Corbin Russwin 488F31-626 – Frequently Asked Questions

1) Does the Corbin Russwin 488F31 half dummy trim actually latch, or is it just a pull?
It's a dummy. The 488F31 is a half dummy trim, meaning a lever on a P escutcheon fixed to one face of the door with no latch, no spindle action and no locking. It's there to give a non-operational leaf (an inactive door, a closet face, a blank opening) the same look as the working doors. If you need the door to latch, you need an ML2000 mortise lockbody with operating trim instead.
2) Will the 488F31 lever trim match my existing Corbin Russwin ML2000 mortise locks?
Yes, that's the point of it. The 488F31 is built for the ML2000 Mortise Lock Series, so the lever design and P escutcheon are drawn from the same trim family used on the operating ML2000 locks. Order it in the same finish as the working doors and the inactive leaf reads identically.
3) Can I put a half dummy on the inactive leaf of a pair and keep the ML2000 lock on the active leaf?
That's the normal use. The active leaf carries the ML2000 mortise lock with its 3/4 inch throw anti-friction latchbolt and, where specified, the 1 inch stainless deadbolt; the inactive leaf takes the 488F31 so both doors show the same lever and escutcheon. Just match the finish and keep the trim height consistent between the two leaves.
4) What finish does the Corbin Russwin 488F31 dummy trim come in?
626 satin chrome. That's the standard commercial finish and it will sit alongside 626 exit devices, closers and ML2000 lock trim on the same run of openings without a visible mismatch.
5) Is a dummy trim handed? Do I need to order left or right hand?
Lever trim is handed in the sense that the lever has to point toward the hinge side on the face it's mounted to. On a half dummy you're only trimming one face, so decide which side of the opening gets the lever and which way it should throw before you order. The ML2000 operating locks are quick reversible in the lock case, but a dummy has no case to re-hand.
6) Do I need to cut a mortise pocket in the door for the 488F31?
No mortise pocket is needed. A half dummy trim is surface-applied to one face and fastened through the door, so you're drilling for fasteners, not routing a lock case pocket the way you would for a live ML2000 mortise lock (whose case runs 5-7/8 x 4 x 15/16 inches). That makes it a practical way to dress an inactive leaf without machining it for a full lock.
7) Does the 488F31 come with a cylinder or keyway?
No cylinder. A half dummy has nothing to key. Cylinders belong to the operating ML2000 locks, which take a 6-pin L4 keyway brass cylinder 0-bitted as standard and will also accept most other manufacturers' cylinders. If you are keying a building, spec those on the live openings and leave the dummy leaves as trim only.
8) Is this an interior-grade part or is it suitable for institutional buildings?
It is a commercial part, catalogued for door hardware in commercial use, and the ML2000 family it trims out is specified across offices, schools, healthcare, retail, government and multi-family. The trim carries no rating of its own, since it has no working mechanism, but it is the finish-matching piece for Grade 1 ML2000 openings.
