Dormakaba ER7 689 – Frequently Asked Questions

1) What sizes does the Dormakaba ER12 extension rod come in?
Two configurations of the ER12 extension rod are offered: a 12 inch adjustable version with a 8-3/8 inch size, and an 8 inch adjustable version with a 6-3/8 inch size. Both come in 689 aluminum finish. Pick the one whose adjustment range covers the gap you need to close on the exit device assembly.
2) Will the ER12 work on a Von Duprin or Precision exit device?
No. The ER12 is built as a replacement rod for compatible Dormakaba exit device assemblies only. For another manufacturer's device, order that maker's own vertical rod or extension kit; exit device rods are not cross-brand interchangeable.
3) Is the ER12 rod a genuine Dormakaba part or an aftermarket copy?
It is a Dormakaba-manufactured replacement component, sold as a direct replacement within the Dorma door closer parts and accessories program. That matters when a facility standardizes on Dormakaba exit hardware and wants the original fit rather than a generic rod.
4) What finish is the ER12 extension rod, and will it match aluminum storefront exit hardware?
Both ER12 rods are supplied in 689 aluminum, the standard painted aluminum finish used across commercial exit device and closer hardware. On an aluminum storefront or a door already fitted with 689 hardware it will blend in; if the existing device is a plated finish such as bright brass, the rod will not match visually.
5) Why would I need an adjustable extension rod on an exit device instead of a fixed one?
An adjustable rod lets you dial in length on site rather than ordering an exact fixed dimension, which is what you want when door height, rail position, or an existing prep does not match the original rod. The ER12 is built that way specifically to absorb varying installation setups on compatible Dormakaba exit device assemblies.
6) Is the ER12 rod suitable for a high-traffic school or hospital door?
The ER12 is a commercial-only part, not a residential one, and Dormakaba lists it for offices, schools, healthcare, retail, industrial buildings, multi-tenant residential and government facilities. For an institutional buyer maintaining egress hardware across a campus, it is the OEM rod for those openings.
7) Can a maintenance tech install the ER12 rod, or does it need a hardware specialist?
The rod is meant to drop into an existing exit device assembly, so it is a parts swap rather than a new install, but Dormakaba specifies professional installation by a qualified door hardware technician. On a fire exit opening that is the right call anyway, since the device has to relatch and operate correctly when you are done.
