Dormakaba 80020 LH – Frequently Asked Questions

1) Does the Dormakaba 80020 LH spindle work on a right-hand door?
No. The 80020 LH is a factory-designated left-hand spindle, so it only fits left-hand center hung, single acting closer applications. On a right-hand opening you need the right-hand version of the spindle instead. Handing on a center hung closer spindle is not reversible in the field.
2) What does the 1-1/8 inch on the Dormakaba 80020 LH spindle refer to?
That is the clearance dimension of the spindle, the spacing it provides between the closer body and the door in a center hung installation. Dormakaba builds these spindles in different clearance dimensions, so the 1-1/8 inch figure is the number you match to the existing closer setup. Pull the old spindle and confirm its clearance before ordering.
3) Will this spindle fit a double acting center hung door closer?
No. The 80020 LH is specified for center hung, SINGLE acting closer configurations. A double acting center hung closer swings both directions and uses different spindle geometry, so this part is the wrong choice there.
4) I have a Dorma center hung floor closer that has stopped closing properly. Is a spindle what I need?
If the closer body still holds fluid and the arm action is intact but the door no longer aligns or drives correctly, a worn or twisted spindle is the usual culprit, and the 80020 LH is the replacement for left-hand single acting center hung units. Match three things before you order: handing (LH), single acting, and the 1-1/8 inch clearance dimension. Any mismatch on those and the spindle will not seat correctly.
5) Is the Dormakaba 80020 an OEM part or an aftermarket copy?
It is a genuine Dormakaba (formerly Dorma) OEM replacement component, built to the original design specification, so it goes in as a like-for-like swap on closers that call for the 80020 LH spindle. For a property manager standardizing on Dorma closers across a building, that means no shimming or adaptation at the pivot.
6) Does the Dormakaba 80020 LH come with a top pivot or any other closer hardware?
It is sold as the spindle alone, a single replacement part. Cement case, cover plate, top pivot and any arm hardware are separate items, so if you are rebuilding a center hung closer rather than just swapping the spindle, order those parts alongside it.
7) Is the 80020 LH spindle rated for high traffic commercial doors?
Yes, it is a commercial-grade part intended for high-traffic door closer service, which is why it shows up in offices, schools, hospitals, retail, warehouses, multi-tenant residential and government buildings. It is not a residential-duty item.
