A square tubular steel frame extends between inner and outer concrete footing form walls and prevents the inner and outer form walls from bowing inwardly and causing an undesirable narrow footing width, or bowing outwardly and causing a form blowout. The steel frame is adjustable in width to accommodate the narrowest to the widest footings. A lower bracket supports the bottom of the form, and is adjustable in height. Each end of the frame is replaceable to accommodate a single form thickness, or to accommodate overlapping forms. The frame is reusable, easy to set up, and simple to take down and move to the next job, and is safe to use.
