Flexibility of traffic control and installation is offered by the 4900 series deadlatches. A reverse turn of the key while bolt is held retracted retains the bolt, to allow two-way traffic and exit-only at other times. Interchangeable, with stile modification, with any MS1850A or MS1850S deadbolt of same backset and faceplate shape. Also retrofits to existing 4500/4700 deadlatch preparations. 1-3/4" minimum door thickness required.
Finishes: 313-Dark Bronze, 335-Black
