Grade 1 is just the beginning

Schlage® is pleased to introduce the redesigned ND Series Grade 1 cylindrical lock. Already exceeding BHMA Grade 1 standards, the redesigned ND uses new springcages, levers and latches to take strength, performance and reliability to an all-new level.

Improved strength and security

• No access with minimum 3,100 in-lbs of lever torque (2.6x BHMA, for general abuse)
• No access with minimum 1,600 lbs of offset lever pull (8x BHMA, for pry-bar attacks)
• No access with minimum 100 vertical impacts (20x BHMA, for sledgehammer attacks)

• Near-zero droop and wobble beyond 16 million cycles (after 16x BHMA) - without the use of set screws or O-rings
• Latch retraction with up to 200 pound preload (4x BHMA) for confident operation in warped and preloaded doors

• Cast steel spindle construction exceeding 16 million cycles
• Withstood aggressive Schlage development testing including lever-snap and abusive cycling
