  • Other Information

The ND Series has been redesigned to make it the strongest cylindrical lock Schlage has ever built

  • No access with minimum 3,100 in-lb abusive lever torque — the equivalent of over 690 lbs applied to the end of a 4 1⁄2" lever (2.6x BHMA requirements1)

  • No access with minimum 1,600 lbs offset lever pull for protection against pry bar attacks
    (8x BHMA requirements1)

  • No access with minimum 100 vertical impacts1,2 for protection against sledgehammer attacks (20x BHMA requirements1)

  • Near zero droop and wobble after 16M cycles (16x BHMA requirements1), without the use of set screws or O-rings

  • Latch retraction with 200lb preload for confident operation in warped and preloaded doors
    (4x BHMA requirements)

1.  Beyond grade 1 performance for ND locks with Schlage cylinders only (standard, FSIC & SFIC). Performance with non-Schlage cylinders will exceed BHMA grade 1 requirements but may be less than the performance of products with Schlage cylinders.

2.  Vertical impact testing stopped after 100 blows with no sign of failure or stress.
