In size, but not exact for reasons unbeknownst to me! The first 3 I think are maybe just COLD AIR RETURN COVERS as they DO NOT HAVE adjustable air flow panels on the back side. The fourth register does feature the adjustable air flow panel on the back.
The first two feature what some refer to as the Sunburst pattern. They also fit with Art Deco Decor. What you see is what you get. 13 1/8" wide and 15 1/4" tall and approx. Screw holes are 12 apart.
Register 2 (has more paint on the backside). 12 7/8" wide and 14 5/8" tall and approx.Register 3 also has a sunburst type pattern but the diamond border is larger than on #1 and #2. Register 4 has a diamond pattern and features the adjustable air flow vent on the back. (i will obtain exact measurements of registers 3 and 4 soon). I will package these with care!
