Schlage 03-231-8TR is a genuine OEM tactile Tubular-style exterior lever less core for compatible Schlage AD, ALX, CO, and ND Series commercial locks with Schlage KIL (Key-in-Lever) cylinders. Also referenced as 03-031-8TR.
The Schlage 03-231-8TR is the OEM Tactile Tubular Lever Less Core for the Schlage ALX Series, ND Series, CO Series, and AD Series cylindrical locks, documented in the official Schlage ALX, ND, AD, and CO Series Service Manuals. It is the Tubular lever profile with tactile surface in the open cylinder KIL (Key-in-Lever) format. It is supplied less core, allowing installation with a compatible Schlage KIL cylinder. Non-handed. The legacy part number is 03-031-8TR. Ten finishes are available including 626AM. Available (3-4 weeks).
Tubular Tactile Profile in the KIL Lever Format
Per the SecurityParts.com product page, the 03-231-8TR "accommodates key-in-lever cylinder insertion, provides manual latch retraction, and features tactile safety feedback." It is classified as an Open Cylinder Tactile Lever. The open cylinder bore in the lever hub accepts a standard Schlage KIL conventional cylinder. The lever ships without the cylinder installed. A compatible KIL cylinder must be sourced separately and installed at the outside trim position.
The Tubular lever uses a round cylindrical rod handle profile, which is visually distinct from every other lever design in the Schlage ND and ALX Series catalog. The Athens, Rhodes, Sparta, and Omega designs all use shaped handles with cross-sections that vary along the shank. The Tubular lever maintains a uniform circular cross-section from the hub to the handle tip. The tactile surface on the 03-231-8TR wraps around this round profile and provides safety feedback by touch for hazardous area door identification where tactile levers are required at outside trim positions.
03-231-8TR vs Other Tactile KIL Levers in the 03-231 Family
The Schlage 03-231 KIL lever family includes four tactile designs: Athens (03-231-8AT), Rhodes (03-231-8RO), Sparta (03-231-8SP), and Tubular (03-231-8TR). All four ship less core, cover the same range of keyed ND Series and ALX Series functions, and accept a KIL cylinder. The only difference between them is the lever profile design. The 03-231-8TR is the correct choice when the Tubular profile is the established lever standard in the building and specific doors at that installation require the tactile designation.
