Sargent 05-0028 – Frequently Asked Questions

1) What does the Sargent 05-0028 cylinder retainer lever actually do inside a mortise lock?
The 05-0028 is the small lever inside a Sargent 6500 Series mortise lock body that holds the cylinder in place. It engages the groove on the cylinder shell and keeps it seated and aligned so the cam stays in the right relationship with the lock mechanism. If it is broken, worn, or missing, the cylinder can back out or spin and the lock stops operating reliably.
2) Will the Sargent 05-0028 retainer fit any Sargent mortise lock, or only the 6500 Series?
It is made for the Sargent 6500 Series mortise lock only. It is an OEM part cut to Sargent's own dimensions for that lock body and drops in without modification. If the case you are servicing is a different Sargent mortise series, order the retainer specific to that case rather than this one.
3) My tenant's mortise cylinder keeps turning in the door instead of throwing the bolt. Is the retainer lever the fix?
That is the classic symptom of a failed or disengaged cylinder retainer. The 05-0028 is the part in a Sargent 6500 mortise case that clamps into the cylinder shell groove and stops it rotating. Before ordering, pull the cover and confirm the retainer is the damaged piece and not a stripped cylinder shell or a sheared cam, because the retainer only cures the case-side problem.
4) Can a Corbin Russwin 483F80 lever and spindle be used in place of the Sargent 05-0028 cylinder retainer lever?
No - the two parts do different jobs despite both being called levers. The Sargent 05-0028 is a cylinder retainer lever, an internal component that holds the cylinder in place within a Sargent 6500 Series mortise lock body. The Corbin Russwin 483F80 is an outside lever and spindle for the ML2000 Series, a Grade 1 corridor/dormitory trim part sized for a 1-3/4 inch thick door. One is the handle a person grips, the other is a retaining component inside the case, and they are not interchangeable across the two manufacturers' mortise lock lines.
5) Is this a genuine Sargent part or an aftermarket copy?
Genuine Sargent. The 05-0028 is an OEM Sargent lock part built to the factory's original specifications, so the fit in the 6500 case matches the piece that came out of it.
6) Do I have to take the whole mortise lock out of the door to replace the cylinder retainer?
The 05-0028 is a drop-in replacement, so it swaps into an existing 6500 case without rework or drilling. In practice you still remove the cylinder and open the case to reach the retainer, but no part of the door or the lock pocket is modified.
7) Is the 05-0028 keyed or does it affect my keying at all?
It has nothing to do with keying. The retainer only holds the cylinder mechanically in the 6500 case, so your existing keyway, keying and cylinder length are unaffected. Replace it and the same cylinder and keys go back in.
8) Is the 05-0028 rated for high traffic commercial doors or is it a light-duty part?
It is a commercial-grade component intended for high-traffic commercial openings, the kind of service work done in offices, schools, healthcare buildings, hotels and municipal facilities running Sargent 6500 mortise hardware.
9) How many pieces come when I order the Sargent 05-0028?
The 05-0028 is sold as the single retainer lever component, one part number covering the one item. Plan on one per cylinder position, so a double-cylinder 6500 case being fully rebuilt takes two.
