Red Seal Carpenter Practice Exam

When installing a steel door frame in a masonry wall, the first step is to insert the masonry anchors. This is because the masonry anchors are used to secure the frame to the wall, providing a stable base for further installation. Plumb the jamb on the hinge side, level the head jamb, and fasten the jamb to the floor are all important steps in the installation process, but they can only be completed after the masonry anchors are in place. Therefore, these options are incorrect as they are not the first procedure in installing a steel door frame in a masonry wall.
