Abstract
A throw member having a first and second hub located along a blade that couples the rotation of the core cylinder with the rotation of the key cam of a lock chassis to lock and unlock a lock assembly. The two hubs are spaced apart to receive a catch. The catch constrains the throw member from releasing when the core cylinder or door lever is exchanged or modified. In addition, the two hubs enhance the throw member's ability to prevent unauthorized removal of the door lever. One of the two hubs includes a passage to release the throw member from the catch.
