The 4512-45-221-313 from Adams Rite is a standard deadlatch with bevel faceplate and strike in dark bronze anodized. The 4512 series Deadlatch offers maximum flexibility of traffic control during and after business hours. A reverse turn of the key (while bolt is held fully retracted) retains the bolt allowing the door to be free swinging with two-way traffic for hospitals, banks, stores, and other buildings which require free entrance at certain times and exit-only at other times. It is easily interchangeable, without stile modification with any MS1850A or MS1850S Deadlock of same backset and faceplate shape. However, they do not provide the same maximum security level as the MS Deadlock and should not be considered an equivalent replacement.
