Schlage ALX50B BRK Grade 2 Office Cylindrical Lock with Field Selectable Vandlgard, Boardwalk Lever, SFIC Less Core

The Schlage ALX50B BRK is a Grade 2 office cylindrical lock with the Boardwalk lever, field-selectable Vandlgard, and a small format interchangeable core (SFIC) housing supplied less core. It's the office/entrance function (ANSI F82) in Schlage's modular ALX Series, built for the doors where someone inside needs simple push-button control over who gets in, offices, conference rooms, suites, and break rooms. As a Schlage Grade 2 office cylindrical lock, it pairs the convenience of push-button locking with the durability and field flexibility that make the ALX a smart pick across a whole building.

How the office function works

The office function (ANSI F82) is specific, and understanding it is what helps you spec it correctly. There's a key cylinder on the outside and a push button on the inside. Press the inside push button and the outside lever locks, so people in the room control entry without a key. To get back in from the corridor, you use the key outside, and from inside the lever is always free for immediate egress, so no one is ever trapped. Rotating the inside lever also releases the button. That push-button setup is exactly what an office door wants: staff lock up quickly from inside for privacy or a meeting, the door still opens instantly from within, and a keyholder can always get in from outside.

That's the difference from the other ALX functions. Where the storeroom lock stays locked by default and the classroom locks only by key from the corridor, the office function gives the occupant push-button control, which is the right behavior for an everyday office or conference room door.

Field-selectable Vandlgard and the SFIC core

Two features make this Schlage Grade 2 office cylindrical lock more flexible than a standard one. Field-selectable Vandlgard lets the outside lever rotate freely when locked, so wrenching on it doesn't damage the chassis, and you can switch Vandlgard on or off in the field, so one lock covers a high-abuse door and a normal one. The SFIC housing accepts a small format interchangeable core, which means it drops into an existing small-format key system and can be rekeyed in seconds by swapping the core. This one ships less core, so you supply the SFIC core that matches your keying.

Why specify the Schlage ALX Series

The ALX exists to solve a budgeting reality: you want Grade 1 security on the critical doors but can't justify it everywhere. The ALX is a true Grade 2 lock that operationally and visually suites with Schlage's Grade 1 ND Series, so you can run AND where demand is highest and ALX everywhere else while keeping a consistent look building-wide. The modular chassis is the long-term payoff, because when a room changes use you can reconfigure the lock function in the field instead of buying a new lock, which saves real money over a building's life. The SFIC option here also lets the office locks join the same interchangeable-core key system as the rest of the facility.

One thing to confirm before ordering: this is the SFIC less-core version, so you'll need a compatible small format core, and the office function (push button inside) is specific, so make sure that's the behavior your door needs rather than a storeroom or classroom function.
