Schlage L583-639 – Frequently Asked Questions

1) What cylinder lengths does the L583-639 mortise cam fit?
It fits 1-1/4 inch, 1-1/2 inch, and 1-3/4 inch conventional mortise cylinders, so one cam covers the three common lengths you will find on commercial mortise openings. Check the cylinder you are pulling out before ordering, not the lock body.
2) Does this Schlage cam work with an interchangeable core cylinder?
No. The L583-639 is a conventional cylinder cam. It mates with standard conventional mortise cylinders in 1-1/4, 1-1/2 and 1-3/4 inch lengths. Small format or large format interchangeable core housings use their own cam or drive arrangement, so this part is not the one for an SFIC opening.
3) What is a mortise cylinder cam and why would I need to replace just the cam?
The cam is the small flat blade on the back of a mortise cylinder that turns with the plug and drives the lock body. Cylinders and lock bodies are sold separately, and the cam is what marries the two, so when a cylinder is swapped between brands or a cam is bent or the wrong shape, you replace the cam rather than the whole cylinder. The L583-639 is a straight cam, the geometry that engages the lockset directly.
4) Does the L583-639 come with a cylinder or screws?
It is the cam alone. Order the conventional mortise cylinder separately, along with the correct keyway and length for your opening, plus any cam screws your cylinder requires. The cam is a replacement component, not a cylinder kit.
5) Is the L583-639 rated for commercial use or is it a residential part?
Commercial. Schlage lists the L583 cam as a commercial door hardware replacement part, and it is used on mortise locksets in offices, schools, healthcare, retail, government buildings, warehouses and multi-tenant residential.
