Schlage ALX50P Spa 643E Grade 2 Cylindrical Lock

Product Description

The SCHLAGE ALX50P SPA 643E is a Grade 2 office cylindrical lock designed for commercial and light-commercial door hardware applications. It features a Sparta lever handle and a conventional cylinder core, making it a straightforward keyed-entry solution for office and interior corridor doors. The lock ships with field-selectable Vandlgard protection, which allows the installer to configure anti-vandal resistance on site without special tools. The aged bronze (643E) finish provides a consistent aesthetic for facilities using that hardware standard. Installation is non-handed, so it fits left- or right-swing doors without modification.

This lock is suited for office environments requiring controlled access at interior doors, such as private offices, utility rooms, and storage areas. The Grade 2 rating positions it for moderate-traffic commercial applications where a full Grade 1 heavy-duty lock is not required. The Sparta lever trim and conventional cylinder make it compatible with standard keying systems used in commercial rekeying programs. Facilities managers, locksmiths, and commercial door hardware installers are the primary trades that specify and install this lock.

Installation Notes

Installation is performed by a licensed locksmith or qualified commercial door hardware technician. Verify door thickness and backset before installation, as cylindrical locks require a properly prepped bore and latch prep to seat correctly. Disengage any access control or electric strike power before servicing the door hardware. Follow the manufacturer's template and local building code requirements for fire-rated door assemblies where applicable.
