Sargent 8204-26D – Frequently Asked Questions

1) Is the Sargent 8204 a complete mortise lockset or just the lock body?
It's the lock body only. The 8204 is the mortise case itself, in storeroom/closet function, so levers or knobs, roses or escutcheons, and the cylinder are ordered separately. If you need a lock that arrives with trim on it, look at a complete set like the Cal-Royal NM8080 storeroom mortise lockset or the Corbin Russwin ML2003 classroom lockset instead. Ordering the body alone is normal when you already have Sargent trim on the opening and only the case has failed.
2) What does storeroom function mean on a Sargent 8200 mortise lock, and is it the right function for a supply closet?
Storeroom/closet is the standard choice for a supply or storage room. The outside lever is always locked and releases only with a key; the inside lever always retracts the latch for free egress, and the door relocks the moment it closes, so nobody can leave it unsecured by accident. It's a single-cylinder, keyed function, so only the outside gets a cylinder. If you need the door to stay unlocked during working hours, storeroom is the wrong function and an office or entrance function is what you want.
3) Will a Sargent 8204 mortise body fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
That's exactly the prep it's built for: 2-3/4 inch backset and 1-3/4 inch door thickness, which is the standard commercial door and the standard commercial backset. If your existing mortise pocket was cut for a 2-3/8 or 2-1/2 inch backset, this body won't line up, the spindle and cylinder holes land in the wrong place. Baldwin's 6310 storeroom mortise body, for instance, is a 2-1/2 inch backset case, so those two are not interchangeable in the same door.
4) Will the Sargent 8200 latchbolt catch my existing ANSI strike, or do I need a new one?
The latchbolt throws 3/4 inch, which is the normal commercial mortise throw, so it engages a standard ANSI 4-7/8 inch strike lip without cutting new frame prep. Where it goes wrong is gap, not throw: if the door-to-frame clearance has opened up past the point where 3/4 inch of bolt still sits behind the strike lip, the door will feel latched and push open. Check the gap before you decide the old strike is fine.
5) Do I have to order a Sargent 8204 mortise body left hand or right hand?
No handing to specify. The 8200 body is field reversible, so one part covers all four hands and you set it at install. That matters for stock: a property manager or a maintenance shop can keep a couple of bodies on the shelf and drop them into any opening in the building rather than stocking a left and a right. The BEST 45H series body is field reversible the same way if you're cross-shopping.
6) Can I use a Sargent 8204 mortise lock on a fire rated door?
Yes. The 8200 series is UL 10C fire rated up to 3 hours and compliant with NFPA 80, so it's usable on a labeled opening up to a 3 hour rating. Storeroom function also keeps the inside lever free at all times, which is what the egress side of a fire door assembly needs. Among comparable mortise locks, the Schlage LE series and the ENGAGE LEMD carry a 3 hour rating as well.
7) Will the Sargent 8200 mortise body work with our existing master key system?
It takes a Sargent cylinder and works across all the Sargent key systems, Degree, Signature, KESO and XC, in either 6 pin or 7 pin. So if your building is already keyed in a Sargent system, this body keys straight into the existing hierarchy. It is a single cylinder function, outside only. If your site is keyed in a different manufacturer's system, you'll be looking at a cylinder solution to match, not at this body's own keying.
8) Is an electronic mortise lock an alternative to the Sargent 8204 body?
The Sargent 8204 body is a mechanical, non-electronic lock, though the 8200 platform does offer electromechanical versions running 12 to 24VDC with EcoFlex technology. If the opening is going on an access control system instead, the BEST 45HW is a heavy duty wired electromechanical mortise lock with 12V/24V operation, and the Command Access ML190 is a heavy-duty storeroom-function motorized mortise lock with field selectable EL/EU operation on 24VDC. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock in corridor function, keyed outside, with request to exit, at 12/24VDC for 1-3/4 inch doors. These all need power to the door and a transfer hinge or power transfer device; the 8204 body needs neither.
9) What is the closest Grade 1 storeroom mortise lock to the Sargent 8204 mortise body?
