Schlage ALX53P Rho 643E Grade 2 Cylindrical Lock

Product Description

The SCHLAGE ALX53P RHO 643E is a Grade 2 entrance cylindrical lock designed for commercial and light commercial door hardware applications. It features a Rhodes lever handle with a conventional cylinder and ships in an Aged Bronze (643E) finish. The lock includes field-selectable Vandlgard, a ligature-resistant and vandal-resistant feature that allows the installer to enable or disable the function on-site without additional parts. This unit is non-handed, meaning it installs on doors swinging in either direction without modification. Licensed locksmiths, commercial door hardware installers, and general contractors are the typical trade professionals who specify and install this hardware.

This cylindrical lock is suited for entrance function applications in light commercial buildings, multi-family residential properties, office suites, and interior secured access points. The entrance function allows free egress from the inside while requiring a key or credential to enter from the outside. The non-handed design simplifies inventory management for contractors handling multiple door openings in a single project. The field-selectable Vandlgard feature is particularly useful in high-traffic or institutional settings where lever tampering is a concern.
