Schlage K510-320 – Frequently Asked Questions

1) What does the Schlage K510-320 wooden dummy plug actually do?
It fills a mortise cylinder bore where no working cylinder is needed. The K510-320 is a non-operational plug, so it occupies the cylinder opening cleanly and keeps the lock assembly looking and sitting right without adding a keyed function. Common use is a door leaf or trim that's prepped for a cylinder you don't want live.
2) Which Schlage cylinders is the K510-320 plug made for?
Schlage L0170 and L0172 mortise cylinder applications. It's a genuine Schlage part built for that fit, so if your hardware is an L0170 or L0172 setup this is the matching dummy plug. For other cylinder families, it is not the part to order.
3) Is this a keyed cylinder or just a filler? I need a working lock.
Just a filler. The K510-320 has no keyway and no operating mechanism, so it will not lock or unlock anything. If you need a functioning mortise cylinder plug assembly instead, look at a keyed mortise cylinder such as the Corbin Russwin 121K11 series plug (121K11-D2 or 121K11-L4 in the 1000 Series).
4) Can a Corbin Russwin 121K11 mortise cylinder plug be used in place of the Schlage K510-320?
No. The Schlage K510-320 is a wooden dummy mounting plug that fills the cylinder bore in Schlage L0170 and L0172 mortise cylinder applications when no working cylinder is needed, so it is non-operational by design. The Corbin Russwin 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs supplied as a plug only for a functioning cylinder. Different job entirely: one blanks off the prep, the other is a keyed cylinder component sized to the Corbin Russwin 1000 Series body.
5) My opening uses a rim cylinder, not a mortise cylinder - is the K510-320 still the right plug?
No. The Schlage K510-320 is built for Schlage L0170 and L0172 mortise cylinder applications. For rim cylinder work, the Corbin Russwin 253K66 is a 3000 Rim Cylinder Plug. Check the cylinder body on the door first: mortise cylinders thread into the lock case, rim cylinders mount through the door behind a rim exit device or rim lock.
6) Do I have to replace the whole lock to blank off a cylinder hole?
No. The K510-320 is a replacement-part-level fix: it drops into the existing L0170/L0172 cylinder location so you can reconfigure or maintain the hardware without pulling and replacing the full assembly. That's the main reason property managers and MRO buyers stock it.
7) What is the K510-320 made of, and will wood hold up in a high-traffic door?
Wooden construction. Schlage specifies it as a commercial-grade fill solution, and because it's a static plug with no moving parts there's nothing to wear mechanically. It is not a security component though, so it should only be used where the opening does not depend on that cylinder position for locking.
8) I need a part to retain a cylinder plug, not a dummy plug. Is this it?
No. The K510-320 fills the bore; it is not a retainer. For a retaining component, the Corbin Russwin 219F88-8 is a Grade 1 cylinder plug retainer. And if you're working on a rim cylinder rather than a mortise cylinder, the Corbin Russwin 253K66 is a 3000 Series rim cylinder plug.
9) What is the difference between the Schlage K510-320 and the Corbin Russwin 219F88-8?
The Corbin Russwin 219F88-8 is a Grade 1 cylinder plug retainer - the small component that holds a plug in place within the cylinder. The Schlage K510-320 is the plug itself, a wooden dummy mounting plug used with Schlage L0170 and L0172 mortise cylinders to close off the bore when no operating cylinder is fitted. A retainer is not a substitute for a plug, and the 219F88-8 is a Corbin Russwin part rather than a Schlage one.
10) Is the K510-320 suitable for commercial buildings, or is it a residential part?
It's classed as commercial door hardware. Schlage builds it for commercial mortise assemblies, which is where L0170/L0172 cylinders live, so it fits facility work in offices, schools, healthcare, and multi-tenant residential running commercial-grade hardware.
