Another great use of a cleat! Use glue and 1-5/8 in. drywall screws to hold together the boxes, then customize shelving for whatever you want to store. Make the width about 3/8 in. narrower than the cavity it fits in and use double-nutted 3/8 in. x 3-1/2 in. carriage bolts for the two pivot points.Two plywood cleats pivot on 3-in. screws to hold each drawer in place in the “tucked” position. But be careful to keep contents relatively light so you can safely open and close the drawers.
