Separate rules govern locks, garage doors and windows.

Frames, Jambs, Strikes and Hinges. ... A. Door jambs shall be installed with solid backing in such a manner that no voids exist between the strike side of the jamb and the frame opening for a vertical distance of six inches each side of the strike. ...

The strike plate for deadbolts on all wood framed doors shall be constructed of minimum 16 U.S. gauge steel, bronze, or brass and secured to the jamb by a minimum of two screws, which must penetrate at least three inches into solid backing beyond the surface to which the strike is attached.
