Schlage ND75PD - Heavy Duty Classroom Security Lock

The ND mechanical lock, along with being Schlage’s best selling mechanical lock, is the foundation for both the wired electrified and NDE wireless electronic lock. Not only did Schlage invent the cylindrical lock, but we continue to make it better with capabilities such as:

Unparalleled strength - the lock prevents access even when subjected to torque loads up to 3,100 in-lbs (2.6x BHMA1 ), withstands pry bar attacks of 1,600 lbs (8x BHMA requirements1 ), and withstands 100 hammer blows (20x BHMA requirements1, 2)

Exceptional durability - cycle tested to over 16M cycles (16x BHMA requirements1 ) with near zero droop or wobble - without the use of set screws or O-rings

Improved feel - improved strength and durability are more than numbers, you can actually feel it in the lock

Improved installation - installation is even easier than before (and withoutany set screws or O-rings)

All this is in addition to what you know and expect with the Schlage ND: 31 mechanical functions (plus wired electrified and wireless electronic) to meet the needs of any application; nine lever designs that suite with otherSchlage locks and Von Duprin exit devices; renowned sales, customer and technical support.

Classroom Security Lock

• Key in either lever locks or unlocks outside lever.

Applications

The Schlage ND is extremely versatile and is regularly used in healthcare, education, government, office, retail and other commercial applications.

With 31 mechanical functions, the ND's range spans from the simple (non-locking passage) to complex (double-cylinder security) to specialized (school time-out lock).

Because the ND uses an ANSI 161 door prep, commonly used across cylindrical locks, it is ideal for both new construction and retrofit applications.
