Schlage B520-366 – Frequently Asked Questions

1) What lock bodies does the Schlage B520-366 mortise cam fit?
The B520-366 cam is made for Corbin Russwin DL4000 Series mortise lock bodies, and it also covers the Corbin 420 and Russwin 1503 configurations. It drops in on those assemblies without modification.
2) Will the Schlage B520-366 cam work on a cylinder made after July 2010?
No. The B520-366 is built for Pre-July 2010 Everest and Primus conventional cylinder configurations. Schlage changed the cam interface after that date, so if your cylinder is a later production Everest or Primus, this straight cam is the wrong part for it.
3) Is the B520-366 a modular cam or a non-modular one?
Non-modular. It is a one-piece straight mortise cam, not part of Schlage's modular cam system, so it will not interchange with modular cam tailpieces. The straight geometry drives the mortise lock hub directly with no adapter.
4) I'm replacing a worn cam in a Corbin Russwin mortise lock in an office building. Is this the right kind of part?
If the cylinder is a pre-July 2010 Schlage Everest or Primus conventional cylinder feeding a DL4000 Series body, yes, this is the service cam for it. It is a genuine Schlage replacement part intended for commercial mechanical lock work, which covers offices, schools, healthcare and hospitality openings running that legacy hardware.
5) Do I get a whole cylinder with the B520-366, or just the cam?
Just the cam. The B520-366 is the cam component alone, ordered to rebuild or convert an existing Schlage mortise cylinder. You reuse your cylinder and keying; if you also need the cylinder itself, that is a separate order.
6) Does the B520-366 cam change how the lock is keyed?
No. The cam only transfers plug rotation to the lock body; pinning and keyway stay in the cylinder. Swapping to the B520-366 keeps your existing Everest or Primus keying intact as long as the cylinder is a pre-July 2010 conventional one.
7) Is there more than one version of the B520-366 to choose from?
No options to specify. The B520-366 ships as a single configuration, so there is no finish, hand, or length choice to make when ordering.
