4710 and 4720ANSI Heavy Duty Deadlatches
Offers flexible traffic control and an excellent level of security (though
not the maximum security of the MS® Deadbolts), and is often used in conjunction with 7100 Series Electric Strikes to provide remote access control. The auxiliary bolt feature deadlocks the latch when the door is closed against the strike. Maximum operational door gap is 5mm. Operates using Mortice Cylinder, Thumbturn (both with MS® cam) or 4591 Paddle Handle (with 4580 cam plug). The latch is interchangeable without stile modification with the MS®1850S Deadlock. To operate “Bolt Holdback” feature, push in bolt and secure by reverse turn of the key. Latchbolt reversible; supplied non-handed unless specified.

When used in emergency exit applications with a 4591 Paddle Handle, the assembly must use the 8460 Ramped Jaw Strike in order to conform to BS EN 179+A1: 2001.
