Sparta Tactile Lever with Corbin KIL Prep: What the 03-234 Format Requires

The 03-234 prefix identifies levers with factory preparation for Corbin Russwin Conventional KIL cylinders. The lever bore is machined specifically to accept a Corbin Russwin cylinder, not a standard Schlage KIL cylinder. This distinction matters at the ordering stage. Confirming the cylinder type installed in the lock before ordering is essential. If the installed lock uses a standard Schlage KIL cylinder, the 03-231-8SP (Sparta Tactile KIL Lever Less Cylinder) is the correct replacement. If the installed lock uses a Corbin Russwin conventional KIL cylinder, the 03-234-8SP is correct.

Per the SecurityParts.com product page, the 03-234-8SP is designed for "compatible Schlage AD, CO, ALX, and ND Series lock applications configured for Corbin Russwin conventional Key-in-Lever (KIL) cylinders." A compatible Corbin Russwin conventional KIL cylinder must be sourced separately and installed in the field.

Sparta Profile: Choosing Between 03-234-8SP, 03-234-8AT, and 03-234-8RO

The 03-234-8SP, 03-234-8AT (Athens Tactile), and 03-234-8RO (Rhodes Tactile) are all tactile levers in the same 03-234 Corbin KIL prep format. All three are factory prepared for Corbin Russwin KIL cylinders, ship less cylinder, are compatible with the same four series, and are documented in the same four Service Manuals. The only difference between them is the lever profile design. The 03-234-8SP uses the Sparta lever design. When a building project uses Sparta levers as its established profile standard and the cylinder requirement is a Corbin Russwin conventional KIL cylinder, the 03-234-8SP is the correct lever to maintain visual consistency while meeting the Corbin KIL cylinder preparation requirement.
