Resolution

The Schlage B502-191 cam does not work with the Modular Cylinder design (released around 2011.)

 

The B502-191 should be replaced with either:

  • L583-474 (1 1/8” cylinder), 
  • L583-475 (1 ¼” cylinder). 

 

(This article written in 2016.  The Von Duprin catalog is slated to be corrected by removing references to the B502-191.)

 

 

 

 

 

 

Can you have the Von Duprin literature reviewed and updated to reflect the cam change?  The B502-191 should be replaced with either the L583-474 (1 1/8” cylinder) or L583-475 (1 ¼” cylinder).  See attached.
