Dormakaba 501138-K – Frequently Asked Questions

1) Is the Dormakaba 501138-K handed, and can I use it on a left hand door?
The 501138-K is a right hand part only. It is the inside lever self aligning mechanism configured for right hand door applications, so it drops in without field modification on an RH opening. On a left hand door you need the left hand version of the mechanism instead, not this one.
2) What exactly does the Dormakaba 501138-K replace on a lock?
It is the inside lever self aligning mechanism, a service part for Dormakaba mechanical lock trim, not a complete lockset. You would order it when the inside lever on an existing Dormakaba trim assembly has lost alignment or stopped operating correctly, and the rest of the lock body stays in the door.
3) Can a Corbin Russwin 483F80 lever and spindle be used in place of the Dormakaba 501138-K?
No. The Dormakaba 501138-K is a self aligning mechanism inside lever replacement part built for right hand Dormakaba mechanical lock trim assemblies, so it is matched to Dormakaba hardware. The Corbin Russwin 483F80 is an outside lever and spindle for the ML2000 Series mortise lock, sized for a 1-3/4 inch thick door. Different manufacturer platforms and opposite lever positions - inside versus outside - so the two are not interchangeable in the same lock.
4) Is the 501138-K a genuine Dormakaba OEM part or an aftermarket lever?
Genuine Dormakaba, built to Dormakaba specification as an OEM replacement for its own lock trim assemblies. For a facility standardized on Dormakaba hardware, that keeps the serviced trim matching the rest of the assembly rather than mixing an aftermarket lever into it.
5) Do I need to re-adjust the lever after installing the 501138-K?
The self aligning design sets lever position on assembly, so it holds proper alignment and operation without the manual fiddling a non-aligning lever often needs. That is the point of the part: it restores correct lever travel on a trim assembly that has gone out of alignment.
6) I need an outside lever and spindle instead of an inside lever. What else is there?
The 501138-K covers the inside lever position only. If the failure is on the pull side, an outside lever and spindle service part is the correct item. One we carry from another brand is the Corbin Russwin 483F80, a Grade 1 ML2000 Series outside lever and spindle for a 1-3/4 inch thick door in a corridor/dormitory function, though that fits Corbin Russwin ML2000 trim and not Dormakaba hardware.
7) Is the Dormakaba 501138-K rated for commercial traffic the way a Grade 1 mortise lever is?
The 501138-K is specified as a commercial replacement part for Dormakaba mechanical lock trim, intended for high-traffic institutional and commercial openings such as schools, healthcare, and government buildings. If you are comparing against a graded mortise trim part, the Corbin Russwin 483F80 lever and spindle carries a Grade 1 rating within the ML2000 Series. The two serve different lock platforms, so choose based on the lock body you are servicing.
8) Does handing matter when choosing between the 501138-K and a mortise lever and spindle set?
Yes for the Dormakaba part: the 501138-K is built specifically for right hand openings, so a left hand door needs the corresponding left hand version rather than field modification. The Corbin Russwin 483F80 is identified instead by its door thickness of 1-3/4 inch and its Corridor/Dormitory function within the ML2000 Series. Confirm the door hand before ordering the Dormakaba mechanism.
9) Is this lever mechanism rated for commercial traffic or is it a residential part?
Commercial. Dormakaba lists the 501138-K as a commercial-grade component intended for high-traffic institutional and commercial openings, which is where its typical use sits: offices, schools, healthcare, government buildings, retail, warehouses, and multi-tenant residential.
