Schlage ND98PD Rho 626 Classroom Security Cylindrical Lock

Product Description

The SCHLAGE ND98PD RHO 626 is a Grade 1 cylindrical lockset designed for classroom security applications requiring 180-degree lockdown capability. It features the Rhodes lever handle and a conventional cylinder, finished in satin chrome (626). The non-handed design means it installs on doors of either hand without modification. Built to ANSI/BHMA Grade 1 standards, this lock is suited for institutional and commercial environments where rapid lockdown response and long-term durability are required. Locksmiths and commercial door hardware installers are the typical trades for this unit.

This lockset is intended for classroom and institutional door applications where a single-action exterior lockdown is required. The 180-degree lockdown function allows the door to be secured from inside the room without opening the door or using a key from the interior side, which meets the operational requirements of most school security protocols. It fits standard commercial cylindrical lock preps and is appropriate for interior corridor doors in K-12 schools, universities, and similar institutional facilities.

• ANSI/BHMA Grade 1 heavy-duty cylindrical lock construction for high-cycle institutional use

Compatibility

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with ANSI cylindrical lock prep dimensions. Verify the door prep (cross bore, face bore, and latch backset) matches the lock requirements before installation. Coordinate keying with the facility key control system prior to final installation. Consult applicable building and fire codes, including IBC and local authority requirements, regarding hardware function for means-of-egress doors.
