This is the openings for the front cabinets. there are 5 studs in the wall, one on each end, one in the center, and one on either side, which you can see. This gives me 4 compartments, about 7-1/2 inches wide (average) 30 inches tall, and 3.5 inch width of the studs. I painted the "closet interiors" completely around in a tan, latex acrylic.
