Corbin Russwin 499F83-8 – Frequently Asked Questions

1) Which door thickness do I order the Corbin Russwin 499F83-8 spindle for?
The 499F83-8 spindle is sold in three door thicknesses: 1-3/8 inch, 1-3/4 inch, and 2-1/4 inch. Measure the actual door leaf, not the frame. Most commercial openings are 1-3/4 inch, which is the standard thickness the ML2000 mortise lock is built around, so that is the one to pick unless you are working on an older interior door (typically 1-3/8) or a thick custom leaf. A spindle cut for the wrong thickness either bottoms out before the lever seats or leaves the lever loose on the hub.
2) What does the Corbin Russwin 499F83-8 actually do inside a mortise lock?
It's the door spindle for the ML2000 Series mortise lockset, the square bar that passes through the lock case hub and carries the turning motion from the lever or knob on one side to the retractor inside the case. It is a replacement component, not a complete lock. If your levers turn but the latchbolt doesn't pull back, or one side operates and the other spins free, the spindle is the usual suspect. You still need the lock case, trim, and rose or escutcheon.
3) Will this spindle fit my Corbin Russwin ML2000 mortise lock, or do I need to know the function first?
It's a genuine ML2000 Series part, so it goes with ML2000 mortise lock bodies. Before ordering, confirm the lock case in your door is the ML2000 family: heavy-gauge steel case measuring 5-7/8 x 4 x 15/16 inches, with a 2-3/4 inch backset and an 8 x 1-1/4 inch armored front. That case size and backset are what separate this line from other mortise locks in a building, and it's a two-minute check with the lock pulled off the door.
4) My ML2000 lever flops and won't retract the latch. Is the spindle the fix, or do I need a whole new lock?
On a lock that otherwise cycles, a worn or sheared spindle is the cheaper fix, and the 499F83-8 is the ML2000 replacement for it. The case itself is heavy-gauge steel and the line is tested to 14.5 million cycles, so the case usually outlives the drive components. If the latchbolt is sticky or the deadbolt won't throw its full 1 inch, that points at the case or the latch assembly instead, and Corbin Russwin lists separate latch assemblies, screw packs, levers, deadbolts, and latchbolts for the ML2000.
5) Can I use the 499F83-8 to repair a mortise lock on a 3-hour fire door?
Yes, so long as you're repairing an ML2000 with genuine ML2000 parts. The series is UL/cUL listed to UL10C positive pressure for 3-hour fire doors up to 4 by 10 feet single and 8 by 10 feet pair. Substituting a generic spindle on a labeled opening is what puts the listing at risk, which is the reason to use the manufacturer's own part number on fire-rated doors.
6) Is the Corbin Russwin 499F83-8 spindle handed, or does one part cover left and right hand doors?
Handing lives in the lock case, not the spindle. The ML2000 uses a patented quick reversible latchbolt that lets you re-hand the lock without disassembling the case, so a single spindle part number works whichever way the door swings. Order by door thickness, which is the only variable you have to get right here.
7) Does replacing the ML2000 spindle affect the cylinder or my keying?
No. The spindle drives the lever, and the cylinder is a separate component sitting 3-5/8 inches center to center from the knob or lever, with a thumbturn position 2-7/16 inches from it. Swapping the spindle leaves your keying alone. The ML2000 takes new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, with a 6-pin L4 keyway brass cylinder shipped 0-bitted as standard.
8) Will an ML2000 repaired with this spindle still latch into my existing ANSI strike?
Yes, if the strike is a standard ANSI straight lip prep. The ML2000 uses a 4-7/8 x 1-1/4 inch strike with 1-1/8 inch lip to center, a two-piece anti-friction latchbolt with 3/4 inch (19mm) throw, and a deadlocking auxiliary latchbolt at 9/16 inch effective throw. The spindle doesn't change any of that geometry, so a repair keeps the same latch engagement you had.
9) Is the Corbin Russwin ML2000 mortise lock Grade 1 for a school or hospital spec?
Grade 1 on both counts. The ML2000 meets ANSI/BHMA A156.13 Series 1000 at Operational and Security Grade 1, and it also carries ADA A117.1, California State Fire Marshal, and windstorm/hurricane certification. One ML2054 lockbody covers 12 configurable functions, which is what lets a facility standardize on a single case across classrooms, offices, and storerooms and stock one spindle part for repairs.
10) I'm standardizing mortise locks across a building. Does the ML2000 spindle come in finishes to match my existing trim?
The spindle is internal hardware, hidden inside the door once the trim is on, so finish matching matters on the levers, roses, and escutcheons rather than here. Corbin Russwin carries several finishes across nearly all ML2000 parts, and the trim range runs from standard sectional and escutcheon designs through Museo, Vineyard, and Behavioral Health (BHSS/BLSS) trim, so a fleet of doors can be matched at the trim level while the spindle stays the same part.
