Product Overview
Schlage ND98PD RHO Grade 1 Vandlgard Classroom Security Lock, Rhodes Lever, Standard Cylinder
Regarded as one of the world’s strongest cylindrical locksets, ND Series locks have been the most popular Schlage product ever since Walter Schlage invented the cylindrical lock in 1920. The ND Series is ANSI/BHMA Grade 1 certified and performs beyond the Grade 1 standards. The Schlage ND is extremely versatile and is regularly used in healthcare, education, government, office, retail, and other commercial applications. Because the ND uses an ANSI 161 door prep, commonly used across cylindrical locks, it is ideal for both new construction and retrofit applications.
ND98 Vandlgard classroom security lock (180-degree lockdown): Lever with key cylinder both sides; deadlatch. In unlocked state latch is retracted by either lever. Outside lever is made inoperative by rotating key in either lever 180 degrees counter-clockwise and returning to start position; Vandlgard allows outside lever to rotate freely when locked. Unlock outside lever by rotating key 180 degrees clockwise in either lever and returning to start position. Inside lever always free for immediate egress
Locks ordered in 626 finish come standard with instruction rose (47342586) identifying key rotation direction for rapid lockdown. Other finishes receive a standard rose.
Vandlgard™ trim is specifically designed for highly abusive environments. The outside lever rotates freely up and down when locked, limiting the ability of vandals to apply excessive force to the chassis.

- Withstands 3,100 in-lb. of abusive lever torque, as well as 1,600 lbs. of offset lever pull for protection against pry bar attacks
