Tubular Corbin KIL Prep Lever: Standard vs Tactile

The 03-234-TLR is the standard non-tactile version of the Tubular Corbin KIL prep lever. The 03-234-8TR (Tubular Tactile Lever, Corbin KIL Prep) is the tactile version with a raised texture applied around the round handle circumference for hazardous area door identification. Both are prepared for Corbin Russwin conventional KIL cylinders and ship less cylinder. Key differences are the handle surface and the NDE Series coverage. The 03-234-TLR includes NDE Series (5 Service Manuals). The 03-234-8TR does not include NDE (4 Service Manuals). When replacing a standard Tubular Corbin KIL lever, verify the original was not specified with the tactile designation before ordering the 03-234-TLR.

03-234-TLR vs 03-231-TLR: Choosing the Correct Format

Both the 03-234-TLR and the 03-231-TLR (Tubular Lever Less Cylinder) are standard Tubular levers that ship less cylinder. The difference is the cylinder bore preparation. The 03-234-TLR is prepared for Corbin Russwin conventional KIL cylinders. The 03-231-TLR is prepared for standard Schlage KIL cylinders. Confirm the cylinder type installed in the lock before ordering. Installing a Schlage KIL cylinder into a 03-234-TLR bore or a Corbin Russwin cylinder into a 03-231-TLR bore will result in an incorrect fit.

NDE Series and Availability Note

The 03-234-TLR is documented in five Schlage Service Manuals including the NDE Series Parts and Diagrams Manual, as confirmed on the SecurityParts.com product page. This makes the 03-234-TLR suitable for NDE exit device outside trim applications configured for Corbin Russwin KIL cylinders. Availability is confirmed as Available (3-4 weeks) per the product page, which differs from the 03-234-RHO and 03-234-SPA standard Corbin KIL levers, both of which show In Stock.
