Schlage ALX10 Lat 643E Passage Cylindrical Lock

Product Description

The SCHLAGE ALX10 LAT 643E is a Grade 2 passage cylindrical lock designed for interior doors where latching without locking is required. It features the Latitude lever style and ships in an Aged Bronze (643E) finish. The lock includes field-selectable Vandlgard protection, which allows the installer to activate forced-entry resistance without special tools or additional hardware. This is a non-keyed passage function, meaning no key cylinder is installed. Non-handed design means it installs on doors of any swing direction without modification. Typically installed by commercial locksmiths, general contractors, or experienced facilities maintenance technicians.

This lock suits interior passage applications in light commercial and residential settings - hallways, closets, conference rooms, and similar non-secured openings. The field-selectable Vandlgard feature makes it a practical choice for higher-traffic or abuse-prone environments where a standard passage function is needed but additional physical durability is a priority. The Aged Bronze finish coordinates with 643E-series hardware on the same installation.

Installation Notes

Installation is performed by a licensed locksmith, general contractor, or qualified facilities technician. Verify the door prep matches standard cylindrical lock boring dimensions before installation. Confirm the door is not under load and that any electric latch retraction or access control wiring in adjacent hardware is de-energized before working in the door frame. Follow local building codes for hardware grade requirements in commercial occupancies.
