Schlage L583-496 – Frequently Asked Questions

1) Will the Schlage L583-496 lock case cover fit my L9000 mortise lock?
The L583-496 case cover is made for Schlage L9000 Series mortise locks manufactured after January 1998. If the lock body in your door predates that cutoff, the cover is not the right part. Check the date code or production era of the lock case before pulling it off the door.
2) Is the L583-496 a genuine Schlage part or an aftermarket cover?
It's a genuine OEM Schlage component, sold under the Schlage parts program, so it goes on the L9000 case without modification. For a locksmith or maintenance tech that matters: an aftermarket cover that sits proud can bind the mortise case in the pocket.
3) What does a mortise lock case cover actually do, and do I need one if mine is damaged?
The cover closes off the internal lock case assembly of the mortise lock, holding the working parts in place and protecting them. If yours is bent, stripped at the screw bosses, or missing after a service call, the case can't be trusted to stay together in the door. Replacing the cover is the fix rather than swapping the whole mortise lock.
4) Can I use the L583-496 to standardize spare parts across a building full of Schlage L9000 locks?
That's the usual reason people buy it. One cover part number serves the L9000 Series mortise locks built after January 1998, so a facility with those locks on multiple openings can stock the L583-496 as a common spare instead of holding complete lock bodies.
5) Does the L583-496 include the lock case, trim, or cylinder?
No. The L583-496 is the case cover only, a replacement part for an L9000 mortise lock you already have in the door. Lever trim, cylinder, and the lock case itself are ordered separately.
6) Is the L583-496 rated for commercial door traffic?
Yes. It's classified as a commercial part, built to the same standards as the L9000 Series line it serves, which is Schlage's commercial mortise lock family used in offices, schools, healthcare, and government buildings.
