Schlage B520-733 – Frequently Asked Questions

1) Which locks does the Schlage B520-733 mortise cam actually fit?
The B520-733 cam is made for Corbin Russwin ML2200 Series mortise locks, plus Corbin 7000-9000 and Russwin 4000-5000 series lock bodies built before June 10, 1993. The 42/55 Interior models are the exception, this cam is not for those. If your lock body was produced after that June 1993 cutoff, this is the wrong cam.
2) Will one B520-733 cam work with a 1-1/2 inch mortise cylinder, or do I need a different cam for each cylinder length?
One part covers the range. The Modular Clover Mortise cam is listed for 1-1/4, 1-1/2 and 1-3/4 inch conventional mortise cylinders, so you order the same cam whatever of those three lengths your opening takes. Cylinder length is set by door and trim thickness, the cam is not what changes.
3) I have a box of Schlage mortise cylinders, can I use them in old Corbin Russwin ML2200 locks?
That is exactly what this cam is for. Schlage conventional mortise cylinders ship with a standard Schlage cam that will not drive a Corbin Russwin lock body correctly. Swapping in the B520-733 Modular Clover Mortise cam gives the cylinder the cam geometry those pre-June-1993 Corbin 7000-9000, Russwin 4000-5000 and ML2200 lock bodies expect, so a property or campus already standardized on Schlage keying can keep the legacy mortise bodies in service.
4) Does the B520-733 work with interchangeable core cylinders?
No. It is a conventional mortise cylinder cam, meant for standard keyed mortise cylinders rather than small or large format interchangeable core housings. If you are converting an opening to IC, the cam is not the part that gets you there.
5) Do I get the cylinder with the B520-733, or just the cam?
Just the cam. The B520-733 is the cam alone, a replacement part that mounts to a conventional mortise cylinder you already have or order separately. Budget for the cylinder, and the cam screw if yours is missing, on the same job.
6) My Corbin Russwin mortise lock turns the key but the latch does not retract, is the cam the problem?
Often, yes. On a mortise cylinder the cam is the tail that pushes the lock body's hub, so a worn, bent or simply wrong-profile cam will let the key rotate with no mechanical result. On pre-June-1993 ML2200, Corbin 7000-9000 and Russwin 4000-5000 bodies, the B520-733 Modular Clover cam is the correct profile to restore that engagement without replacing the lock body.
7) Is the B520-733 a commercial part or a residential one?
Commercial. The cam is a Schlage replacement part for commercial mortise lock hardware, the kind of work that shows up in office buildings, schools, hospitals and municipal facilities where pre-1993 Corbin Russwin mortise bodies are still hanging in the doors.
