Abstract
A method and apparatus for constructing hollow metal frames having a grout filled interior is disclosed. An apparatus includes a substantially planar body having an upper and lower surface. The upper surface includes at least one grip. The lower surface includes a gasket and a number of protrusions. The protrusions are placed into holes on the hollow metal frame into which additional components such as hinges are to be added. Grout is added to the frame and allowed to harden. Once the grout is hardened, the grout guard is removed and air spaces are retained. Screws and other components are typically filled into the air spaces.
