Dormakaba 501138-LK – Frequently Asked Questions

1) Is the Dormakaba 501138-LK handed, and what happens if I order the wrong hand?
Handing matters on this one. The 501138-LK self aligning mechanism is built for the inside lever on a left-hand door, so it is not interchangeable with a right-hand assembly. Verify the hand of the door from the inside face before ordering, because the mechanism is made to fit LH geometry without modification.
2) Does the Dormakaba 501138-LK include the lever itself, or just the mechanism?
The 501138-LK is the self aligning mechanism for the inside lever position, supplied as a replacement lock trim component rather than a complete lockset. It goes into an existing Dormakaba mechanical lock assembly, so you keep the lock body and the rest of the trim.
3) My inside lever on a Dormakaba lock sags and won't return level. Is this the part that fixes it?
That is exactly what a self aligning mechanism addresses. The 501138-LK restores proper lever alignment and smooth mechanical operation on the inside lever of a Dormakaba mechanical lock, on left-hand doors. If the drooping lever is on the outside face, or the door is right-hand, this is not the right part number.
4) Will a Dormakaba 501138-LK work in a Corbin Russwin or Schlage lock?
No. It is a genuine Dormakaba component matched to Dormakaba mechanical lock lines, and lever mechanisms are not cross-brand items. For a Corbin Russwin mortise lock you would be looking at that brand's own trim parts, for example the Corbin Russwin 483F80 outside lever and spindle for the ML2000 Series.
5) Can a Corbin Russwin 483F80 lever and spindle be used in place of the Dormakaba 501138-LK?
No. The Dormakaba 501138-LK is a self aligning mechanism inside lever replacement part made to original Dormakaba specifications for Dormakaba mechanical lock assemblies, so it fits only those parent locks. The Corbin Russwin 483F80 is an outside lever and spindle for the ML2000 Series mortise lock, built for a 1-3/4 inch thick door. Different manufacturer, different lock chassis, and it is the outside trim rather than the inside lever, so it is not an interchange for the 501138-LK.
6) I need to stock lever repair parts for a building full of Dormakaba locks. Do I need both hands?
Yes, plan on two part numbers. The 501138-LK covers left-hand inside lever positions only; right-hand openings take the corresponding right-hand mechanism. Walk the building, count openings by hand, and stock accordingly rather than assuming one part covers the fleet.
7) Is the Dormakaba 501138-LK an OEM part or aftermarket?
OEM. It is manufactured to original Dormakaba specifications as a direct replacement, so the fit and mechanical performance match the original component in the lock assembly. That matters on service work where a non-OEM substitute can change lever feel or cause premature wear.
8) Is there a Grade 1 rated lever trim option if my facility spec calls out a grade?
The Dormakaba 501138-LK is a commercial-grade replacement lock trim component for Dormakaba mechanical locks. If a submittal requires a stated ANSI grade on the trim itself, the Corbin Russwin 483F80 lever and spindle is published as Grade 1 in the ML2000 Series with a Corridor/Dormitory function, which is the part to reference for a graded mortise lock trim. Note that it is outside trim for a different lock family, so it is a spec alternative rather than a drop-in swap.
9) Is the 501138-LK rated for commercial traffic or is it a residential part?
Commercial. It is catalogued and built for commercial-grade duty, which is why it shows up in offices, schools, hospitals, retail, warehouses, multi-tenant residential and government buildings where the lever sees constant use.
