The Schlage 03-234-ATH is the Athens (ATH) lever assembly for the Schlage AD, ALX, CO, and ND Series cylindrical locks, configured with a Corbin Russwin conventional KIL (Key-In-Lever, L-CO6) cylinder housing, less core. Finish must be specified at time of order.
"Less core" means the lever assembly includes the Corbin Russwin KIL-format cylinder housing but not the plug or tumbler assembly. The facility provides and installs their own Corbin Russwin cylinder into the housing. This configuration is for buildings running Corbin Russwin key systems that want to install Schlage AD, ALX, CO, or ND locks while keeping all hardware operating on the existing Corbin Russwin master key system - without ordering or managing a separate set of Schlage cylinders.
Schlage Athens Lever: Design and ADA Compliance
The Athens (ATH) is one of the standard lever designs available across the Schlage ND and ALX Series product lines. Per the Schlage ND Series Data Sheet, standard levers are pressure cast zinc, plated to match the specified finish. Available finishes for the 03-234-ATH include 605, 606, 612, 613, 619, 622, 625, 626, and 643e.
All ND Series levers - including the Athens - comply with the Americans with Disabilities Act (ADA) and ICC A117.1 for Accessible and Usable Buildings. The ADA requires that operable hardware be usable with one hand without tight grasping, pinching, or twisting of the wrist, with a maximum activation force of 5 pounds (22.2N). The Athens lever meets this requirement in all finishes.
The 03-234-ATH lever is also available in three other designs using the same Corbin Russwin KIL cylinder housing: Rhodes (03-234-RHO), Sparta (03-234-SPA), and Tubular (03-234-TLR). If the installed lock uses Rhodes, Sparta, or Tubular lever style rather than Athens, order the corresponding suffix.
Corbin Russwin Conventional Cylinder: Why the "Less Core" Format
The Corbin Russwin KIL (L-CO6) is a 6-pin key-in-lever cylinder format. The conventional version uses a standard pin tumbler plug that is pinned in the field to the facility's key system - it is not an interchangeable core format. "Less core" in this context means the plug and pins are not included; the facility's locksmith provides and installs the correctly pinned Corbin Russwin cylinder into the housing.
This is the correct format for facilities that have an established Corbin Russwin conventional key system and are adding Schlage AD, ALX, CO, or ND locks to their inventory. The locks operate on Corbin Russwin keys. The facility's locksmith pins and installs the Corbin Russwin cylinder into the housing. Key system continuity is maintained without reordering or repinning.
