4510 SeriesStandard Duty Deadlatch
510 Standard Duty Deadlatches provide flexible traffic control during and after business hours.
The 4510 Series Standard Duty Deadlatch offers flexibility of traffic control during and after business hours.

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.
