The Schlage 03-234-8TR is the OEM Tubular Tactile Lever with factory preparation for Corbin Russwin Conventional Key-in-Lever (KIL) cylinders, for the Schlage AD Series, ALX Series, CO Series, and ND Series cylindrical locks, documented in four official Schlage Service Manuals: ALX, ND, AD, and CO Series. Per the SecurityParts.com product page, the 03-234-8TR "is supplied less cylinder for field installation of a compatible Corbin Russwin conventional KIL cylinder." Non-handed.

Tubular Tactile Profile in the Corbin KIL Prep Format

The 03-234-8TR uses the Tubular lever profile with tactile surface in the 03-234 Corbin Russwin KIL prep format. The Tubular lever has a uniform round cylindrical rod handle, maintaining 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 tactile safety feedback from any grip approach angle. Per the SecurityParts.com product page, the 03-234-8TR "accepts a Corbin Russwin conventional Key-in-Lever (KIL) cylinder for manual latch retraction" and is an "exterior replacement lever for compatible Schlage locks configured for Corbin Russwin conventional Key-in-Lever (KIL) cylinders."

Within the 03-234 Corbin KIL prep family, the 03-234-8TR joins the 03-234-8AT (Athens Tactile), 03-234-8RO (Rhodes Tactile), and 03-234-8SP (Sparta Tactile) as tactile levers prepared for Corbin Russwin KIL cylinders. All four cover the same series, are documented in the same four Service Manuals, and ship less cylinder. The Tubular profile is the only distinction of the 03-234-8TR within the family. When a facility uses Tubular levers as its established standard and the installed cylinder is a Corbin Russwin conventional KIL cylinder, the 03-234-8TR is the correct replacement lever.

Critical Ordering Note: 03-234-8TR vs 03-231-8TR

Both the 03-234-8TR and the 03-231-8TR (Tubular Tactile KIL Lever Less Cylinder) are tactile Tubular levers supplied less cylinder. The critical difference is the cylinder bore preparation. The 03-234-8TR is prepared for Corbin Russwin conventional KIL cylinders. The 03-231-8TR is prepared for standard Schlage KIL cylinders. Installing the wrong cylinder type into either lever bore will result in an incorrect fit. Confirm the cylinder type used in the installed lock before ordering.
