Schlage L583-023 – Frequently Asked Questions
1) What does the Schlage L583-023 blocking plate actually do on an L Series mortise lock?
The L583-023 is a blocking plate for Schlage L Series mortise locks. It covers an unused opening or gives a finished surface where a lever, trim, or function option needs blocking, so the lock face and trim look complete instead of leaving a hole exposed. It is a genuine Schlage replacement component, not a universal filler plate.
2) Can I buy just this plate instead of replacing the whole mortise lockset?
That is the point of the part. The L583-023 is a replacement component, so if you are repairing or reconfiguring an existing L Series installation you swap the plate and leave the lock body, cylinder, and trim in place.
3) I manage a building with Schlage L Series locks on every door. Will this plate match the rest of my openings?
It is the factory part for the L Series, machined to L Series dimensions and tolerances, so it lines up with the trim already on your doors rather than sitting proud or leaving a gap. When you are standardizing across a floor or a building, ordering the OEM plate keeps the look consistent across every opening.
4) Is the L583-023 rated for commercial door traffic or is it a residential part?
Commercial. It belongs to Schlage's commercial L Series line and is used in offices, schools, hospitals, government buildings, hotels, and multi-family properties where L Series mortise locks are already installed.
5) Is the L583-023 a single part number or do I pick a size or handing?
One part, one number: L583-023. There is no handing, size, or length choice to specify when you order it.
