Schlage B520-360 – Frequently Asked Questions
1) What does the Schlage B520-360 cam actually do in an interchangeable core lock?
The B520-360 is the tailpiece cam that mounts on the back of a small format or full size interchangeable core (SFIC/FSIC) mortise housing. It transfers the turn of the core to the lock mechanism. It is a clover-style, non-modular cam, so the shape has to match the housing and lock it drives. It is a commercial-grade part made of stainless steel.
2) I have a Corbin Russwin ML2200 deadbolt but I do not know its age. Does the B520-360 cam still apply?
Date matters on this one. The cam is called out for the Corbin Russwin A65 and ML2200 master ring deadbolt manufactured before June 10, 1993. If your deadbolt is newer than that cutoff, this clover cam is not the one specified for it, and forcing a mismatched cam will leave the core turning without throwing the bolt. Pull the existing cam and match the shape before you order.
3) Can I standardize one cam across all the mortise IC cylinders in my building?
Only where the lock bodies match. The B520-360 clover cam covers Corbin Russwin A65 and pre-June 10, 1993 ML2200 master ring deadbolts, Russwin cast iron residential locks, and BEST 30H/40H. Openings running other lock families or newer Corbin Russwin deadbolts need the cam specified for those, so inventory this one for the doors it fits rather than as a universal spare.
4) Can I use a Schlage-branded cam on a BEST lock?
Yes, for the BEST 30H and 40H series. Cams are keyed to the geometry of the lock mechanism, not to the brand on the package, and the B520-360 clover cam is specified for those two BEST series as well as for Corbin Russwin and Russwin applications.
5) Is the B520-360 cam for small format or full size interchangeable cores?
Both. It is listed as an SFIC/FSIC mortise cam, so it covers small format and full size interchangeable core mortise housings within the lock families it is specified for.
6) What does non-modular mean on a mortise cylinder cam, and does it change what I order?
Non-modular means the cam is a fixed one-piece part in a set shape, not part of a modular system where you swap cam blades on a common carrier. You order it by its shape and application, the clover pattern for the Corbin Russwin, Russwin and BEST locks named for it, rather than by assembling a cam and adapter.
7) Do I get a core or a cylinder with the Schlage B520-360?
No. The B520-360 is the cam alone, the driver piece that attaches behind an interchangeable core mortise housing. The core, the housing, and any keying are separate items you supply or order.
8) Will this cam hold up on a high-traffic commercial opening?
It is a commercial door hardware part made of stainless steel, so it suits the mortise IC housings on institutional and commercial openings rather than light residential duty. The one exception in its own application list is Russwin cast iron residential locks, which it also serves.
