This is side component 1, it will attach to the main component to form a + shape. We designed the joists this way to fit the plywood board, which is 4' x 8'. We can do the floor with three boards this way. Using the least amount of plywood. These are about 2' 10" by 4', so they will make a 9' 7 7/8" span at right angles to the main component.