The Sargent 8204 body is a Grade 1 storeroom/closet mortise lock body. Two peers land on the same grade and function: the Accentra 8805FL, a Grade 1 storeroom mortise lock from the 8800 Series supplied with the Arcadia lever, and the Cal-Royal NM8080, a Grade 1 storeroom mortise lockset rated for 1-3/4 inch doors with an interchangeable core option. The Sargent 8204 is the lock body itself, so lever and rose or escutcheon trim is selected separately; the Accentra and Cal-Royal units are supplied as complete locksets with trim. A locksmith standardizing a building on one keyway will also want to weigh that the 8200 body accepts all SARGENT key systems including Degree, Signature, KESO and XC in 6 or 7 pin.
10) What mortise locks look like a substitute for the Sargent 8204 body but are not?
Several mortise parts sit near the 8204 without doing its job. The Schlage L0170 is a Grade 1 heavy duty mortise half dummy trim in dummy function for 1-3/4 inch doors, and the Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are dummy mortise entrance locksets: dummy trim has no latch and no locking, so it cannot secure a storeroom. The Kaba Ilco 185 Series is a no-handing mortise deadbolt, which throws a bolt but gives no latching or lever operation. The Schlage PC10 is a Grade 1 passage cylindrical lock with rose for 1-3/4 inch doors, and it takes a bored cylindrical prep rather than the mortise pocket the 8200 body requires. The Baldwin 6310 entry/storeroom mortise bodies run a 2-1/2 inch backset against the 2-3/4 inch backset of the 8200 body, so the door prep does not line up.
11) Is the Sargent 8200 mortise lock Grade 1, and how many cycles is it tested to?
Grade 1 and heavy duty, with UL testing to 16 million cycles (verification ID V584148). For a facility standardizing hardware, that cycle count is the argument for a mortise case over a cylindrical lock on high-traffic openings like a main corridor or a stockroom that gets opened hundreds of times a day. Grade 1 is the top ANSI/BHMA durability tier and is what most institutional specs call for on public-side doors.
12) Should I replace a failed mortise lock with a new body, or swap to a whole new lockset?
If the door pocket, trim and cylinder are all still good, replacing the case alone is the cheaper and faster job, and the 8200 body drops into a standard 2-3/4 inch backset, 1-3/4 inch door prep. Swap the whole set when the trim is damaged, when you're changing function, or when the existing prep is a different backset, Baldwin's 6301 and 6310 bodies are 2-1/2 inch backset, so those openings need a matched body, not a Sargent one. Sargent publishes an installation template for the 7800 and 8200 bodies covering sectional rose and escutcheon trims; pull it before you cut anything.
13) What are the alternatives to a Sargent 8200 storeroom mortise lock from other brands?
Straight mechanical Grade 1 storeroom equivalents: the Accentra 8805FL, an 8800 series Grade 1 storeroom mortise lock with Arcadia lever, and the Cal-Royal NM8080, a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. For a body-only replacement like the Sargent, BEST's 45H series heavy duty mortise lock bodies are the closest parallel, though the ones we hold are public entrance and intruder function rather than storeroom. Note the Accentra and Cal-Royal arrive as complete locksets with lever trim, not as a bare case.
14) Can I standardize one Sargent 8200 body across storeroom, classroom and office doors in my building?
Not with one part number. The 8200 platform covers 56 different functions, including electromechanical, security and monitoring options, but the function is built into the body, and the 8204 is storeroom/closet. What you can standardize is the door prep and the keying: every 8200 body uses the same 2-3/4 inch backset and 1-3/4 inch door prep and keys into the same Sargent system, so a facility can cut one prep and order different function bodies per opening. That's the practical way to spec a building on a single mortise platform.
15) Which mortise lock do I use if the opening needs no key at all?
The Sargent 8204 body is a keyed single cylinder lock, so it is the wrong choice for an opening that never needs to lock. For passage, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating, and the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors. In behavioral health or detention work, the TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, with the MRX-A-01 the arch trim version in satin stainless steel. For privacy on a restroom or bedroom, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a 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 to 2 inches.
16) I want keypad entry on a storeroom door - what replaces a keyed mortise lock?
The Sargent 8204 body is keyed and mechanical, so a code-entry opening calls for a different unit. The Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with 300 user codes in classroom function for doors 1-5/8 to 1-7/8 inches, and the DL2700CR Trilogy T2 is a Grade 1 classroom-function electronic mortise lock with a weatherproof design over the same door thickness range. The BEST 45HZ EZ Series is an electronic keypad mortise lock with key override, and the Accentra NTM623-NR nexTouch Generation 3 is a Grade 1 mortise lock with a capacitive touchscreen keypad, no deadbolt, with cylinder override. Note the Alarm Lock units are built around a narrower door thickness range than the 1-3/4 inch door the 8200 body is specified for.
