Schlage L583-028 – Frequently Asked Questions

1) What is the Schlage L583-028 and which locks does it go with?
The L583-028 is a fire door catch, a replacement component for Schlage L Series mortise locks. It restores the catch function inside an L Series mortise case used in a fire-rated door assembly. It is made for the L Series line only, so it is not a part you drop into a bored/cylindrical lock or another manufacturer's mortise case.
2) I need a latch for a bored residential door, not a mortise lock - what should I order instead of the L583-028?
The L583-028 is a Schlage L Series mortise lock part and is designated for commercial use, so it is not the right piece for a bored residential door. For drive-in tubular applications, the Deltana DLE23875 drive-in latch is an entry function unit and the Deltana DLP23875 is a passage/privacy drive-in latch with an adjustable 2-3/8 inch or 2-3/4 inch backset; both cover a 1-3/8 inch to 2 inch door thickness range. Choose by the function of the lock you are repairing.
3) Can a Kwikset UL-rated tubular latch be used in place of the Schlage L583-028 fire door catch?
No. The Schlage L583-028 is a replacement fire door catch built for the Schlage L Series mortise lock line, so it fits inside a mortise lock case rather than a bored tubular prep. Kwikset tubular latches such as the 83521 RCAL plain latch and the 84290 square corner plainlatch with a 2-3/8 inch backset are drive-in/faceplate latches for bored doors and will not seat in an L Series mortise case. For an L Series mortise lock, use the genuine L583-028 component.
4) Do I have to order a whole new Schlage mortise lock, or can I just replace the fire door catch?
The catch is sold on its own as a service part, so a mortise case whose catch has failed can be repaired rather than replaced. It is built to Schlage factory specifications for the L Series, which is why it goes back into the existing case without modifying the door or the mortise pocket.
5) Will the L583-028 fire door catch match the other L Series mortise locks across my building?
Yes, as long as those openings use Schlage L Series mortise hardware. The catch is an internal functional component, so there is no finish or trim to match, and standardizing on the single model number L583-028 keeps one line item on the shelf for every L Series fire door in the portfolio.
6) Does using a genuine Schlage catch matter for keeping a fire door assembly compliant?
It does. A fire door assembly has to latch to perform, and the L583-028 is the Schlage-specified catch for L Series mortise locks in fire-rated openings. Substituting a non-Schlage improvised part changes a listed assembly's hardware, which is exactly what an inspector looks at. Using the factory part keeps the repair like-for-like.
7) Is the Emtek 83228 pocket door privacy faceplate a substitute for the Schlage L583-028?
No. The Emtek 83228 is a faceplate and screw set for a tubular pocket door privacy latch with square corners, a privacy/bed/bath function part. The Schlage L583-028 is the fire door catch that goes inside an L Series mortise lock in a fire-rated swinging door assembly. The two serve different lock types and different openings, so they are not interchangeable.
8) For a fire-rated opening, how does the Schlage L583-028 differ from a Kwikset 83518 UL 3 hour latch?
The Kwikset 83518 is an RCAL adjustable square drive latch carrying a UL 3 hour rating for bored residential-style locksets. The Schlage L583-028 is the fire door catch for Schlage L Series commercial mortise locks and is installed within the mortise case to restore proper latching in a fire-rated assembly. Match the part to the lock body already in the door: mortise prep takes the L583-028, bored prep takes a tubular latch such as the 83518.
9) Is the Schlage fire door catch a residential part or a commercial one?
Commercial. The L583-028 is catalogued as a commercial-grade replacement part, and the applications behind it are offices, schools, healthcare, government buildings, hotels and multi-tenant residential with fire-rated openings. For a house door with a standard bored lock, this is the wrong part.
10) What is the difference between the L583-028 and a deadbolt latch like the Emtek LC9-DBLTCH?
The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, an electrified locking component for a deadbolt. The Schlage L583-028 is a mechanical fire door catch supplied as a genuine replacement part for the L Series mortise lock line, used to restore proper catch function in fire-rated door assemblies. One is a powered deadbolt component, the other a mechanical mortise lock internal part.
