Sargent 578-2 – Frequently Asked Questions

1) What is the Sargent 578-2 spindle kit and what does it actually do in a mortise lock?
The 578-2 is a replacement spindle kit for Sargent 8200 Series mortise locks. The spindle is the square bar that runs through the lock case and carries the turn of the lever or knob into the lock's hub to retract the latch. When a lever goes loose, droops, or spins without pulling the latch back, the spindle assembly is usually what has failed, not the lock body. The kit supplies the spindle assembly components so the existing 8200 case, trim, and cylinder can stay in the door.
2) What does "old style" mean on the Sargent 578-2 spindle kit, and how do I know that is the one my lock takes?
Old style refers to the traditional Sargent spindle design used on earlier 8200 Series mortise locks, and the 578-2 is built to match those existing installations rather than the later configuration. That makes it a match by what is already in the door, not by the lock function code. Pull the existing spindle and compare it to the kit before you commit the door: if your 8200 case takes the newer spindle arrangement, the old style kit is the wrong part. The 7800/8200 Mortise Lock Catalog is the reference for identifying which generation of case you have.
3) Will the Sargent 578-2 spindle kit work in a Sargent 7800 Series mortise lock?
The 578-2 is specified for Sargent 8200 Series mortise locks. Sargent publishes the 7800 and 8200 together in one mortise lock catalog because they share a platform, but the kit's stated fit is the 8200 Series, so treat a 7800 case as an identification job first: match the existing spindle against the kit rather than assuming the family carries across. If the lock in the door is not an 8200, verify against the 7800/8200 Mortise Lock Catalog before ordering.
4) Does the Sargent 578-2 spindle kit come with the levers, roses, or a cylinder?
No. The 578-2 is the spindle assembly only, sold as a replacement part for 8200 Series mortise locks. Levers, knobs, roses, escutcheons, and cylinders are ordered separately. For a repair that is the point: you are reusing the trim and keying that are already on the door. If the trim itself is damaged, order the trim as its own line item.
5) I manage a building with Sargent 8200 mortise locks on every door. Can I stock the 578-2 as a standard repair part?
That works only if the openings are consistent. The 578-2 matches the old style spindle configuration on 8200 Series locks, so a building whose locks all date from the same generation can carry it as a standard shelf item and repair loose levers without pulling cases. Buildings that have been re-hardwared piecemeal will have a mix of spindle configurations, and one part number will not cover the whole fleet. Pull the spindle out of two or three doors at opposite ends of the building before you buy a case of them.
6) Is the Sargent 578-2 spindle kit rated for commercial door traffic, or is it a residential part?
Commercial. The 578-2 is a Sargent 8200 Series mortise lock component, and mortise locks in that class go into office buildings, schools, healthcare facilities, retail, industrial buildings, multi-tenant residential, and government work. It is a repair part for a commercial-grade lock, not a residential tubular-lock accessory.
