on a line 90 degrees from jamb perpendicular to frame head.
2.Alignment: Plus or minus 1/16 inch (1.6 mm), measured at jambs on a
horizontal line parallel to plane of wall.
3.Twist: Plus or minus 1/16 inch (1.6 mm), measured at opposite face
corners of jambs on parallel lines, and perpendicular to plane of wall.
4.Plumbness: Plus or minus 1/16 inch (1.6 mm), measured at jambs on a
perpendicular line from head to floor.

fastened in place; comply with Drawings and manufacturer's written
instructions.
B.Hollow Metal Frames: Install hollow metal frames of size and profile indicated.
