4070 Deadlock
Where a long-throw maximum security deadlock cannot be accommodated, the smaller 4070 deadlock offers the longest practical throw for a conventionally projected bolt from a narrow stile. Operation is via a standard mortice cylinder or thumbturn with (modified cam) from either or both sides.
