Dormakaba 430 DORMA – Frequently Asked Questions
1) Will the Dormakaba 430-DORMA box strike work with my 9300 Series rim exit device?
Yes. The 430-DORMA rim box strike is the genuine Dormakaba replacement strike made for the 9300 Series rim exit device, and it is intended for that family only. It is the piece the rim latch throws into on the frame, so replacing it restores latching without swapping the whole device.
2) Can I use the 430-DORMA strike with a vertical rod or mortise exit device?
No. This is a rim box strike, which only suits a rim exit device where the latch projects from the face of the device into a strike mounted on the frame stop. Surface or concealed vertical rod devices latch at the head and threshold, and a mortise device uses a frame-mortised strike, so neither takes this part. For those you need the strike specified for that device type.
3) My exit device latch is not catching anymore. Do I have to replace the whole device?
Often not. If the door still pushes and the latch throws, a worn or damaged box strike is a common cause of failed latching, and the 430-DORMA is sold as a direct replacement strike so the existing 9300 Series device stays in place. That is a far smaller job than pulling and re-prepping the device.
4) Is the Dormakaba 430-DORMA an aftermarket part or a factory component?
It is a genuine Dormakaba OEM component from the Dorma exit device parts and trims line, built to the original factory fit and function for the 9300 Series. If you are standardizing spares across a building, ordering OEM keeps every opening on the same strike.
5) Is this strike suitable for a high-traffic commercial opening, or is it a residential part?
Commercial. The 430-DORMA is a commercial-grade exit device part, the kind used on office buildings, schools, hospitals, retail, warehouses, multi-tenant residential and government buildings where the exit device sees constant use.
