Quick Verdict

Sargent door hardware sorts into four families, and the model number tells you which. 80 Series (8800, 8700, 8600, AD8400, 8900) are Grade 1 exit devices, and the 700 series are their trims. 8200 is the Grade 1 mortise lock. 10X and 11 Line are the cylindrical (bored) locks. 351 and 1431 Powerglide are the surface closers. Order by three things: the family, the function or arm package suffix, and the keyway (LA is the standard Sargent keyway on the parts in this guide). For electrified work, the 56- prefix means electric latch retraction and the 55- prefix adds a non-contact request-to-exit switch. Cores and cylinders ride along with the device: #41 mortise, #34 rim, 6300 LFIC.

What are the Sargent 80 Series exit devices and which trim goes with each?

The 80 Series is Sargent's Grade 1 exit device line, certified to ANSI/BHMA A156.3 and listed UL10C (fire) and UL305 (panic). The first digits after the 8 are the channel: 8800 is surface rim, 8700 is surface vertical rod, 8600 and AD8400 are concealed vertical rod, 8900 is mortise. For what each channel does on the door, read the rim vs SVR vs mortise vs CVR breakdown once and stop guessing from the picture.

The last digit is the trim function: 0 is exit only with no trim (8810, 8910, AD8410), 4 is night latch (8804), 6 is storeroom (8806). The same rail therefore shows up as 8810 on a back-of-house door and 8804 on a retail entrance.

Check the rim line against the opening. The 8810 Grade 1 rim exit bar needs a 1-3/4" minimum door thickness and a 4-1/2" minimum stile. The device is non-handed. Length codes are E (32", for 24" to 32" doors), F (36"), J (42") and G (48"), and no cutting is required at those four sizes. The latchbolt has a 3/4" throw and the standard strike is the 649. Hex key dogging is standard on non-fire-rated devices. The 8910 mortise version is for metal doors only and takes a C908 strike.

Trims through-bolt to the chassis. The Sargent 8804 ETB rim exit device with 704 ETB night latch lever trim is the common retail entrance order: key retracts the latchbolt, B lever, rim cylinder in LA keyway, about $2,155 at NLS. For a stockroom or utility door, the 706-8 ETL storeroom trim is the right part: key unlocks the trim, the trim relocks when the key comes out, and it takes a #41 mortise cylinder in LA keyway. It fits 8500, 8800 and NB8700 series devices. The 713-8 classroom trim is the other one you will see on schools. Lever style (L or B), handing (RH or LH) and finish are separate order fields on every trim. For function logic across brands, see how to choose exit device trims. The numbers 8800, 8400, 8600 and 8700 also appear on another brand's devices, so check the Adams Rite exit device guide if the nameplate is missing.

On aluminum storefront doors the device is a narrow-stile concealed vertical rod, and the AD8410 is the one buyers search by name. It is a Grade 1 CVR, exit only, with a 1-3/4" minimum stile, a hollow stile with at least 1-3/8" inside dimension, concealed rods and a 640 strike kit for top and bottom.

Which 8200 mortise function do I order: 8204, 8205, 8259 or 8270?

The 8200 is a Grade 1 mortise lock (ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1), UL cycle tested at 16 million cycles. Every body has the same envelope, so the choice is function, not fit. The door is 1-3/4" thick, the backset is 2-3/4" only, the front is 8" x 1-1/4" prepared to ANSI/BHMA A156.115 (or A156.115W), the minimum stile is 4-1/2" (4-3/4" for electrified functions), and the lock is field reversible. Warranty is 10 years mechanical, 2 years electrified.

Two functions have facts we can state outright. The 8259 double locking mortise lock (conventional cylinder) lets a key from either side lock and unlock both trims, retract the latchbolt without unlocking the trims, and carries an auxiliary deadlatch. The 8270 electrified fail safe mortise lock is the one for access-controlled doors: power on locks the outside lever, power off leaves it free, a key outside still retracts the latchbolt, the inside lever always retracts it. It ships with a Large Format IC core prep, less core, at about $1,165 at NLS. 8204, 8205, 8237 and 8215 are other function numbers on the same lock body; take the function line from the spec sheet or the existing lock nameplate, not from memory, because a wrong function number is a return.

The prep is ANSI A156.115 for a standard cutout (the usual "sargent 8204 template" question). Replacement lockbodies, trim, strikes and cylinders go through Sargent 8200 parts and accessories. For a head to head against other mortise locks, see the 8200 vs L9000 vs ML2000 comparison.

What are Sargent 10X and 11 Line locks?

10X and 11 Line are Sargent's cylindrical locks: bored prep, lever or knob, installed where a mortise is overkill. 10XG04 is the number people search most. NLS carries the 11 Line in Sargent 11 Line Grade 1 locks. Pull the exact number from the old lock's label and confirm finish and handing at the commercial desk. We do not publish a function chart here that we cannot back with a product page.

Which 351 Powerglide package do I need: UO, UH, CPS or 1431-PS?

The 351 is a Grade 1 closer (ANSI/BHMA A156.4), UL 10C listed for positive pressure fire tests, UL/cUL listed for fire-rated doors, with a 30-year limited warranty. One body does every application: it is non-handed, has a 1-1/2" piston, and the spring size adjusts from 1 through 6 (it leaves the factory at size 3). The suffix picks the arm package, and the arm package is the whole purchase decision. The arm type and mounting guide covers how the arms behave, so here is only the suffix map.

