Schlage ND75PD RHO Grade 1 Classroom Security Lock, Rhodes Lever, Standard Cylinder

Regarded as one of the world’s strongest cylindrical locksets, ND Series locks have been the most popular Schlage product ever since Walter Schlage invented the cylindrical lock in 1920. The ND Series is ANSI/BHMA Grade 1 certified and performs beyond the Grade 1 standards. 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.
