The Schlage 03-235-8TR is the OEM Tubular Tactile Lever with factory preparation for Corbin Russwin Full-Size Interchangeable Core (FSIC/LFIC) J-CO7 7-pin cores, for the Schlage AD Series and CO Series cylindrical locks, documented in two official Schlage Service Manuals: AD Series and CO Series. Per the SecurityParts.com product page, the 03-235-8TR "is supplied less core, allowing installation with a compatible Corbin Russwin J-CO7 7-pin FSIC." The product type is confirmed as "Full Size Interchangeable Core (FSIC/LFIC) Lever Trim (Less Core)." The lever design is confirmed as "Tactile Tubular." Non-handed.

Three Legacy Part Numbers Replaced by the 03-235-8TR

The 03-235-8TR replaces three legacy part numbers, as confirmed on the SecurityParts.com product page under "Original Part#."

• 23854573: Original part number for cylindrical lock outside trim positions using the Tubular Corbin Russwin FSIC J-CO7 lever.
• 09-366-8TR: Original part number for mortise lock trim applications. The 09 prefix in the legacy Schlage system identified mortise trim levers.
• 03-366-8TR: Original part number for exit device outside trim applications.

All three installation types are served by the 03-235-8TR as the current OEM part number. Any maintenance record or specification referencing these three legacy numbers maps to the 03-235-8TR for current ordering.

Tubular Tactile Profile in the Corbin Russwin FSIC J-CO7 Format

The Tubular lever uses a uniform round cylindrical rod handle that maintains a consistent circular cross-section from the hub to the handle tip. The tactile surface wraps around the full circumference of the round handle, providing safety feedback from any grip approach angle. This makes the 03-235-8TR suitable for hazardous area door identification at outside trim positions where the Tubular profile is the facility standard and the installed core is a Corbin Russwin J-CO7 7-pin FSIC.

Within the 03-235 Corbin Russwin FSIC J-CO7 family, the 03-235-8TR shares its AD and CO Series coverage with the 03-235-8SP (Sparta Tactile). Both have two Service Manuals and the same FSIC/LFIC product type designation. The 03-235-8RO (Rhodes Tactile) in the same family covers a wider four-series range with four Service Manuals. When replacing a Tubular Corbin Russwin FSIC J-CO7 lever on an AD or CO Series lock, the 03-235-8TR is the correct part. Confirm the installed lever profile before ordering to ensure the correct design is selected.
