Sargent 130KB-26D – Frequently Asked Questions

1) Will the Sargent 130KB thumbturn fit a mortise lock from another brand, like a Schlage L Series or a Corbin Russwin ML2000?
No. The 130KB is built to the Sargent 8200 Series mortise lock preparation and its spindle and mounting are specific to that family. It will not drop onto a Schlage L Series, a Corbin Russwin ML2000, or any other manufacturer's mortise case. Mortise trim is not cross-brand interchangeable, so if the case in your door is not a Sargent 8200, order the thumbturn from that lock's own parts list.
2) I need a thumbturn on the inside of a classroom or restroom door. Should I buy the 130KB or a whole new lock?
That depends on what is already in the door. If the door already has a Sargent 8200 mortise case prepped for a turn, the 130KB is the part you want and you keep the existing case and lever. If the door has no mortise lock, or the case is a different brand or does not take a turn, you are buying a complete lockset instead. For privacy on a restroom, a complete Grade 1 privacy mortise lockset such as the Cal-Royal NM8440 or the Hager 3840S covers the function in one order. For classroom, the Cal-Royal NM8070 or Corbin Russwin ML2003 are Grade 1 classroom mortise locksets.
3) Is the Sargent 130KB thumbturn a substitute for a complete privacy mortise lock?
No. The Sargent 130KB is a standard mortise thumbturn for the 8200 Series - a turn piece that gives interior locking control on an 8200 mortise lock, not a lockset with a latch, trim, and case. If the opening needs a complete privacy lock installed as one unit, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch.
4) What is the difference between a Sargent 130KB thumbturn and a Schlage L0170 half dummy trim?
The Sargent 130KB is a working turn piece: it operates the interior locking of a Sargent 8200 Series mortise lock. The Schlage L0170 is a Grade 1 heavy duty half dummy trim in the L Series for 1-3/4 inch doors, a dummy function part that mounts to the door face and does not operate anything. They look similar in a parts list and are not interchangeable - one controls the lock, the other is a pull.
5) The opening needs a keyed lock rather than an interior turn - what mortise locksets cover storeroom and classroom function?
A thumbturn like the Sargent 130KB gives occupant control from inside and does not key the door. For a keyed storeroom opening, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. For classroom function, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch.
6) Can a Sargent 130KB thumbturn be used on a lock body from another manufacturer?
The Sargent 130KB is made for Sargent 8200 Series mortise locks and its fit is to that system. Other mortise bodies are built around their own trim: the BEST 45H is a heavy duty public entrance mortise lock body, the Baldwin 6301 is an entrance and apartment mortise lock body with a 2-1/2 inch backset for doors 1-3/4 inch and over, and the Marks USA 21AC is a 21 Series double cylinder ornamental iron mortise lock for 1 inch doors. Match the turn piece to the lock body brand and series rather than mixing across them.
7) Is the Sargent 130KB thumbturn heavy duty enough for a high traffic commercial door?
The 130KB is rated standard duty and is a commercial part, not residential. That is fine for offices, tenant suites, restrooms, and interior rooms on an 8200 lock. On an opening that gets punished all day, a stairwell or a main corridor, the duty rating is the thing to weigh before you standardize on it across a floor.
8) Does the Sargent 130KB thumbturn have a handing I need to specify?
Finish is the only choice to make on the 130KB. There is no left or right hand version of the thumbturn, so order it in the finish that matches your trim and nothing else needs calling out. Handing is decided by the 8200 mortise case and the lever trim, not by the turn.
9) Can I use a thumbturn instead of a keyed cylinder on the inside of a commercial door?
On the inside face, yes, and that is exactly what the 130KB does on a Sargent 8200 mortise lock: the occupant secures the door by hand without carrying a key. Two things to hold in mind. A thumbturn only works where your building code allows free egress by a single motion, so check the requirement for the room before you swap a cylinder for a turn. And it gives no outside control at all, so the outside face still needs its cylinder or its trim.
10) I want keyless entry on my mortise doors. Is a thumbturn what I need?
Not on its own. The 130KB is a mechanical inside turn, no codes, no credentials, no audit trail. For keyless you want an electronic mortise lock: TownSteel's FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, the Alarm Lock DL3500CR Trilogy is Grade 1 classroom with 300 user codes for 1-5/8 to 1-7/8 inch doors, and the Dormakaba E-Plex 2066 is a pushbutton keyless mortise lock. Those replace the lock, not just the trim.
11) What prep or template do I need to install a Sargent 130KB thumbturn?
The turn mounts into the existing 8200 mortise prep, so a door already carrying an 8200 lock needs no new routing for it. On a fresh install, Sargent publishes an installation template covering the 7800 and 8200 Series mortise locks with all sectional rose trims and escutcheon trims, and that is the sheet you cut the door from. Verify the door thickness and stile against the template before drilling.
12) The interior needs push-button or keypad control instead of a thumbturn - what should be specified?
The Sargent 130KB is a mechanical turn piece for 8200 Series mortise locks in commercial applications. Where the opening calls for coded entry instead, the Schlage CO-100 is a Grade 1 standalone electronic mortise lock in privacy function with a keypad reader for 1-3/4 inch doors, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock in the E-Plex 2000 Series built for wide stile doors. Those are full electronic locksets, so the door prep and power approach differ from a thumbturn swap.
13) Is a thumbturn the same as a mortise deadbolt?
No. The Sargent 130KB thumbturn is the turn piece that operates locking on an 8200 Series mortise lock. A mortise deadbolt is a separate lock body: the Kaba Ilco 185 Series is a deadbolt function mortise lock supplied with no handing, and the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt in deadbolt function with a privacy keypad for doors 1-5/8 inch to 1-7/8 inch. Specify the deadbolt when the door needs its own bolt, and the 130KB when the 8200 lock body is already in the door and only the turn piece is being supplied.
14) The door should not lock at all - what replaces a thumbturn on a passage opening?
A thumbturn adds locking control, so it is the wrong part where the door must stay free. For passage openings, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series with field reversible operation and a fire rating, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock in the PM Series for 1-3/4 inch doors, and the Hager 3810S is a 3800 Series Grade 1 passage mortise lock with rose and a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch.
15) What are the options for a behavioral health or ligature resistant opening instead of a standard thumbturn?
A projecting turn piece such as the Sargent 130KB is a standard duty commercial component. Where the opening calls for ligature resistant trim, the TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the TownSteel MRX-A-01 is the same passage function with satin stainless steel ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel.
