The Schlage 47267022 is the universal chassis assembly for the ALX Series Grade 2 cylindrical lock family. It's part number 7 in the ALX Series service manual trim diagrams and appears in the parts breakdown for every keyed and non-keyed locking function in the line. When a chassis wears out, cracks, or fails internally due to heavy use or forced entry, this is the OEM replacement that brings the lock back to factory spec without replacing the full unit.

The 47267022 is a universal fit across the ALX Series, which is the defining design advantage of the entire platform. A single chassis supports all cylinder applications and most functions, so locksmiths and facility technicians working across a multi-function installation don't need to stock multiple chassis variants.

Which Schlage ALX Models Use the 47267022 Chassis Assembly?

This chassis is the direct replacement for seven ALX Series functions. On the non-keyed side, it fits the ALX10S Passage Latch, the base function that lets both levers operate freely at all times, and the ALX40 Bath/Bedroom Privacy Lock, which uses push-button locking with a coin-turn outside. On the hospital privacy side, it fits the ALX44S Hospital Privacy Lock, which uses a push-button inside with an emergency turn-button override on the exterior.

For keyed functions, the 47267022 covers the ALX50 Entrance/Office Lock, the ALX53 Entrance Lock, the ALX70 Classroom Lock, and the ALX80 Storeroom Lock. Because the chassis is interchangeable across all these functions, a facility that runs ALX Series locks throughout a building can maintain a single chassis part on the shelf rather than stocking function-specific components.

What Makes the Schlage ALX Universal Chassis Different

The 47267022 chassis is the mechanical heart of a lock that Schlage redesigned from scratch in 2019. The patent-pending modular chassis design was built around one core idea: one chassis body supports all functions and all cylinder formats, including conventional, FSIC, and SFIC options. That wasn't possible with the earlier designs that required separate chassis configurations for different functions.

The chassis uses deep-drawn spindles with five points of lever engagement, which is significantly more contact surface than typical Grade 2 designs. Combined with Grade 1 compression springs, the result is near-zero lever droop and wobble even after extended cycling in high-traffic applications like K-12 schools, healthcare corridors, and commercial office buildings. The latchbolt is oil-impregnated stainless steel as standard, with a 1/2 inch throw on the spring latch functions and a dead latch option on the keyed functions.

The ALX Series parts are manufactured to close tolerances and are interchangeable between functions, which is confirmed in the official ALX Series service manual. Converting a function in the field, swapping from entrance to storeroom for example, only requires substituting the function-specific components while the 47267022 chassis stays in place.

Door Thickness and Compatibility

The ALX Series chassis fits standard door thicknesses of 1-3/8 to 1-3/4 inches (35mm to 44mm) without spacers, and it wraps correctly on 1-3/4 inch doors up to 0.060 inches thick. The standard rose diameter is 3-7/16 inches. All ALX Series lever designs are ADA Accessibility compliant. The chassis supports both 2-3/8 inch and 2-3/4 inch backset configurations with the appropriate latch assembly.
