The Schlage 03-237-TLR is the OEM Tubular Lever factory prepared for the Medeco 6-pin Large Format Interchangeable Core (LFIC / J-MED), for the Schlage AD Series, CO Series, ALX Series, ND Series, and NDE Series cylindrical locks, documented in five official Schlage Service Manuals including the NDE Series. Per the SecurityParts.com product page: "It features the Tubular lever design and is supplied less core for compatible Schlage lock applications." The primary function is confirmed as "Houses Medeco 6-pin LFIC cores for manual latch retraction." Supplied less cylinder. Standard non-tactile Tubular lever with round cylindrical handle. Non-handed.

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

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

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

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

Tubular Profile in the Medeco LFIC Format

The Tubular lever uses a uniform round cylindrical rod handle that is visually distinct from all other designs in the Schlage ND and ALX Series lever catalog. Athens, Rhodes, Sparta, and Omega levers use shaped handles with profiles that vary along the shank. The Tubular lever maintains a consistent circular cross-section from the hub to the handle tip. In the 03-237 Medeco LFIC format, the round Tubular profile is combined with the LFIC lever housing that accepts only Medeco 6-pin LFIC cores. Per the SecurityParts.com product page, the 03-237-TLR is a "genuine OEM Tubular-style exterior replacement lever, less cylinder, engineered by Schlage to provide compatibility across premium mechanical and electronic platforms."

The Medeco LFIC format is confirmed as "uniquely milled to fit the distinct physical shell dimensions, depth tolerances, and locking lug paths of a Medeco LFIC cylinder casing." Standard Schlage KIL cylinders or Schlage full-size interchangeable cores cannot be installed in this lever. A compatible Medeco 6-pin LFIC (J-MED) core must be sourced separately.

Choosing Between Tubular and Other 03-237 Lever Designs

The 03-237-TLR is the last of four standard non-tactile lever designs in the 03-237 Medeco LFIC family alongside the 03-237-ATH (Athens), 03-237-RHO (Rhodes), and 03-237-SPA (Sparta). All four share the same price, the same five-series coverage including NDE, and the same two-legacy-number structure. The Tubular profile is the only distinction of the 03-237-TLR. When a facility uses Tubular levers as its established profile standard and the installed core is a Medeco LFIC, the 03-237-TLR is the correct replacement lever to maintain visual consistency throughout the installation.

Five-Series Coverage and Finishes

The 03-237-TLR is compatible with Schlage AD Series, CO Series, ALX Series, ND Series, and NDE Series, as confirmed on the SecurityParts.com product page. Finish must be specified at time of order. Contact SecurityParts.com for current finish availability. The Medeco 6-pin LFIC core is not included and must be ordered separately.
