Schlage ND80BDEU Rho 622 Electrified Cylindrical Lock

Product Description

The SCHLAGE ND80BDEU RHO 622 is a Grade 1 electrified cylindrical lock designed for storeroom function in commercial access control applications. It operates on 12-24 volts DC and is configured fail secure, meaning the latch remains locked when power is interrupted. The Rhodes lever handle and flat black coated finish provide a clean, professional appearance suited to commercial interiors. A 2-3/4 inch backset accommodates standard commercial door preparations. The SFIC prep less core configuration allows the installer to supply the appropriate small-format interchangeable core at the time of installation.

This lock is intended for commercial doors where controlled entry is required. Storeroom function keeps the outside lever locked at all times, requiring a credential or electric release to allow entry, while the inside lever remains free for egress. It is typically installed by licensed locksmiths or commercial door hardware technicians on hollow metal or wood doors in office, institutional, or light industrial environments where access control integration is part of the project scope.
