Abstract
A door frame with and threshold for mounting optional latch strikes, lock strikes and blank covers in the same door frame. The door jamb includes cut-outs and a reinforcement with depressed center portions opposite the cut-outs for attaching matching strikes of optional latches and locks. The shapes of the cut-outs, reinforcement and matching strikes cooperate in a manner which allow the same door frame to be used with existing latches and locks. The improved threshold eliminates the failures of seals in vertical gap in current thresholds because of temperature changes and persons stepping on thresholds.
