A Hollow Metal masonry frame is designed to meet the specific requirements of masonry wall, which can include tile, stone, brick, or concrete. In this type of frame installation, the masonry wall is longer than the frame depth. To ensure a proper fit, the frame should be installed flush against one side of the wall – or butted up against the wall. The installation process for this application involves the use of anchors and dynabolts. The rough opening needed is the nominal door width + 4-1/2” and nominal door height + 2-1/4”. For example, a 3’0” (36″) x 6’8” (80″) door would need a rough opening of 3’4-1/2” (40-1/2″) x 6’10-1/4″ (82-1/4″).
