Schlage B520-744 – Frequently Asked Questions

1) Will the Schlage B520-744 cam work on an Adams Rite 4070 Series mortise lock?
Yes. The B520-744 straight mortise cylinder cam is made for use with Adams Rite 4070 Series mortise locks, so it drops in without modification when you are fitting a Schlage conventional mortise cylinder into that lock body.
2) What cylinder lengths does the Schlage B520-744 mortise cam fit?
It fits 1-1/4 inch, 1-1/2 inch and 1-3/4 inch conventional Schlage mortise cylinders, so one cam covers the three common lengths locksmiths carry for different door and lock-case depths.
3) Is the B520-744 a cam only, or does it come with a cylinder?
Cam only. The B520-744 is a replacement part, the straight tailpiece cam that bolts to the back of a conventional mortise cylinder. If your existing cylinder is good and only the cam is wrong or damaged, this is the piece you order; if you need the whole cylinder, order a Schlage conventional mortise cylinder separately in the length your lock case requires.
4) Do I need a straight cam or a clover/offset cam for my mortise lock?
The cam shape has to match the lock's retractor, not the cylinder. The B520-744 is the modular straight (classic) cam, which is what Adams Rite 4070 Series locks take. If your lock case uses a clover-leaf or offset cam, a straight cam will not drive the retractor and you need the cam specified for that lock instead. Pull the old cylinder and compare the cam profile before ordering.
5) I manage a building with mixed Schlage mortise cylinders. Can I standardize on one cam?
For openings running Adams Rite 4070 Series locks, yes. Because the B520-744 covers 1-1/4, 1-1/2 and 1-3/4 inch conventional cylinders, you can stock this single cam and still service doors of different thickness and lock-case depth across the portfolio. Openings using other lock cases with a different cam profile still need their own cam.
6) Will swapping to the B520-744 cam affect my keying?
No. The cam is the drive piece on the back of the cylinder and has nothing to do with the pinning or keyway, so changing a cam on a conventional mortise cylinder leaves your existing keys and master keying untouched.
7) Is the Schlage B520-744 cam rated for commercial door traffic?
It is a commercial-grade component, built to Schlage's commercial standards rather than a residential part. Typical use is office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and government facilities, which is where 4070 Series mortise hardware usually lives.
8) Is B520-744 a genuine Schlage part or an aftermarket cam?
Genuine Schlage. Model B520-744 is the OEM cam, so the fit and finish against a Schlage conventional mortise cylinder match factory spec, which matters when the rest of the cylinder is under an existing keying system.
