Sargent 82-0168 – Frequently Asked Questions

1) What exactly is the Sargent 82-0168 and what does it do inside the lock?
The 82-0168 is a classroom hub, an internal replacement part Sargent builds for thumbturn cylinder configurations in commercial mechanical lock assemblies. The hub geometry is what lets the interior thumbturn drive classroom function. It is a component inside the lock, not a complete lock, cylinder, or trim kit, so you are buying it to repair an existing Sargent assembly rather than to build a new opening.
2) Will the Sargent 82-0168 hub work in a non-Sargent lock body?
No. The 82-0168 is a genuine Sargent component made to OEM specification for compatible Sargent lock assemblies. It is not a universal hub, so it will not drop into a Corbin Russwin, Schlage, or Falcon lock body. If the chassis in the door is another brand, you need that maker's own repair part.
3) I need to replace a worn cylinder, not a hub. Is this the right part?
No, and this is the most common mix-up on the 82-0168. It is the classroom hub that the thumbturn works through, not the keyed cylinder itself. For a Sargent knob or lever cylinder replacement, the Kaba Ilco 1579 Series knob and lever cylinder is made for Sargent. Order the hub only when the failure is in the thumbturn action rather than the key plug.
4) Can a Kaba Ilco 1579 cylinder be used instead of the Sargent 82-0168 classroom hub?
No. The Sargent 82-0168 is a classroom hub, an internal replacement part for thumbturn cylinder configurations inside a Sargent mechanical lock assembly, not a keyed cylinder. The Kaba Ilco 1579 is a knob and lever cylinder built for Sargent locks, so it replaces the keyed plug the user's key enters. If the key turns but the classroom function is not engaging the latch correctly, the hub is the part in question; if the key itself is the problem, the 1579 is the cylinder side of the repair.
5) Our exit device rim cylinder failed on a classroom door. Is the Sargent 82-0168 the part?
Not for a rim application. The Sargent 82-0168 is an internal classroom hub for thumbturn cylinder configurations in Sargent mechanical lock assemblies. A rim device takes a rim cylinder: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, the Schlage 20-022 is the same cylinder with a horizontal tailpiece cam, and the Corbin Russwin 3070-178 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Match the tailpiece orientation and length to the device before ordering.
6) Is this Sargent hub suitable for a school or hospital door, or is it a residential part?
It is a commercial-grade part, built for high-traffic institutional openings such as classrooms, healthcare facilities, government buildings, and multi-tenant residential corridors. Classroom function is the reason it exists, so schools are the core application.
7) Do I have to disassemble the whole lockset to install the 82-0168?
The hub is engineered as a drop-in replacement for compatible Sargent lock assemblies, so a locksmith is opening the lock case and swapping the part rather than replacing the lock. Keying stays as it is, since the hub carries no pinning and no keyway, and your existing thumbturn and cylinder go back in.
8) Does the 82-0168 come with a thumbturn, cylinder, or keys?
No. What ships is the classroom hub on its own. The thumbturn cylinder and any keyed cylinder are separate items. By contrast, a keyed cylinder purchase such as the Schlage 20-021 rim cylinder ships with 2 keys, but a hub has nothing to key.
9) What is the difference between the Sargent 82-0168 and a mortise cylinder like the Corbin Russwin 1000 series?
They sit in different places in the lock. The Sargent 82-0168 is a classroom hub replacement component that works with thumbturn cylinder configurations in a commercial Sargent lock assembly. The Corbin Russwin CR1000-112 is a Grade 1 mortise cylinder in a 1-1/2 inch length with an A02 straight cam, meaning it threads into the lock case and drives the lock through its cam. A hub does not accept a key and does not thread in, so the two are not interchangeable in either direction.
10) If I want to convert to interchangeable core keying rather than repair a thumbturn, what should I be looking at?
The Sargent 82-0168 is a repair component for thumbturn cylinder configurations and does not change how the opening is keyed. For an interchangeable core program, the BEST 1CB is a 1CB Series interchangeable core cylinder and the BEST 1CDF is a drill resistant patented interchangeable core 7-pin brass 150 Series core. On the full size side, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Those decisions are about key control across a facility, where the hub is strictly about restoring mechanical classroom function.
11) Is there an equivalent classroom hub from Adams Rite or Medeco?
Those brands cover different parts of the door. Adams Rite items such as the 4036 mortise cylinder, a Grade 1 cylinder in the 4036 Series for doors 1/2 inch minimum thickness, and the 4024 and 4025 cylinder pulls for MS1847 deadlock systems are aluminum stile door hardware. Medeco items such as the 1075127 5-pin rim type lazy motion single cylinder are keyed cylinders for handlesets and deadbolts. The Sargent 82-0168 hub is specific to the geometry of the Sargent classroom lock assembly it goes into, so it is a Sargent-only component.
12) How do I order the right quantity of the Sargent 82-0168 for a building full of classroom locks?
The part is sold under the single model designation 82-0168 with no finish, handing, or size options to pick, so a multi-door repair is just a matter of quantity. Count the Sargent classroom thumbturn locks that are failing and order one hub per lock.
