Sargent 82-0421 – Frequently Asked Questions

1) Will the Sargent 82-0421 hub fit a Sargent 8200 Series mortise lock case?
Yes. The 82-0421 is an OEM hub made specifically for the Sargent 8200 Series mortise lock case, so it drops into that case without modification. It is not a universal hub, so it should not be used to service other Sargent series or another manufacturer's mortise case.
2) Can I replace just the hub instead of the whole Sargent 8200 mortise lock case?
That is exactly what the 82-0421 is for. A worn or damaged hub can be swapped out on its own, so a maintenance team can restore lever or knob function without buying and re-installing a complete 8200 Series mortise case.
3) Is the Sargent 82-0421 a genuine OEM part or an aftermarket copy?
It is a genuine Sargent component, built to the same standards as the hub originally supplied in the 8200 Series case. For facilities that have to keep hardware performing to the original design, that matters more than the part cost.
4) Is the 82-0421 hub rated for commercial door traffic or is it a residential-grade part?
Commercial. Sargent classifies the 82-0421 as a commercial-grade component for the 8200 Series mortise lock, the kind of lock used on office, school, healthcare, government, retail and multi-tenant openings. It is the correct part for high-traffic institutional doors rather than light residential duty.
5) What does the hub actually do inside a Sargent 8200 mortise lock?
The hub is the internal component the lever or knob spindle engages, transferring handle rotation into the lock mechanism. When a hub wears or breaks, the trim turns but the latch no longer retracts properly. Fitting the 82-0421 restores that connection and returns the 8200 Series case to normal operation.
6) I manage a building standardized on Sargent 8200 mortise locks. Is this the part to stock for repairs?
If the failure is a stripped or worn hub, yes. The 82-0421 is a repair-part-level item for the 8200 Series case, which makes it a sensible stocking item for a portfolio standardized on 8200 mortise hardware. One part number covers hub replacement across those openings rather than ordering complete cases.
