Per the SecurityParts.com product page: "Accommodates Corbin Russwin 6-pin LFIC (J-CO6) core for manual latch retraction with built-in tactile safety grip." Supplied less core. Non-handed. Original Part# 03-066-8TR. Available (3-4 weeks).

Tubular Tactile Profile in the Corbin Russwin J-CO6 Format

The 03-266-8TR is the fourth and final tactile lever design in the 03-266 Corbin Russwin LFIC J-CO6 family, alongside the 03-266-8AT (Athens Tactile), 03-266-8RO (Rhodes Tactile), and 03-266-8SP (Sparta Tactile). All four are Available (3-4 weeks) at the same price, all supply less core, and all are documented in four Service Manuals covering ALX, ND, AD, and CO Series. The only difference is the lever profile. The 03-266-8TR uses the Tubular design: a uniform round cylindrical rod handle that is visually distinct from all other lever profiles in the Schlage ND and ALX Series catalog. 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 FAQ: "The Schlage 03-266-8TR is a genuine OEM tubular tactile exterior lever for Schlage J-Series cylindrical locks." The FAQ also confirms: "It is designed to accept a Corbin Russwin FSIC J-CO6 interchangeable core." A compatible Corbin Russwin J-CO6 FSIC core must be sourced separately. The core is not included.

When to Specify the 03-266-8TR Over the 03-235-8TR

Both the 03-266-8TR and the 03-235-8TR (Tubular Tactile Lever, Corbin Russwin FSIC J-CO7) are tactile Tubular levers for Corbin Russwin interchangeable core applications. The difference is the pin count and keyway. The 03-266-8TR accepts a J-CO6 (6-pin) core. The 03-235-8TR accepts a J-CO7 (7-pin) core. Confirm the keyway designation stamped on the installed Corbin Russwin core before ordering to ensure the correct lever format is selected. Installing a J-CO7 core into a 03-266-8TR bore, or a J-CO6 core into a 03-235-8TR bore, will result in an incorrect fit.
