Schlage Lock Company ND series Cylindrical Locks

Beyond grade 1 performance is the hallmark of the mechanical and electrified ND series locks. These locks are put through extreme levels of testing and are proven to withstand 3,100 in-lb. of abusive lever torque-more than 2-1/2 times the grade 1 standard requirement. Offset lever pull testing up to 1,600 lbs. assures you of the lock’s superb resistance against pry bar attacks. More than strong, ND series is built to last and shows nearly zero droop or wobble after 16 million cycles. All ND series locks including electronic functions, ligature-resistant trims, and ground-breaking, high-visibility status indication trims use the common cylindrical ANSI 161L door preparation making them easily interchangeable. They are ideal for all new construction and retrofit applications where grade 1 strength and security are desired.
