Corbin Russwin 440F70-626 – Frequently Asked Questions

1) Is the Corbin Russwin 440F70 a complete lockset or just the rose trim?
It's a trim part only, not a lock. The 440F70 is a B cast rose, the round escutcheon plate that sits behind the knob or lever against the door face, sold as a single piece. You get one rose, no lockbody, no lever, no cylinder. If you need a working mortise lock you're ordering an ML2000 Series lockset and this is one of the trim pieces that goes on it.
2) I'm replacing one damaged rose on a school door - is this the right part to order on its own?
That's exactly what it's for. The 440F70 is a replacement B cast rose for ML2000 mortise locks, sold one at a time, so you can swap a single dented or corroded rose without pulling the lockbody or buying a whole new trim set. Confirm the lock is an ML2000 and that the surrounding trim is 626 satin chrome so the repair matches.
3) What finish does the Corbin Russwin 440F70 rose come in?
626 satin chrome, which is the standard commercial finish on most institutional openings. If the other roses and levers on your doors are 626 it will match; if the building is standardized on a brass or bronze finish, this one won't blend in.
4) Do I get one rose or a pair with the 440F70?
One. The 440F70 is sold as a single piece, so a door trimmed both sides needs two. Order in pairs if you're doing a full opening and one per side if you're just replacing a damaged or mismatched rose.
5) Does the rose change the handing or function of my ML2000 lock?
No. A rose is a round trim plate, it carries no handing and no lock function. The handing and function live in the ML2000 lockbody and the lever or knob; swapping the rose doesn't alter either, so you can order this without knowing the door's hand.
6) Is the 440F70 rose suitable for commercial and institutional buildings?
It's a commercial-duty part, cast rather than stamped, and it belongs to the ML2000 mortise line used in offices, schools, healthcare and multi-tenant buildings. For a property manager standardizing trim across a portfolio, cast roses hold up better to the knocks and cleaning chemicals that stamped trim shows quickly.
