Corbin Russwin 678F252 626 – Frequently Asked Questions

1) What exactly comes in the Corbin Russwin 678F252 rose pack, and is it a complete lock?
The 678F252 is a replacement rose pack only, not a lockset. It supplies the standard roses used with ML2000 Series rose trim configurations, so it is what you order when the roses are damaged, mismatched, or missing and the lockbody itself is fine. If you need the working lock, order the ML2000 lockbody and trim instead.
2) Which finishes does the Corbin Russwin 678F252 standard rose come in so I can match the rest of my doors?
Ten BHMA finishes are offered: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, and 722 black oxidized bronze oil-rubbed. For a building already standardized on Corbin Russwin trim, match the BHMA number stamped or specified on the existing hardware rather than matching by eye, since 612, 613 and 722 read very similarly on a dark door.
3) Will the 678F252 rose work with any ML2000 lock, or only certain trim styles?
It covers all cylindrical rose configurations in the ML2000 Series. If the opening uses escutcheon (plate) trim rather than roses, this pack is the wrong part, because escutcheon trim uses a full plate instead of a round rose.
4) Is this an OEM Corbin Russwin part or an aftermarket rose?
Genuine Corbin Russwin component for the ML2000 Series, so the fit and the finish match the original installation rather than approximating it. That matters on a maintenance program where roses get replaced a few at a time across a building and every opening has to still look alike.
5) Is the 678F252 rose pack rated for commercial traffic, or is it a residential part?
Commercial. It belongs to the ML2000 Series, which carries ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1, the top grade for that standard and what most office, school, healthcare and government specs call for.
6) Does the rose pack change the lock function or handing on an ML2000?
No. The rose is cover trim; function and handing live in the lockbody. ML2000 lockbodies use a quick reversible latchbolt that re-hands without opening the lock case, so swapping roses has no bearing on which way the door swings.
7) Do I need to know the door thickness or backset before ordering 678F252 roses?
The rose pack itself is not thickness-specific, but the ML2000 lock it dresses is built around a 1-3/4 inch (44mm) standard door with optional thicknesses available, and a 2-3/4 inch (70mm) backset. If the existing lock is an oversize-thickness build, confirm the trim on the door matches before you order roses for a batch of openings.
