Corbin Russwin CL33905 NZD 626 Fail Secure Electrified Cylindrical Leverset with NZD Newport Lever, Satin Chrome, Less Core

Remote Locking and Unlocking with Proven CL3300 Series Cylindrical Lockset Technology

The Corbin Russwin CL33905 NZD 626 is a Grade 1 fail secure electrified cylindrical leverset from the CL33900 Series, engineered to provide remote locking and unlocking for high-security commercial applications. Featuring the NZD Newport lever design in a 626 Satin Chrome finish, this leverset operates on 12VAC/DC (hard wired, 250mA) and is designed for doors with a thickness range of 1-3/4" to 2" with a 2-3/4" backset. In fail secure mode, power off locks the outside lever while the inside lever remains always free, and the latchbolt can be retracted by key when power is off, ensuring life safety compliance at all times.
