Dormakaba 431 DORMA – Frequently Asked Questions

1) What exactly is the Dormakaba 431-DORMA part, and what does it do?
The 431-DORMA is the recessed bottom strike that the Pullman latch on a Dormakaba exit device drops into at the floor. It is the floor-side half of the latching, not part of the device itself, so it is what you replace when the latch no longer catches cleanly at the sill or the old strike pocket is worn or damaged. It mounts flush into the sill or floor surface rather than sitting proud of it.
2) Will the 431-DORMA bottom strike work with my Dormakaba exit device?
It is specified for Dormakaba 91 Series and 9400 Series exit devices using the Pullman latch. If your device is one of those two series and bottom-latches with a Pullman latch, this is the matching strike. If your opening uses a different Dormakaba series, or a surface vertical rod device with a standard bottom rod and floor strike rather than a Pullman latch, this is not the right part.
3) Is the Dormakaba 431-DORMA a genuine OEM part or an aftermarket copy?
It is a genuine Dormakaba OEM replacement component, made to Dormakaba's own specifications for the 91/9400 Series latch assemblies. For a maintenance shop standardizing on OEM parts, that matters: the strike pocket geometry has to match the Pullman latch throw exactly or the latch either binds or sits loose.
4) Is a recessed bottom strike a trip hazard in a corridor or exit path?
No. The recessed design sets the strike flush into the sill or floor, which is the reason it is used on exit paths in schools, hospitals and office corridors instead of a surface-applied floor strike. Surface strikes stand above the finished floor and are the ones that catch carts and toes.
5) My Pullman latch is no longer holding the door tight at the bottom. Is the strike the problem?
Often yes. On a 91 or 9400 Series device the Pullman latch depends on the bottom strike pocket to capture and hold it; once that pocket is worn, deformed by a dragging door, or packed with debris and grit from floor cleaning, the latch engages shallow and the door rattles or pops. Swapping in the 431-DORMA recessed strike restores the original engagement without touching the device head or the rod.
6) Does the 431-DORMA come with the Pullman latch or any other device parts?
No. It is the bottom strike on its own, ordered as a single replacement component. The Pullman latch, rods, device chassis and trim are separate parts, so if the latch itself is damaged as well as the strike pocket you will need to source that piece too.
7) Can I use the 431-DORMA strike in a residential building?
It is a commercial-duty part built for high-traffic openings, and it only fits Dormakaba 91 and 9400 Series exit devices. Those devices show up in multi-tenant residential buildings on stair and service doors, so it has a place there, but it is not a fit for any residential entry lock or standard bored lockset.
8) Are there different sizes or finishes of the 431-DORMA to choose from?
No options to specify. The 431-DORMA recessed bottom strike is ordered as one part number, model 431 DORMA, with no size, hand or finish selection to make.
