Corbin Russwin 678F00-8RR – Frequently Asked Questions

1) What does the RHR suffix on the Corbin Russwin 678F00-8RR mean, and will it work on a left hand door?
RHR is Right Hand Reverse, and that is the only handing this lock body is built for. A Right Hand Reverse door is hinged on the right as you face it and swings toward you. If your opening is left hand, left hand reverse, or right hand (inswinging), the 678F00-8RR will not function correctly and you need the case built for that handing instead. Stand on the outside of the door, note the hinge side and the swing direction, and confirm before you order.
2) Can I replace just the mortise lock body instead of the whole Corbin Russwin exit device?
That is exactly what the 678F00-8RR is for. It is a genuine Corbin Russwin replacement part that restores latching function to an ED5610 or ED5655 thumbpiece device without pulling and re-prepping the whole exit device. For a property manager or in-house maintenance crew, that means the existing door prep, trim, and push rail stay put and only the case comes out.
3) Is the 678F00-8RR a complete exit device or just a component?
Component only. The 678F00-8RR is the mortise case, the core locking mechanism inside an ED5610 or ED5655 assembly. It is not a push bar, not a thumbpiece trim, and not a cylinder. If you are building a device from scratch rather than repairing one, you need the full ED5610 or ED5655 device, not this case on its own.
4) How do I make sure I order the correct handed mortise case for a Corbin Russwin ED5655?
Two things decide it: the device model and the handing. Confirm the device on the door is an ED5610 or ED5655 thumbpiece model, then confirm the opening is Right Hand Reverse. Match both and the 678F00-8RR is the right case. The suffix 8RR on the part number is the handing call-out, so the part number itself tells you which door it belongs on.
5) Is the Corbin Russwin 678F00-8RR rated for commercial door traffic?
It is a commercial-duty part. Corbin Russwin builds the 678F00-8RR for commercial door hardware service, and it is used in office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential, and government buildings. It is not a residential-grade item.
