Corbin Russwin 493F34-626 – Frequently Asked Questions

1) Is the Corbin Russwin 493F34 lever handed, or can I use the same part on left and right hand doors?
Field reversible. The same lever works on either hand, and the ML2000's quick reversible latchbolt lets the lock be re-handed without taking the lock case apart. For a property manager stocking spares across a building, that means one lever part number covers every opening regardless of swing.
2) I need the outside lever too, not just the inside one. Does the 493F34 cover both sides of the door?
Inside only. The 493F34 is the inside lever for an ML2000 mortise lock, so on a corridor or dormitory function the keyed outside lever is a separate part. Order the matching outside trim in the same finish number, or you end up with two different shades on one door.
3) Does replacing the lever on a Corbin Russwin ML2000 affect the fire rating on the door?
The ML2000 mortise lock is UL/cUL listed to UL10C positive pressure and rated for 3-hour fire doors up to 4 ft x 10 ft single or 8 ft x 10 ft pair. Using the manufacturer's own ML2000 lever trim keeps that listing intact; substituting a generic lever on a labeled fire door is what puts it at risk. The lock is also ADA A117.1 compliant, which is why the lever style matters on accessible openings.
4) What backset and door thickness does the Corbin Russwin ML2000 mortise lock use?
2-3/4 inch backset and 1-3/4 inch (44mm) standard door thickness, with optional thicknesses available. If your existing mortise pocket was cut for a 2-3/4 inch backset, which is the standard commercial mortise backset, the ML2000 drops into the same prep and the lever spindle lands where it should.
5) Will a Corbin Russwin ML2000 latch into the strike I already have in the frame?
The latchbolt throws 3/4 inch (19mm) and is a two-piece anti-friction design, with a 9/16 inch (14mm) auxiliary deadlatch alongside it. The deadbolt throws a full 1 inch. The factory strike is an ANSI straight lip, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. If your frame already carries a 4-7/8 inch ANSI strike prep, the lock latches into it; a smaller T-strike or a residential lip won't line up.
6) What finishes does the Corbin Russwin 493F34 ML2000 inside lever come in?
Eleven finishes: 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. If you are matching an existing opening, the finish number is usually stamped or listed on the original hardware schedule, and 626 satin chrome and 630 satin stainless are the two most common on commercial corridor doors.
7) Is the Corbin Russwin ML2000 lever Grade 1, and what does that mean for a dorm or school corridor?
ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, which is the top commercial mortise rating. The ML2000 lockbody behind it is UL cycle verified to 14.5 million cycles. That is the durability level you want on a dormitory or school corridor door that gets used hundreds of times a day.
8) How far apart are the lever and the cylinder on a Corbin Russwin ML2000 sectional trim?
Center to center, lever to cylinder is 3-5/8 inches (92mm), and lever to thumbturn is 2-7/16 inches (62mm). Those are the numbers that decide whether new trim covers the holes already bored in your door face. The lockcase itself is 5-7/8 x 4 x 15/16 inches of heavy-gauge steel with an 8 x 1-1/4 inch armored front.
9) Can I keep my existing keys and cylinders if I work on a Corbin Russwin ML2000 mortise lock?
The ML2000 runs on new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, so a locksmith can usually pull your current mortise cylinder straight across. Factory standard is a brass 6-pin L4 keyway, 0-bitted, meaning it ships uncut and gets keyed to your system. Note that the 493F34 inside lever itself carries no cylinder; keying lives in the outside trim.
10) How many functions can one ML2000 lockbody be set to, and does the inside lever change with the function?
Twelve functions are configurable from a single ML2054 lockbody, which is why an institution can stock one lockbody and set it for corridor, dormitory, classroom, or storeroom duty. The inside lever is the free side on most of those functions, so the 493F34 in the LW Lustra wrought style covers the inside of the door regardless of how the lock is configured.
11) Is the ML2000 lever trim thru-bolted or just screwed to the door face?
Thru-bolted. The ML2000 trim designs bolt through the door, which holds alignment between the two sides and resists someone pulling the trim off the face. On abuse-prone openings, dormitories and behavioral health among them, that is the difference between trim that stays put and trim that gets levered off. Corbin Russwin also offers Behavioral Health trim (BHSS/BLSS) in the same series when the opening needs ligature-resistant hardware.
12) Can a Corbin Russwin ML2000 be set up for electric latch retraction with access control?
Motorized Electric Latch Retraction (MELR) is available on the ML20900 series version of the ML2000. That is the option for tying a mortise lock into an access control system where the latch pulls back on a credential read. It is specified on the lockbody, not on the lever trim, so the 493F34 inside lever is the same part either way.
