Schlage 09-551 03L 626 – Frequently Asked Questions

1) What exactly is the Schlage 09-551 part, and what does it do on the lock?
The Schlage 09-551 is a mounting assembly, an OEM replacement component for Schlage commercial mechanical locks. It carries the exterior emergency turn assembly, the outside trim piece used on privacy openings so staff can release the lock from the corridor side. It is a repair part, not a complete lockset, so the lock chassis, latch and interior trim stay in place when you swap it.
2) Which lever style do I order for the Schlage 09-551 emergency turn assembly?
Order to match the lever design already on the opening. The 09-551 emergency turn assembly is offered in 03L, 03N, 05L, 06L, 07L, 07N and 17L styles. The L and N suffixes are different trim treatments within the same design number, so copy the code off the existing lock or its order record rather than guessing from the lever shape alone.
3) Can I repair a Schlage lock with a broken emergency turn instead of replacing the whole lockset?
Yes. That is what the 09-551 is for. Swapping the mounting assembly restores the emergency turn function on existing Schlage hardware without pulling and replacing the entire unit, which keeps the door prep, keying and interior trim untouched. Order the same lever style code and finish as what is on the door.
4) What finishes does the Schlage 09-551 emergency turn assembly come in?
Five finishes are offered across the 09-551 turn assemblies: 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome and 626 satin chrome. Not every finish pairs with every lever style, so pick the lever design first and then the finish that matches the rest of the trim on the door.
5) I manage a building with mixed finishes. Which 09-551 finish will match my existing Schlage trim?
Match the BHMA finish number stamped or specified on the existing hardware, not the look. 626 satin chrome is the most widely specified commercial finish and is offered here on the 03L, 03N, 06L, 07L and 07N turn assemblies, so a building standardized on 626 can usually stay on one finish across lever styles. 625 bright chrome is available on 06L and 17L, 605 bright brass on 03L and 06L, 613 oil rubbed bronze on 05L, 06L and 17L, and 619 satin nickel on 07L.
6) Is the Schlage 09-551 suitable for residential doors or is it commercial only?
It is a commercial part. The 09-551 mounting assembly is built for Schlage commercial mechanical lock systems in offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings. If you are repairing a residential-grade Schlage knob or lever, this is not the part.
7) Will a generic aftermarket turn assembly work in place of the Schlage 09-551?
The 09-551 is a genuine Schlage OEM part made to the original specifications, which is what gets you the correct fit into the Schlage chassis and the right alignment for smooth operation. Mixing in a non-Schlage assembly is not something the part is built for, and on commercial openings the alignment tolerance is what keeps the lock turning freely.
