Corbin Russwin 493F31-626 – Frequently Asked Questions

1) Is the Corbin Russwin 493F31 the whole mortise lock or just the lever?
Just the lever. The 493F31 is the inside lever only, in the LW Lustra Wrought design, sold as a replacement part for ML2000 Series mortise locks. There's no lock case, no cylinder, and no strike with it, so if the lock body itself is worn or you're changing function, you need an ML2000 lockset instead. Use this when the lock works fine and the handle is broken, bent, or you're standardizing handle style across a building.
2) Will the 493F31 lever fit any Corbin Russwin ML2000 mortise lock, or only certain functions?
The 493F31 is the ML2000 Series inside lever and mounts to that platform's trim. The catalog function tied to it is corridor/dormitory, which is the common classroom-corridor and dorm-room setup where the inside lever is always free for egress. If the opening you're working on is an ML2000 in a corridor or dorm application, this is the matching inside handle. Match the lever design too: LW Lustra Wrought is one of several ML2000 trim designs, and pairing it with a different design on the outside gives you mismatched handles on the same door.
3) Do I need to order the Corbin Russwin LW inside lever left hand or right hand?
No handing to specify. The LW inside lever is field reversible, and the ML2000 lock it goes on uses a quick reversible latchbolt that re-hands without taking the lock case apart. One part number covers both hands, which is what you want when you're stocking spares for a building with doors swinging both ways.
4) My ML2000 won't latch since the handle got replaced. Does the inside lever change the backset or latch throw?
No. Backset and throw belong to the lock case, not the handle, so a lever swap doesn't move anything in the door prep. The ML2000 runs a 2-3/4 inch (70mm) backset with a 3/4 inch (19mm) anti-friction two-piece latchbolt, a 9/16 inch (14mm) deadlocking auxiliary latchbolt, and a 1 inch (25mm) throw stainless deadbolt into an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If it stopped latching after a trim change, look at spindle engagement and the thru-bolts, not the strike.
5) Can I keep my existing cylinder and keying when I service a Corbin Russwin ML2000 mortise lock?
Yes on both counts, and the inside lever has nothing to do with keying anyway. The ML2000 works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, with a brass 6-pin L4 keyway 0-bitted as the factory standard. Center to center from lever to cylinder is 3-5/8 inches (92mm), and lever to thumbturn is 2-7/16 inches (62mm), which is what governs whether escutcheon trim lines up with the existing door prep.
6) Can I use the Corbin Russwin LW lever on a behavioral health or psychiatric unit door?
No. The LW Lustra Wrought lever is a conventional lever and it's a ligature point. Corbin Russwin makes dedicated behavioral health trim for the ML2000 platform, designated BHSS and BLSS, and that is what belongs on a patient room or psych unit door. Other ML2000 trim designs include Museo and Vineyard if you're after a different look on a standard opening.
7) What finishes does the Corbin Russwin 493F31 ML2000 inside lever come in?
Eleven finishes, so you can match what's already hanging on the other doors: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, 629 bright stainless, 630 satin stainless, and 722 black oxidized bronze oil-rubbed. For institutional corridors, 626 and 630 are the two you'll see most on existing ML2000 openings.
8) Is the Corbin Russwin LW lever ADA compliant for a school or healthcare corridor?
Lever operation, and the ML2000 platform it belongs to is certified to ADA A117.1. Levers are the reason: no tight grasping or wrist twisting to retract the latch. That, plus Grade 1 operational and security rating, is why these show up on dorm, classroom, and hospital corridor doors.
9) How much traffic will a Corbin Russwin ML2000 lever hold up to before it needs replacing?
The ML2000 lockset is UL cycle verified to 14.5 million cycles (verification ID V875753), well past the Grade 1 threshold. That's the reason a bent or worn inside lever on a high-traffic dorm or corridor door is usually the only part that needs swapping while the lock case keeps running. The trim is thru-bolted, which keeps the lever aligned and resists someone pulling the handle off the door.
10) Will a Corbin Russwin ML2000 lever work on a door thicker than 1-3/4 inches?
Standard ML2000 trim is built for 1-3/4 inch (44mm) doors, and that's what ships unless you specify otherwise. Optional thicknesses are available from Corbin Russwin, but they're an order-time choice, not something you adjust in the field, so measure the leaf before you order a replacement lever for an unusual door.
11) Should I replace just the lever or the whole ML2000 mortise lock?
Replace the lever when the lock case still throws and retracts cleanly and only the handle is damaged, sagging, or mismatched. Replace the lockset when the function needs to change, since the ML2054 body configures to 12 different functions and the handle can't do any of that, or when the case itself is failing. One more case for the full lockset: motorized electric latch retraction is only available on the ML20900 series, so an access-control retrofit is a lock body decision, not a trim one.
