourth section and an edge connecting the first and second sections,
wherein a plurality of first openings are formed through the second section along the edge connecting the first and second section, and a plurality of second openings are formed through the third sections.
13. The multi-purpose screed device of claim 12 , wherein the plurality of first openings and the plurality of second openings are staggered.
14. The multi-purpose screed device of claim 12 , wherein a width of the plurality of first openings is in a range between about 0.1 inch and about 0.3 inch.
15. The multi-purpose screed device of claim 12 , wherein the plurality of the first openings and the plurality of the second openings have the same pitch.
16. The multi-purpose screed device of claim 12 , wherein the first section and the second section form an angle in a range between 110 degrees and 130 degrees.
17. The multi-purpose screed device of claim 12 , wherein the second section includes a plurality of third openings formed through a central region of the second section.
18. The multi-purpose screed device of claim 17 , wherein the plurality of third openings are circular openings having a diameter in a range between about 0.2 inch and about 0.5 inch.
19. The multi-purpose screed device of claim 12 , wherein the plurality of first opening has a smaller pitch than the plurality of third openings.
20. The multi-purpose screed device of claim 12 , wherein the gap is greater than 0.2 inch.
