Corbin Russwin 678F248 – Frequently Asked Questions

1) What door thickness does the Corbin Russwin 678F248 rose liner cover?
The 678F248 rose liner is sized for doors 1-3/4 inches to 2 inches thick. Standard commercial doors run 1-3/4 inches, so this covers the common opening plus thicker doors up to 2 inches. If your door is thinner than 1-3/4 inches, this is the wrong liner length and you need the thinner-door version of the part.
2) What exactly does a rose liner do on a cylindrical lock?
The rose liner is the sub-plate that mounts to the lock body and door face, and the visible rose snaps or threads onto it. It sets the trim standoff for the door thickness and keeps the rose seated square. It is not the rose itself and it is not the lock chassis, so replacing a 678F248 fixes loose or misaligned outside trim without pulling the whole lockset.
3) Can I use the 678F248 liner on a residential lockset?
It is a commercial part, built for Corbin Russwin cylindrical lock assemblies used in offices, schools, healthcare, retail and multi-tenant buildings. It is not a universal liner and will not fit residential-grade knob or lever sets from other makers. Match it to a Corbin Russwin cylindrical chassis.
4) My Corbin Russwin lever trim is wobbling on the outside of the door. Do I need a whole new lockset?
Often not. If the chassis and latch still operate correctly and only the outside rose is loose or sitting proud, the 678F248 liner is the piece that restores the seating. It is sold as a genuine Corbin Russwin replacement part, so the trim goes back to its original fit and finish without swapping the full assembly.
5) If I am standardizing Corbin Russwin hardware across a building, is the 678F248 the one liner I stock?
Only for openings with 1-3/4 to 2 inch doors, and only for the outside face. A fleet of standard 1-3/4 inch commercial doors is fully covered by it, but thinner doors and the interior side of each opening take different liners. Stock accordingly rather than assuming one liner covers every door.
