Sargent 10-0842 – Frequently Asked Questions

1) What does the Sargent 10-0842 tailpiece actually do inside a 10 Line lock?
The 10-0842 is the cylinder tailpiece that transfers rotation from the cylinder plug into the 10 Line lock mechanism so the key retracts the latch or bolt. If a key turns freely but nothing moves, the tailpiece is usually the failed link. It is a Sargent OEM part cut to factory dimensions, so it drops into the lock body without modifying the lock or the cylinder.
2) Will the Sargent 10-0842 tailpiece work with a Medeco or Schlage SF cylinder?
Yes, that is exactly what it is for. The 10-0842 is the tailpiece specified for Sargent 10 Line locks built with the Medeco or Schlage SF cylinder options, so if you are swapping in a Medeco high-security cylinder or working a Schlage SF keying system into an existing 10 Line mortise lock, this is the correct interface part.
3) Is this a genuine Sargent part or an aftermarket copy?
Genuine Sargent OEM. The 10-0842 is a factory replacement part made to Sargent's own tolerances, which matters on a tailpiece because a few thousandths of slop shows up as a sloppy or non-functioning key turn. For facilities standardizing on Sargent hardware, it keeps the lock to manufacturer spec.
4) Does the 10-0842 come with a cylinder, or is it the tailpiece only?
Tailpiece only. The 10-0842 is the single drive component that bridges the cylinder plug and the lock mechanism. If you are converting a 10 Line lock to Medeco or Schlage SF keying, you still need to source the cylinder itself, keyed to your system, separately.
5) Is the Sargent 10-0842 suitable for commercial or institutional door hardware?
It is a commercial-grade part, built for the mechanical lock applications you see in offices, schools, healthcare and government buildings running Sargent 10 Line mortise locks. Property managers and MRO buyers stocking spares for a building full of 10 Line hardware with Medeco or Schlage SF cylinders will want this on the shelf.
