Standard Duty Deadlatch, ANSI/BHMA Type E8231, Grade 1
FUNCTION: Flexibility of traffic control during and after business hours is offered by 4510 Series Deadlatches. A reverse turn of the key while bolt is held retracted retains the bolt, to allow two-way traffic for hospitals, banks stores and other buildings which require free entrance at certain times and exit-only at other times. Interchangeable, without stile modification, with any MS1850A or MS1850S deadbolt of the same backset and faceplate shape. (They do not, however, provide the same maximum security level as the MS Deadbolt.)

STRIKES: Standard strike furnished is the 4902-01 for flat jamb where door closes flush or nearly flush. Also available radius strikes, longer strikes, and long lip strikes for center hung doors.
