Schlage ND-Series Grade 1 Heavy Duty Omega Lever Lock



Details: Schlage ND-Series Grade 1 Heavy Duty Omega Lever Lock

ND Series offers a full breadth of commercial lock options with a suited combination of mechanical, electrified and electronic options. Beyond grade 1 performance is the hallmark of the mechanical and electrified locks. ND Series locks are tested 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 and ligature-resistant trim use the common cylindrical ANSI 161 door preparation making them easily interchangeable. They are ideal for all new construction and retrofit applications.
