Dormakaba 012-508561-K – Frequently Asked Questions
1) What does the Dormakaba 012-508561-K lever torsion spring actually do in a lockset?
It is the return spring for the lever. The torsion spring supplies the restoring force that brings a lever handle back to horizontal after it's released, which is what keeps the latch engaging consistently. When a lever on a Dormakaba mechanical lock starts to droop or feels dead on the return, a failed torsion spring is the usual cause and this is the OEM part number for it, 012-508561-K.
2) Is the Corbin Russwin swivel spindle pin and set screw a substitute for the Dormakaba 012-508561-K lever torsion spring?
No. The Dormakaba 012-508561-K is a lever torsion spring that supplies the restoring force for lever return and consistent latch engagement in compatible Dormakaba mechanical lock assemblies, supplied in a 10-pack. The Corbin Russwin 499F838 is a swivel spindle pin with a set screw, which retains and connects the spindle rather than returning the lever, and it is specified for 1-3/4 inch doors. If the lever is sagging or not returning to horizontal, the torsion spring is the part that addresses it; a loose or disconnected lever-to-spindle joint is what the pin and set screw addresses.
3) How many springs come in the Dormakaba 012-508561-K pack?
Ten. The 012-508561-K ships as a 10-pack, which is how maintenance shops and locksmiths usually buy it, since a lever repair may need one or two springs and the rest go on the shelf for the next service call.
4) I need spindle parts too, not just a spring. What else is out there for lever repairs?
The 012-508561-K covers the lever return spring side of the repair only. If the problem is a loose or spinning lever rather than a weak return, the fastening hardware is the part to look at: ZenSupply also carries the Corbin Russwin Swivel Spindle Pin X Set Screw, listed for 1-3/4 inch doors. That is a Corbin Russwin part, though, so use it on Corbin Russwin locks, not as a substitute inside a Dormakaba assembly.
5) I have a mix of Corbin Russwin and Dormakaba locks in one building - can I stock one spring or pin for both?
No, keep them separate. The Dormakaba 012-508561-K is an OEM torsion spring built to Dormakaba specifications for compatible Dormakaba mechanical lock lever assemblies, and the Corbin Russwin 499F838 is a swivel spindle pin with set screw. They are different functional parts from different lock platforms, so each brand's lever assemblies need its own part. A practical approach is to stock the 012-508561-K by the 10-pack for the Dormakaba openings and order the Corbin Russwin pin separately for 1-3/4 inch Corbin Russwin doors.
6) Is the 012-508561-K torsion spring suitable for commercial door hardware or is it a residential part?
Commercial. Dormakaba classifies the 012-508561-K as a commercial mechanical lock replacement part, intended for high-use openings in offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings.
7) Should I stock the 012-508561-K spring in my parts crib?
It is a sensible stocking item if your building runs Dormakaba mechanical locks. Lever return springs are a wear item on high-traffic openings, and the 10-pack means a tech can fix the lever on the first trip instead of pulling the lock and waiting on a part. Dormakaba lists it as a replacement part in its official Parts and Accessories program.
