Schlage ND53 Grade 1 Entrance Lever Lock

Schlage ND53 Grade 1 Entrance Lever Lock

The Schlage® ND family significantly exceeds BHMA Grade 1 requirements for cycle, lever torque, hammer blow, lever pull and other tests. This means confidence that the lock will last—whether the application calls for high abuse resistance or just operation over millions of cycles— without any degradation in performance.

The Schlage ND is extremely versatile and is regularly used in healthcare, education, government, office, retail and other commercial applications. Because the ND uses an ANSI 161 door prep, commonly used across cylindrical locks, it is ideal for both new construction and retrofit applications.
