Corbin Russwin 483F80-626 – Frequently Asked Questions

1) Does the 483F80 lever work on a 1-3/4 inch door?
That is exactly what it is cut for. The 483F80 spindle length is sized for 1-3/4 inch (44mm) thick doors, the standard commercial door thickness. On a thicker door the spindle will not reach correctly, and the ML2000 series offers optional thicknesses, so a non-standard door needs the matching thickness part rather than this one.
2) Do I have to order the Corbin Russwin 483F80 lever left hand or right hand?
No handing to specify. The 483F80 lever is field reversible, and the ML2000 lock it mounts to uses a quick reversible latchbolt that re-hands without taking the lock case apart. One part covers both hands, which is why it works as a stocked repair item for a building with doors swinging both ways.
3) What do I get with the 483F80, and do I still need the lock body?
What ships is the outside lever with its spindle, a replacement trim part rather than a complete lockset. No lock case, no cylinder, no strike, no inside trim. Use it when the lever on the corridor side of an existing ML2000 mortise lock is worn, bent, or loose but the case is still good. If the lock case itself is failing, you need the lockbody, not this.
4) Is the 483F80 lever OK to use on a fire rated dormitory corridor door?
Yes on both counts. The ML2000 mortise lock this trim belongs to is UL/cUL listed and UL10C positive pressure rated for 3-hour fire doors up to 4 x 10 feet single or 8 x 10 feet pair, and the trim is set up for corridor/dormitory function. It is also ANSI/BHMA A156.13 Series 1000 Grade 1 for operational and security, and the lever complies with ADA A117.1. Replacing worn trim with the correct series part keeps that rating intact; a substituted knob or off-brand lever does not.
5) Will replacing the lever change my backset or make me redrill the door?
Nothing changes in the door. The 483F80 is trim only, so the opening keeps the ML2000 series 2-3/4 inch (70mm) backset, the 8 x 1-1/4 inch armored front, and the existing ANSI straight lip strike. Centerline spacing stays as prepped too: 3-5/8 inch (92mm) lever to cylinder, 2-7/16 inch (62mm) lever to thumbturn. It swaps onto the prep already cut.
6) What finishes does the Corbin Russwin 483F80 LW lever come in?
Eleven finishes, so it can be matched to whatever is already hanging on the rest of the openings: 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 steel, 630 satin stainless steel, and 722 black oxidized bronze oil-rubbed. For institutional corridor work, 630 satin stainless is the usual standard and the one most existing ML2000 trim will already be.
7) Do I need a new cylinder or new keys when I put this Corbin Russwin lever on?
No. The lever and spindle carry no cylinder, so keying is untouched, and the ML2000 lock works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders. Whatever the door is keyed to now stays keyed that way after the swap.
8) Can I standardize one lever part across a whole building of Corbin Russwin mortise locks?
Largely, yes, and that is the practical reason to stock it. Because the 483F80 is field reversible and the ML2000 lockbody supports 12 functions from a single ML2054 case, one lever and spindle in one finish covers corridor and dormitory doors of either hand across a facility. The two things that break the standardization are door thickness other than 1-3/4 inch and a different trim design such as escutcheon or Behavioral Health trim, which take their own parts.
9) Is a Grade 1 lever like the 483F80 worth it for a high traffic dorm or school corridor?
For traffic that heavy, yes. The ML2000 platform behind this trim is ANSI/BHMA A156.13 Series 1000 Grade 1 for both operational and security, and it was UL cycle tested to 14.5 million cycles. Trim is the part that takes the abuse in a dormitory corridor, so keeping the same Grade 1 series lever on the replacement is what holds that performance rather than dropping to a lighter residential lever.
