Features and Benefits At-a-Glance

The Schlage ND Series Grade 1 cylindrical lock:

  • Significantly exceeds ANSI/BHMA Grade 1 requirements.
  • Ensures zero access with a minimum 3,100 in-lb. abusive lever torque, equivalent to over 690 pounds applied to the end of a four and a half-inch lever, 2.6 times over the BHMA requirement.
  • Ensures zero access with a minimum 1,600 pounds offset lever pull for protection against pry bar attacks, eight times over the BHMA requirement.
  • Offers five points of engagement to provide nearly zero droop and wobble after 16 million cycles, 16 times over the BHMA requirement (without use of set screws or o-rings).
  • Offers high security locking when used with Primus XP UL 437 listed cylinders.


Function Availability and Convenience

  • Twenty-four (24)/four electrified functions (with custom functions available)
  • Multiple key systems available (open, patented and restricted)
  • Four electrified auto-detection functions for 12/24V DC operation, allowing for elimination of heated levers via maximum current draws of 0.4 amps and 0.1 amps holding current
  • Indicator roses for classroom applications
  • Three spring cage sets support all Schlage plus eight competitive cylinder formats


Aesthetics

  • Nine lever and four rose designs
  • Ten (10) available finishes
  • Perfectly suited to Schlage ALX Series Grade 2 locks
  • Suites with Von Duprin exit devices and other Schlage products


Options

Vandlgard option lets the lever freely rotate up and down when locked, shielding the chassis from excessive force on the lever to prevent vandalism (available on most keyed functions).

When it comes to certifications, Schlage has you covered there as well, what with the ND Series being tested and certified under ANSI/BHMA A156.2 Series 4000 Grade 1, in addition to UL/cUL listed with all locks meeting ADA requirements and being Florida Building Code and Miami Dade hurricane requirements compliant. Furthermore, all levers with a return to door of one-half-inch or less comply with California Referenced Standards Code, and all products in the ND Series meet the Buy American Act.
