Sargent 97-0042 – Frequently Asked Questions

1) What is the Sargent 97-0042 and what does it actually do in the door hardware?
The 97-0042 is a knob hub, a genuine Sargent OEM replacement component that carries the knob and transfers its rotation into the device it is mounted on. It is a repair part, not a complete trim or lock, so it goes into an existing Sargent assembly to restore proper knob engagement and operation rather than being installed on a bare door.
2) Will the Sargent 97-0042 knob hub fit exit devices from other brands like Von Duprin or Precision?
No. The 97-0042 is built to Sargent's original specifications for Sargent exit device and mechanical lock assemblies. Knob hubs are machined to a specific spindle and trim interface, so it is not a cross-brand part. If the device on your door is not a Sargent, source the hub from that manufacturer's parts list instead.
3) Is the Sargent 97-0042 knob hub a commercial part or will it work on residential door hardware?
It is a commercial part. Sargent lists the 97-0042 under commercial door hardware, and it is intended for Sargent exit device and mechanical lock assemblies of the kind used in offices, schools, hospitals, retail, warehouses, multi-tenant residential buildings and government facilities. Residential knob sets from other makers will not take it.
4) Do I have to replace the whole exit device trim, or can I just swap the knob hub?
If the failure is in the hub itself, the 97-0042 is meant to go in as a direct drop-in replacement so the rest of the existing Sargent hardware stays on the door. That keeps the opening out of service for a lot less time than pulling and re-prepping a full trim. Confirm the hub is the worn component before ordering, since a sloppy knob can also come from a failed spindle or the device chassis.
5) How is the Sargent 97-0042 sold, and what do I get for one order?
The 97-0042 is sold as a single knob hub under one SKU, with no finish or size options to specify. Facilities standardizing on Sargent hardware usually stock a few for the openings that see the most traffic, since the part number is the only identifier needed to reorder.
