Original Part# 03-066-8SP. Available (3-4 weeks).

Sparta Tactile Profile in the Corbin Russwin J-CO6 Format

The 03-266-8SP uses the Sparta lever profile with a tactile surface in the 03-266 Corbin Russwin LFIC J-CO6 format. Per the SecurityParts.com FAQ: "The Schlage 03-266-8SP is a genuine OEM Sparta tactile exterior lever for Schlage ND, ALX, CO and D Series cylindrical locksets." The FAQ also confirms: "It is designed to accept a Corbin Russwin Full Size Interchangeable Core (FSIC) J-CO6." The tactile surface provides safety feedback by touch for hazardous area door identification where the Corbin Russwin J-CO6 core and the tactile designation are both specified at the outside trim position.

The 03-266-8SP, 03-266-8AT (Athens Tactile), and 03-266-8RO (Rhodes Tactile) are all tactile levers in the same 03-266 Corbin Russwin J-CO6 format. All three 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 03-266-8SP uses the Sparta design. When a building uses Sparta levers as its established standard and the installed core is a Corbin Russwin J-CO6 LFIC with the tactile designation required, the 03-266-8SP is the correct lever.

Corbin Russwin J-CO6 vs J-CO7: Selecting the Correct 03-266 vs 03-235 Family

The 03-266 prefix covers Corbin Russwin LFIC J-CO6 (6-pin) levers. The 03-235 prefix covers Corbin Russwin FSIC J-CO7 (7-pin) levers. Both are Corbin Russwin interchangeable core formats but with different pin counts and keyway designations. A J-CO6 core will not fit a 03-235 (J-CO7) lever, and a J-CO7 core will not fit a 03-266 (J-CO6) lever. Confirm the keyway designation stamped on the installed Corbin Russwin core before selecting between the 03-235 and 03-266 lever families.
