Schlage B520-729 – Frequently Asked Questions

1) What cylinder lengths does the Schlage B520-729 mortise cam fit?
The B520-729 straight mortise cam is made for conventional cylinders in 1-1/4, 1-1/2 and 1-3/4 inch lengths, so one cam covers the three common mortise cylinder depths you run into on commercial openings. If your cylinder is one of those three conventional lengths, this cam is the right part.
2) Is the Schlage B520-729 the right cam for a Corbin Russwin Master Ring cylinder?
Yes. The B520-729 is specifically intended for use with the Corbin Russwin Master Ring, giving the correct cam-to-cylinder engagement on those cylinders. That is the stated application for this cam, and it is what separates it from other cams in the B520 family.
3) Will a straight cam work in my mortise lock, or do I need an offset or clover cam?
A straight cam like the B520-729 drives the lock case directly in line with the cylinder, which is what most standard commercial mortise lock cases take. Offset and clover style cams exist because certain lock cases and exit device cases need the actuator moved off center or turned to a different position. If the cam you pulled out of the cylinder is straight, replace it with a straight cam; if it was stepped or lobed, the B520-729 is not the match.
4) I'm a locksmith rekeying a job. Does a mortise cylinder cam need to be ordered separately from the cylinder?
Yes, the cam is a separate service part. The B520-729 is sold as a replacement cam only, so you are ordering it when a cam is damaged, when the wrong cam style came in the cylinder, or when you are converting a conventional cylinder to suit a Corbin Russwin Master Ring application. The cylinder, plug, keys and pins are not part of it.
5) Is the Schlage B520-729 cam a genuine Schlage part or aftermarket?
It is a genuine Schlage replacement part, catalogued under model B520-729. For facilities standardizing on Schlage cylinders, that matters because the cam bears on the plug and the lock actuator, and dimensional accuracy decides whether the key turns smoothly through its full rotation.
6) Is this cam meant for commercial mortise locks or residential hardware?
Commercial. The B520-729 is a commercial-grade mortise cylinder cam used in office buildings, schools, healthcare and government facilities, retail, industrial buildings and multi-tenant residential properties. It is a mechanical lock service part, not something you would find in a residential knob set.
7) Does the B520-729 come in different finishes or sizes I need to pick from?
No options to choose. The B520-729 is a single orderable part number, with the same cam covering conventional cylinders at 1-1/4, 1-1/2 and 1-3/4 inches. Nothing to specify beyond quantity.
