Schlage Commercial B520-296 Mortise Cylinder IC Cam, Yale 2160, Arrow 004, Sargent 13-0660, All Functions Except 16 Inside and 50 Outside

The B520-296 is the cam that mounts on the back of a Schlage interchangeable core mortise cylinder. The cam is the driver that transfers cylinder rotation into the mortise lock body, so it is the piece that has to match the lock you are installing into, not the cylinder itself. Order it when you are fitting an IC mortise cylinder into a lock case that calls for this cam pattern.

Yes. The B520-296 is the cross-reference for the Yale 2160 cam, the Arrow 004 cam and the Sargent 13-0660 cam, so a Schlage IC mortise cylinder fitted with it will drive those manufacturers' mortise lock bodies. That is what makes it useful to a locksmith standardizing a building on one Schlage keyway while leaving mixed lock brands in the doors.

It covers all functions except the 16 function inside and the 50 function outside. If your opening uses a 16 inside or a 50 outside, this is the wrong cam and you need the cam specified for those functions instead. Every other mortise function is served by the B520-296.

For a Schlage interchangeable core mortise cylinder, yes. The B520-296 is the Schlage cam that corresponds to the Sargent 13-0660, along with Yale 2160 and Arrow 004. Confirm your lock function first, since the 16 inside and 50 outside functions are the two this cam does not cover.
