Corbin Russwin 437F40 – Frequently Asked Questions

1) What does the Corbin Russwin 437F40 adapter packet actually do?
The 437F40 is a trim alignment (adapter) packet for the Corbin Russwin ML2000 and ML2000HS mortise lock series. It aligns the trim components to the lock case so the levers or knobs sit square and operate cleanly. It is a replacement part, not a lock or a trim set, so you order it in addition to the lock and trim you already have on the door.
2) Will the 437F40 work on a 1-3/4 inch door?
No. The 437F40 packet is configured for 1-3/8 inch door thickness with half working trim. Commercial openings are most often 1-3/4 inches, so check the door before ordering; for a 1-3/4 inch leaf you need the adapter packet matched to that thickness, not this one.
3) What does "half working trim" mean on a Corbin Russwin mortise lock order?
Half working trim means one side of the opening has an operating lever or knob and the other side is fixed or inoperable. The 437F40 packet is set up for that configuration on ML2000 and ML2000HS locks at 1-3/8 inch doors. If both sides of your lock operate, this is not the packet for that function.
4) I'm a property manager with loose, sagging levers on my mortise locks. Is this the fix?
If the lock is a Corbin Russwin ML2000 or ML2000HS on a 1-3/8 inch door with half working trim, and the trim is misaligned to the case, the 437F40 alignment packet is the part that corrects that relationship. If the levers are worn out or the lock case itself is failing, an alignment packet will not fix it, you need the trim or the lock replaced.
5) Is this a genuine Corbin Russwin part or an aftermarket substitute?
It is an authentic Corbin Russwin component, model 437F40, catalogued as a Corbin Russwin lock part for commercial mortise lock service work. For a facility standardized on ML2000 hardware, using the factory packet keeps the trim alignment consistent across openings.
6) Does the 437F40 come as a single kit or do I order parts separately?
It ships as a packet, meaning the adapter pieces for one trim alignment come together under the single model number 437F40. There is one ordering configuration, so there is no finish, handing, or size choice to specify.
