Corbin Russwin 670F31 630 – Frequently Asked Questions

1) Is the Corbin Russwin 670F31 the whole mortise lock or just the lever trim?
Just the lever trim. The 670F31 is the inside lever component for the ML2000 Series mortise lock, not a complete lock. It mounts to an existing ML2000 mortise case and spindle assembly, so you still need a functioning lock body in the door. If the case itself is worn or the function is wrong, replacing this lever won't fix it.
2) Will the 670F31 lever work on a left-hand door?
No. The 670F31 is configured for right-hand (RH) and right-hand reverse (RHR) openings. On an LH or LHR door the lever would return upward instead of down, so you need the left-hand version of the same DS cast lever trim. Stand on the outside of the door: if the hinges are on your right, it's a right-hand opening and this is the correct part.
3) I have a broken lever on the inside of a Corbin Russwin mortise lock. Can I replace just that side?
Yes, that's exactly what the 670F31 is for. It's supplied as the inside lever only, so a snapped or sagging interior lever on an ML2000 mortise lock can be swapped without pulling the case or touching the outside trim. Confirm your existing lever is the cast DS style and that the opening is RH or RHR, since the part is handed.
4) What finishes does the Corbin Russwin DS inside lever trim come in?
Seven finishes: 605 Bright Brass, 606 Satin Brass, 611 Bright Bronze, 612 Satin Bronze, 619 Satin Nickel, 629 Bright Stainless Steel and 630 Satin Stainless Steel. If you're matching existing openings in a building, order by the BHMA number rather than the finish name, since the number is what's stamped on Corbin Russwin hardware.
5) Will this DS lever fit a Corbin Russwin ML2100 or other ML2000 function lock?
The 670F31 is built for the ML2000 Series mortise lock platform, which covers the ML2000-family function numbers. The lever trim itself doesn't change with the lock function, it changes with handing and lever style, so the deciding factors are that the case is an ML2000 series mortise lock, the opening is RH/RHR, and the existing trim is the cast DS design.
6) Do I need a different part number for the outside lever?
Yes. The 670F31 covers the inside lever only. Outside trim on an ML2000 mortise lock is a separate order, and on keyed functions it also carries the cylinder prep, so it isn't interchangeable with the inside lever. Order the matching outside DS trim in the same finish and handing so the pair looks and feels consistent.
7) Is the DS lever heavy-duty enough for a school or hospital corridor door?
It's a commercial-grade part, cast rather than tubular or pressed, and Corbin Russwin lists it for office buildings, schools, healthcare, government facilities, multi-tenant residential, retail and industrial use. Cast levers hold up better than wrought or hollow levers on doors that get leaned on and pulled hard all day.
8) Is the 670F31 a genuine Corbin Russwin part or an aftermarket copy?
It's a genuine Corbin Russwin replacement part, model 670F31, made to the ML2000 trim specification. For institutional buyers standardizing on Corbin Russwin, that matters: an aftermarket lever may seat on the spindle but rarely matches the finish or the lever profile across the rest of the openings.
