Per the SecurityParts.com product page: "Accommodates a Corbin Russwin 6-pin LFIC (J-CO6) cylinder core insertion and transmits mechanical handle rotation to execute manual latch retraction."

Three Legacy Part Numbers Replaced by the 03-266-TLR

The 03-266-TLR replaces three legacy part numbers, as confirmed on the SecurityParts.com product page under "Original Part#."

• 03-066-TLR: Original part number for cylindrical lock outside trim applications using the Tubular Corbin Russwin J-CO6 lever.
• 09-366-TLR: Original part number for mortise lock trim applications. The 09 prefix in the legacy Schlage system identified mortise trim levers.
• 03-366-TLR: Original part number for exit device outside trim applications.

Any maintenance record or specification referencing these three legacy numbers maps to the 03-266-TLR as the current OEM replacement, regardless of whether the original installation was on a cylindrical lock, mortise lock, or exit device.

Tubular Profile Completing the 03-266 Standard Lever Family

The 03-266-TLR completes the standard non-tactile 03-266 Corbin Russwin J-CO6 lever family alongside the 03-266-ATH (Athens), 03-266-RHO (Rhodes), and 03-266-SPA (Sparta). All four are In Stock at the same price, all ship less core, all carry three legacy part numbers covering cylindrical, mortise, and exit device applications, and all are documented in five Service Manuals including NDE Series. The only difference is the lever profile. The 03-266-TLR uses the Tubular design: a uniform round cylindrical rod handle that is visually distinct from all other profiles in the catalog. Per the FAQ: "The 03-266-TLR is supplied less core, so the Corbin Russwin FSIC must be purchased separately or reused from an existing lock."

Standard vs Tactile: 03-266-TLR vs 03-266-8TR

The 03-266-TLR is the standard non-tactile Tubular Corbin Russwin J-CO6 lever. The 03-266-8TR is the tactile version with a built-in tactile safety grip wrapping the round handle circumference. The 03-266-TLR is In Stock with five Service Manuals including NDE. The 03-266-8TR is Available (3-4 weeks) with four Service Manuals and no NDE coverage. Confirm the original installation specification before ordering to avoid installing a standard lever at a position that required the tactile designation.
