Abstract
A box lintel includes an elongated, hollow metal form with a lower wall, integrally formed side walls extending upwardly therefrom, and integrally formed partial upper walls extending inwardly from the side walls. A method of fabricating a box lintel is also disclosed which includes the steps of providing an elongated flat sheet of metal and bending the flat sheet of metal into a hollow metal form with a lower wall, integrally formed side walls extending upwardly therefrom, and integrally formed partial upper walls extending inwardly from the side walls. The form is adapted to be positioned on upright masonry supports so as to span an opening and to be filled with grout/mortar and to receive one or more courses of masonry bricks on the upper walls.
