ABSTRACT:
An improved security strike plate assembly is provided. The assembly consists of a wrap-around security plate which normally includes an adjustable strike plate. The security plate extends around three sides of a wood lock-side jamb member to which it is mounted in order to enhance the impenetrability of the door by preventing splitting of the lock-side jamb and resultant dislocation of the strike plate and keeper during thrusts against the door. The strike plate is adjustable without removing the security plate to accommodate slight variations in the size or shape of the door or frame during seasonal or atmospheric changes.
