The bottom cill of the sides attaches to the corner bars in a similar way. Undo the nuts and bolts inserted in the gable end
assembly, move the cill under the corner bar so that the elongated hole in the vertical flange of the side cill lines up with the

corner bar is pushed right down into the angle of the cill. Do the same at the other 3 bottom corners.