17) Which mortise lock body compares to the Sargent 8200 body for a field reversible heavy duty replacement?
The Sargent 8200 body is heavy duty with field-reversible handing, which is the same property to look for in a peer body. The BEST 45H Series is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCA Series body covers intruder function at the same heavy duty level. The Falcon MA101 is a Grade 1 heavy duty mortise lock with field reversible operation in passage function. The distinction to hold on to is function: the Sargent 8200 body here is storeroom/closet, so the BEST and Falcon bodies named are reversible in the same way but latch and lock differently at the opening.
18) What Grade 1 mortise lock works on a door thicker than 1-3/4 inches?
The Sargent 8200 body is specified for 1-3/4 inch door thickness. For thicker leaves, the Hager 3800 Series Grade 1 mortise locks carry a 1-3/4 to 2-1/2 inch door thickness range on a 2-3/4 inch backset, matching the backset of the 8200 body: the 3810E is passage with escutcheon, the 3810S is passage with rose, and the 3850E is office function with lever and escutcheon, non-keyed. The Baldwin 6310 entry/storeroom bodies cover 1-3/8 inch and over, and the 6301 entry/apartment bodies cover 1-3/4 inch and over, both on a 2-1/2 inch backset, so the door prep differs from a 2-3/4 inch backset opening.
19) Can I use an RFID or credential mortise lock instead of the Sargent 8204 on a storeroom?
The Sargent 8204 is a keyed mechanical body, so credential access means a different lock. The TownSteel FME-2000 Series is a Grade 1 heavy duty mortise lockset with RFID technology in classroom function for 1-3/4 inch doors, and the FME-4000 Series adds electronic intruder classroom operation with RFID at the same grade and door thickness. The Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile enabled deadbolt with LED in Greenwich trim, right hand, with a 3 hour fire rating. Note the LEMD-GRW is ordered handed, where the 8200 body is field reversible.
20) Is there a fire rated alternative to the Sargent 8200 mortise body for a 3 hour opening?
The Sargent 8200 mortise body is UL 10C fire-rated up to 3 hours with NFPA 80 compliance. Among fire rated peers, the Falcon MA101 is a Grade 1 heavy duty mortise lock carrying a fire rating in passage function with field reversible operation, and the Schlage LEMD-GRW ENGAGE Series wireless mortise lock carries a 3 hour fire rating at Grade 1. The Schlage LEBMB-ADD mobile-enabled mortise lock also carries a 3 hour fire rating for 1-3/4 inch doors at Grade 2 in privacy, office and apartment functions. The 8200 body remains the storeroom/closet option of that group.
21) What mortise lock should I use on an ornamental iron or glass door instead of the Sargent 8200 body?
The Sargent 8200 body is built for a 1-3/4 inch commercial door with a standard mortise pocket, which narrow ornamental and glass openings will not accept. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with a round knob, both specified for 1 inch doors. For a glass door bottom rail, the Kaba Ilco BR Series is a glass door bottom rail lock, and the Alarm Lock DL1300NW Trilogy Networx is a wireless electronic mortise lock with keypad made for Adams Rite deadlatches. The Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile doors.
22) What do I order for a hospital or behavioral health door where the Sargent 8204 lever is not acceptable?
The Sargent 8204 is a lever-style mortise body, and lever trim is what ligature-resistant specifications rule out. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in satin stainless steel, ligature resistant and ADA compliant, from the 195 Series. The TownSteel MRX-A-01 is a Grade 1 heavy duty satin stainless steel ligature resistant arch trim mortise lockset in passage function for 1-3/4 inch doors, with the MRX-L-01 the anti-ligature lever version at the same grade and door thickness. All three are passage function, so they latch without locking, where the 8204 body is storeroom/closet and keyed.
23) What finishes does the Sargent 8200 mortise lock body come in?
Five: 03 bright brass clear coated, 10 satin bronze clear coated, 10B dark oxidized satin bronze oil rubbed, 26 bright chromium plated over nickel, and 26D satin chromium plated over nickel. On a body-only order this matters less than it looks, the case sits inside the door pocket and only the faceplate shows on the door edge. Match the faceplate to the trim already on the door: 26D is the usual commercial default, and 10B is the one to pick if the building is on oil rubbed bronze.
