Product Summary

The 4510 Series Standard Duty Deadlatch offers flexibility of traffic control during and after business hours. A reverse turn of the key while the bolt is held retracted retains the bolt to allow two-way traffic for healthcare, financial institutions, retail, and other applications that require free entrance at certain times and exit-only at other times. Interchangeable, without stile modification, with any MS1850S Deadlock of same backset and faceplate shape. They do not, however, provide the same maximum security level as the MS®Deadlock.


Turn key or operate handle or paddle to retract spring-loaded latchbolt. To holdbolt retracted, push it in and secure by reverse turn of key. Lock accepts any standard mortise cylinder with MS® cam, available separately. 


  • Cylinder Backset: 7/8″, 31/32″, 1-1/8″ or 1-1/2″
  • Case: Steel with corrosion-resistant plating. Measures 1″ x 5-13/16″ x depth. Depth varies by backset.
  • Bolt Holdback: While bolt is held fully retracted, a reverse turn of the key retains the bolt, allowing the door to be free swinging
  • Latchbolt: All metal with hardened steel internal pins. Handing is reversible without special tools. Measures 1/2″ x 1″ x 1/2″ throw
  • Auxiliary Bolt: All metal. Deadlocks latchbolt to prevent “loiding” or case-knife entry
  • Faceplate: Measures 1″ x 6-7/8″ (flat faceplate)
  • Strike: 4902-01 for flat jamb where door closes flush or nearly flush or 4901-01 (longer strike) to cover slot strike of MS lock
  • Standard Package: Individually boxed with strike and mounting screws. Cylinder, paddle, handle available separately.
