Schlage L583-047 – Frequently Asked Questions

1) What does the Schlage L583-047 catch spring actually do inside an L Series mortise lock?
The L583-047 is the catch spring inside the lock case of a Schlage L Series mortise lock. It is a small internal spring component that keeps the mechanism returning and latching consistently, so it is the part you order when an L Series lock is still mechanically sound but the latching action has gone sloppy. It is a service part, not a complete lock, so you are opening the case and swapping the spring rather than replacing the mortise body.
2) Will the L583-047 fit any Schlage mortise lock, or only the L Series?
Only the L Series. Schlage lists the L583-047 as designed exclusively for the L Series mortise lock family, so it is not a part to buy for Schlage bored locks or for another manufacturer's mortise case. If the lock body on your door is not an L Series, this spring is the wrong part.
3) Can I repair an L Series mortise lock with this spring instead of replacing the whole lock?
That is the point of it. The L583-047 is a drop-in replacement for the original factory-installed catch spring, so a facility can restore an L Series lock's function without pulling and rebuying the mortise body and trim. For a property manager standardized on L Series across a building, keeping a few of these on the shelf keeps openings in service instead of waiting on a full lock order.
4) Can a Corbin Russwin swivel spindle pin and set screw be used in place of the Schlage L583-047 catch spring?
No. The Schlage L583-047 is a catch spring, a genuine OEM replacement component made for the Schlage L Series mortise lock family and engineered as a direct drop-in for the original factory-installed catch spring. The Corbin Russwin Swivel Spindle Pin X Set Screw is a spindle pin with a set screw, rated for a 1-3/4 inch door thickness, and it serves the spindle/knob connection rather than the catch spring function inside the lock case. They are different parts in different manufacturers' lock platforms, so one cannot stand in for the other.
5) Is the L583-047 a genuine Schlage part or an aftermarket spring?
Genuine OEM. The L583-047 is sourced from Schlage and made to the factory specification for the L Series, which matters on a small internal spring where tension and tolerance decide whether the lock feels right after reassembly. Aftermarket springs in this position are the usual cause of a lock that works on the bench and binds in the door.
6) Does the L583-047 come with any other lock parts, or is it just the spring?
Just the catch spring. There is one item under the L583-047 part number, with no screws, no spindle and no trim included. If the teardown shows a worn spindle or hub as well, those are separate part numbers and need to be ordered alongside it.
7) I have a Corbin Russwin mortise lock, not a Schlage. Will this catch spring work?
No. The L583-047 is a Schlage L Series part and internal lock components do not cross brands. For Corbin Russwin service parts, ZenSupply carries items such as the Corbin Russwin Swivel Spindle Pin X Set Screw, which is listed for 1-3/4 inch doors. Match the repair part to the brand and series stamped on the lock case.
8) I am repairing a mortise lock and the spindle is loose, not the latch catch - which part do I need?
A loose or slipping spindle points to the spindle hardware, not the catch spring. The Corbin Russwin Swivel Spindle Pin X Set Screw addresses the spindle connection and is specified for a 1-3/4 inch door thickness. The Schlage L583-047 catch spring is the part to order when the catch mechanism inside a Schlage L Series mortise lock is no longer holding or returning properly; it is a commercial-grade OEM replacement part for that lock family. Confirm which manufacturer's lock is in the door before ordering, since these parts are not interchangeable across platforms.
9) Is the L583-047 catch spring rated for commercial door traffic or is it a residential part?
Commercial. Schlage classes the L583-047 as a commercial door hardware component, which is consistent with the L Series mortise platform it serves. It is used in offices, schools, healthcare facilities, government buildings, industrial sites, multi-tenant residential and retail.
