The SCHLAGE ND98PD RHO 613 is a Grade 1 cylindrical lock engineered for classroom security applications requiring 180-degree lockdown capability. It features a Rhodes lever handle and a conventional cylinder, finished in dark oxidized satin bronze oil rubbed (finish code 613). The non-handed design simplifies ordering and installation, fitting both left- and right-swing doors without modification. This lock is built to ANSI/BHMA Grade 1 standards, making it suitable for high-traffic institutional environments where reliable, fast lockdown response is a priority for security personnel and facility managers.
This lock is intended for classroom and institutional door applications where exterior lockdown from the corridor is required. The 180-degree lockdown function allows the door to be secured from the outside using a key, preventing entry while allowing free egress from the inside. It is typically installed in K-12 schools, universities, government buildings, and other facilities following current life safety and security codes. Licensed locksmiths, door hardware specialists, and facilities maintenance professionals handle installation.
Designed as an OEM-style cylindrical lock replacement or new-installation unit for Grade 1 commercial and institutional door applications requiring classroom security lockdown function.
Installation should be performed by a licensed locksmith or qualified door hardware technician familiar with ANSI cylindrical lock prep standards. Verify the door prep (latch backset, cross bore, and strike) matches the lock specifications before installation. Ensure the door and frame are properly aligned and that all existing hardware is removed and the door is secured in place before beginning work. Consult applicable building and life safety codes, including local fire and egress requirements, before finalizing the lockdown function configuration.
