Dormakaba 80020 RH – Frequently Asked Questions

1) Will the Dormakaba 80020 RH spindle work on a left-hand door?
No. The 80020 RH is the right-hand spindle for center hung, single acting closers. Handing on a center hung spindle is not reversible, so a left-hand opening needs the left-hand version of the part instead. Confirm the swing from the pull side before you order.
2) What does the 1-1/8 inch clearance on the Dormakaba 80020 RH spindle refer to?
It is the spindle clearance dimension, which sets how the closer spindle spans between the closer body and the door and controls the geometry of a center hung installation. Spindles for this closer family are sold by clearance dimension, so 1-1/8 inch has to match the clearance on the opening you are servicing or the door will not sit or close correctly.
3) Can I use this spindle on a double acting center hung door?
No. The 80020 RH is built for single acting closers, meaning one-directional swing control. A double acting center hung door swinging both ways needs the double acting spindle for that closer, not this one.
4) Is the Dormakaba 80020 RH an OEM replacement part for Dorma closers?
Yes. The 80020 RH is a Dormakaba factory replacement spindle for Dorma door closer assemblies, so it drops into the original closer without adapting or modifying the existing hardware.
5) My center hung door is dragging and not closing fully. Is the spindle the part to replace?
On a center hung single acting closer, a worn or wrong-clearance spindle throws off the alignment between the closer and the door, which shows up as dragging or incomplete closing. The 80020 RH restores the original 1-1/8 inch clearance geometry, so if the closer body itself still holds fluid and controls speed, replacing the spindle is the usual fix. Match handing (RH) and the clearance dimension to what came out.
6) What do I need to know before ordering a Dormakaba center hung closer spindle?
Three things decide the part: the clearance dimension (this one is 1-1/8 inch), whether the closer is single or double acting (this one is single acting), and the handing (this one is right-hand). Get any of the three wrong and the spindle will not set the door correctly.
7) Is this spindle suitable for a high traffic commercial entrance, or is it a residential part?
It is a commercial-duty part. The 80020 RH is part of Dormakaba's commercial door hardware line and is used in office buildings, schools, healthcare facilities, retail, industrial buildings, multi-tenant residential and government facilities.
