What the 03-237 Medeco LFIC Format Means

The 03-237 prefix identifies levers with factory preparation for the Medeco Large Format Interchangeable Core (LFIC). Per the SecurityParts.com FAQ for this product: "This lever is uniquely milled to fit the distinct physical shell dimensions, depth tolerances, and locking lug paths of a Medeco LFIC cylinder casing." The FAQ also confirms the Medeco LFIC keyway designation as "J-MED."

The LFIC format is distinct from both the FSIC (Full Size Interchangeable Core) and the SFIC (Small Format Interchangeable Core). The product type is confirmed as "Large Format Interchangeable Core (LFIC) Lever Trim (Less Cylinder)." A compatible Medeco 6-pin LFIC core must be sourced separately and installed in the field. Per the SecurityParts.com FAQ: "Can I install a standard Schlage Key-in-Lever (KIL) cylinder or a Schlage full-size core into this Athens lever? No. This lever is uniquely milled to fit the distinct physical shell dimensions, depth tolerances, and locking lug paths of a Medeco LFIC cylinder casing."

Two Legacy Part Numbers Replaced by the 03-237-ATH

The 03-237-ATH replaces two legacy part numbers, as confirmed on the SecurityParts.com product page under "Original Part#."

• 09-388-ATH: Original part number covering both cylindrical lock and mortise lock outside trim applications using the Athens Medeco LFIC lever.
• 03-388-ATH: Original part number for exit device outside trim applications.

Any maintenance record or specification referencing 09-388-ATH (cylindrical or mortise) or 03-388-ATH (exit device) maps to the 03-237-ATH as the current OEM replacement.

Five-Series Coverage Including NDE

It is documented in five Service Manuals: ND, AD, ALX, CO, and NDE Series. The NDE Series inclusion confirms the 03-237-ATH applies to NDE exit device outside trim applications configured for Medeco LFIC cores. Per the SecurityParts.com FAQ: "This premium OEM component features Schlage's universal architectural trim engineering, enabling it to fit seamlessly onto AD Series, CO Series, ALX Series, and ND Series chassis configurations."