• 351-UO: universal standard arm, tri-mount (regular, top jamb or parallel). Sargent 351-UO Powerglide, about $531 at NLS.
• 351-UH: the same universal package with a hold-open arm.
• 351-CPS: heavy-duty forged steel parallel arm with a built-in compression stop from 85° to 105°, 105° maximum opening, dead stop within 3°.
• 1431-PS: heavy-duty parallel arm, 11-1/4" forged steel arm, positive stop from 85° to 110°, 110° maximum opening, on the 1431 body (rated above 15 million cycles).

For narrow top rails, the 351D drop plate lets a parallel arm 351 mount on a door with a top rail as narrow as 3" (more if you pair it with an overhead stop). It is not handed and ships with its screws. Arms, brackets, covers and valves are listed under Sargent door closer parts.

How do 55-, 56- and M56A electrified options work on Sargent exit devices?

This section identifies parts and does not cover wiring. The 56- prefix on an 80 Series device (56-8804 ETL, for example) means motor-driven electric latch retraction: the latch pulls back on a signal so an authorized user can push through. The 55- prefix adds a non-contact request-to-exit switch (a signal switch that reports the touchpad state). Retrofit kits exist for devices already on the door: the M56A motor kit retrofits a standard mechanical rail on 80 Series and P Series devices made after 2006 and contains ribbon wiring, a motor bracket assembly and a motor controller. The 55-M56A kit adds the signal switch, and the 55-R56A kit combines the motor bracket and the push rail assembly.

The "mfg after 2006" wording matters: check the date on the existing rail before you order a kit.

Prefix / suffix	Meaning	Order with it
56-	Electric latch retraction (motor driven)	Power supply sized for the motor, plus the controller from the kit
55-	Adds non-contact request-to-exit signal switch	A controller or access panel that reads the switch
M56A	Motor kit for retrofit on 80 Series and P Series, made after 2006	Existing mechanical rail, kit includes ribbon wiring and controller
AD	Narrow stile (aluminum door) concealed vertical rod, as in AD8410	640 or 639 strike kit, trim for the outside function
ETL / ETB	ET trim plate with L lever or B lever	Cylinder, handing and finish for the lever

Match supply to device in the electronic power supply category.

Which cylinders and cores go with Sargent devices?

Order the cylinder with the device. Three part families cover almost every request.

The #41 mortise cylinder (Sargent 41 1-1/8" 6-pin mortise cylinder) is solid brass, 1-5/32" diameter, 6-pin, supplied with two nickel silver keys and the standard offset cam 13-0664 when ordered without hardware. A 41 is what the 706-8 storeroom trim takes. The #34 rim cylinder (27/32" screw pattern for through-bolted Sargent exit devices, 6-pin, LA keyway) is the cylinder behind a night latch trim such as the 704.

The 6300 is the Large Format IC core: Sargent 6300 6-pin LFIC, about $71 at NLS, with two change keys, supplied in 6-pin, available across keyway families A, B, C, G, H, K, L, N, R and V. The control key (6272 CTL) is a separate order. If you are unsure between SFIC and LFIC for a retrofit, SFIC vs LFIC explained settles it.

Key blanks follow the keyway and the key section: 6270 for multi-keyway composite sections, 6275 for single sections, 275 for 5-pin single keyway. The full matching logic lives in commercial key blanks by brand; do not buy a blank until you know the keyway stamped on the old key or plug.

Common mistakes when ordering Sargent hardware

1. Ordering a device from the trim number alone. The trim (704, 706-8, 713-8) names the function. The device (8800, 8700, AD8400) names the channel. You need both, plus size, handing and finish.
2. Ignoring the stile width. The 8810 and 8804 need a 4-1/2" minimum stile. On a narrow stile aluminum door, an AD8410 is the part, not a trimmed-down rim device.
3. Buying a closer without the arm package. A bare 351 is not a complete order. UO, UH, CPS and 1431-PS differ by arm, not body.
4. Missing the top rail on a parallel arm job. A 3" minimum top rail is required for the 351D drop plate. Measure before you order.
5. Assuming an 8200 backset is adjustable. The backset is 2-3/4" only, and the door must be 1-3/4" thick.
6. Ordering an M56A kit for an older exit device. The kit lists devices made after 2006. Confirm the date on the existing rail.
7. Skipping the cylinder. Trim, mortise lock or rim cylinder, core and control key are separate lines. Strikes are separate too (see the strike plate guide).

FAQ

What does the 8 mean in Sargent 8804 and 8810? It marks the 80 Series. The 88 pair is the surface rim channel and the last two digits are the function: 04 is night latch, 10 is exit only.

Is the Sargent 351 a Grade 1 closer? Yes, it is certified to ANSI/BHMA A156.4 Grade 1, UL 10C listed and UL/cUL listed for fire-rated doors. Ordering a 351 means picking an arm package: UO, UH, CPS and so on.

Can I retrofit electric latch retraction onto an existing Sargent exit device? On 80 Series and P Series devices made after 2006, yes: the M56A motor kit, the 55-M56A with a signal switch, or the 55-R56A with the push rail. Send the existing device model and date to the desk first.

Which Sargent cylinder fits an exit device trim? Mortise trims such as the 706-8 ETL take a #41 mortise cylinder in LA keyway. Night latch trims such as the 704 take a rim cylinder, the #34 being the through-bolt pattern for Sargent exit devices.

Does NLS ship Sargent parts same day? Orders placed before 3:00 p.m. EST ship same day by UPS or FedEx, and ground shipping is free at $450 and up.
