Falcon AE77321-LH 643E – Frequently Asked Questions

1) Is the Falcon AE77321 escutcheon trim handed, and what does the LH suffix mean?
Handing matters on this one. The AE77321-LH is built specifically for left-handed openings, so the lever return and spring cage are oriented for that swing. Stand outside the door: if the hinges are on your left and the door swings away from you, that is left hand. Order the right-hand version for the opposite opening rather than trying to flip this one in the field.
2) What exactly comes in the Falcon AE77321-LH assembly - is the lock body included?
This is trim only, not a complete lock. You get the Broadway lever, the Napa escutcheon plate, and the integrated spring cage that returns the lever. The mortise or lock body, cylinder, and strike are separate. If your existing Falcon MA Series lock body is sound and only the outside trim is worn or damaged, this is the part that restores it.
3) Will the Falcon Broadway lever with Napa escutcheon match my other Falcon MA Series doors?
It will if those openings are also MA Series with Broadway lever and Napa escutcheon trim. The AE77321-LH is the genuine Falcon MA Series trim component, so lever shape and escutcheon outline match factory MA trim. Finish is the other half of the match: this one is 643E Aged Bronze. A door running a different Falcon lever style or escutcheon shape will not look identical, even though it is the same series.
4) My Falcon lever is drooping and won't return level - do I need a whole new lock?
A sagging lever is almost always the spring cage rather than the lock body. The AE77321-LH replaces the outside trim complete with a new integrated spring cage, so the lever returns to horizontal again without pulling the mortise body out of the door. Confirm you have MA Series trim with a Broadway lever, and match the handing (LH here) and the 643E Aged Bronze finish.
5) Can I use the Falcon AE77321-LH on a Corbin Russwin or Schlage mortise lock?
No. This is Falcon MA Series trim and it mounts to MA Series lock bodies. For a Corbin Russwin mortise opening you want that brand's own trim, for example the Corbin Russwin 483F80 outside lever and spindle for the ML2000 Series, a Grade 1 corridor/dormitory trim for 1-3/4 inch doors. Mixing trim across mortise brands does not line up on spindle and mounting prep.
6) Can a Corbin Russwin 483F80 lever and spindle be used to repair a Falcon MA Series opening instead of the AE77321-LH?
No. The AE77321-LH is Falcon MA Series lock trim - a Broadway lever with a Napa escutcheon assembly and integrated spring cage, built as a genuine Falcon replacement part for MA Series hardware. The Corbin Russwin 483F80 is an outside lever and spindle for the Corbin Russwin ML2000 Series, sized for a 1-3/4 inch thick door. The two belong to different manufacturers' mortise platforms, so the 483F80 will not fit MA Series trim. Match the MA Series part to MA Series hardware.
7) What finish is the Falcon AE77321-LH, and what does 643E look like next to other bronze hardware?
Aged Bronze, BHMA finish code 643E, applied at the factory. It reads as a warm, darkened bronze rather than a bright polished tone. If the rest of your openings are specified 643E you are matching exactly; a satin bronze or oil-rubbed finish from another line will not be a direct visual match.
8) Is the Falcon AE77321-LH suitable for a high-traffic commercial door, or is it residential trim?
It is commercial-grade trim, catalogued for commercial use and built to Falcon's MA Series standards for offices, schools, healthcare, retail, government buildings, multi-tenant residential, and warehouse facilities. The spring cage is the part that matters for traffic: it carries the lever return load so the lock body's own spring is not doing that work, which is why worn trim shows up first on busy doors.
9) My door is right-handed - can I use the AE77321-LH and flip it?
No. The AE77321-LH is built specifically for left-handed applications so it aligns and functions correctly without field modification, and it should not be reworked to the opposite hand. Order the right-handed MA Series Broadway/Napa trim instead. Note that hand is not always called out the same way on other platforms - the Corbin Russwin 483F80, for example, is described by door thickness (1-3/4 inch) and ML2000 Series fit rather than by hand.
10) Is the Falcon AE77321-LH an aftermarket copy or a genuine Falcon part?
Genuine Falcon. It is the OEM MA Series trim component, so lever profile, escutcheon footprint, and finish are the factory ones rather than a look-alike. For a facility standardizing on Falcon MA hardware, that keeps replacement doors identical to the rest of the building.
