Schlage ND78PD Rho 626 Classroom Security Cylindrical Lock

Product Description

The SCHLAGE ND78PD RHO 626 is a Grade 1 cylindrical lockset designed for classroom security applications requiring 180-degree lockdown capability. It features a Rhodes lever handle and a conventional keyed cylinder in a satin chrome finish. The lock is non-handed, meaning it installs on doors with either hand without modification. This unit is suited for commercial and institutional environments where rapid lockdown from inside the room is a code-driven requirement. Licensed locksmiths and commercial door hardware installers are the typical trade for this product.

This lockset is intended for classroom and institutional corridor doors in K-12 schools, universities, and similar facilities where life-safety lockdown procedures are in place. The 180-degree lockdown function allows the lock to be secured from inside the classroom without opening the door or exposing occupants to hallway conditions. The Rhodes lever profile and satin chrome finish suit standard commercial door hardware programs. Non-handed design simplifies inventory management for facilities with mixed door swing directions.
