Von Duprin 210K 689 – Frequently Asked Questions

1) What does key locks and unlocks mean on the Von Duprin 210K knob trim?
Turn the key and the outside knob stays locked or unlocked until you key it back, it's a toggle, not a momentary retract. Unlocked, the knob turns and opens the door for anyone; locked, the knob is dead and the door is entry by key or from the inside push bar only. That's different from a night latch trim, where the key only pulls the latch for that one entry and the outside is always secure otherwise. Pick the 210K where you want the door free during business hours and secured after, without anyone touching the exit device. Egress from the inside is never affected.
2) What keyway does the Von Duprin 210K trim use, and can I key it into my existing system?
It uses a Schlage "A" orbit knob with a six-pin "C" keyway, and the cylinder is furnished with the trim. If your facility is already keyed in Schlage C, this drops straight into the existing system and can be master keyed with the rest of your Schlage C openings. If you run a restricted or proprietary keyway instead, the furnished C cylinder is what you'd be swapping out.
3) Do I need to order a cylinder separately with the 210K exit trim?
No separate cylinder purchase, the 210K is furnished with its cylinder, six-pin Schlage "C" keyway. That's different from a lot of exit trim, which ships less cylinder and expects you to supply one, for example the Corbin Russwin VT957ET nightlatch escutcheon and the Dorma YR03R lever trim are both less-cylinder items. If your locksmith is keying the building, plan on rekeying the furnished cylinder rather than buying one.
4) What is the equivalent to the Von Duprin 210K if the door has a Sargent 700 Series exit device instead of a Von Duprin 22 Series?
The 210K is built for Von Duprin 22 Series exit devices, so it will not mount to a Sargent chassis. On a Sargent 700 Series device, the trim is the Sargent 704ET night latch lever trim, a Grade 1 heavy duty trim with field reversible operation. Note the function difference: the 210K is a knob where the key locks and unlocks the trim, so the knob stays retracting or stays secured until the key is turned again, while the 704ET is a night latch, where the key retracts the latch each time and the lever does not otherwise operate the device.
5) I need a keyed lever instead of a knob on an exit device - what are the options?
The Von Duprin 210K uses a Schlage "A" orbit knob, so it is not the part for a lever opening. Keyed lever escutcheon trims include the Tell EDELT53 in entry function and the Tell EDELT80 in storeroom function, both for doors 1-3/8 inch to 1-3/4 inch thick, and the Design Hardware KIL trims for 1000 and 2000 Series exit devices, offered in entry and storeroom functions with a Schlage C keyway flat lever. All of these mount to their own device platforms, not to the Von Duprin 22 Series, so match the trim to the device already on the door.
6) Is the Falcon 510L a substitute for the Von Duprin 210K?
They are both heavy duty exit trims but they answer different openings. The 210K is a knob trim for Von Duprin 22 Series devices, Grade 1 and heavy duty, with the key locking and unlocking the knob. The Falcon 510L is a heavy duty classroom function lever trim for Falcon 24/25 Series devices - a lever rather than a knob, and classroom function, where the key controls the outside lever from the outside only. Because each trim is cut for its own device series, the 510L is the answer when the device on the door is a Falcon 24 or 25 Series, not a swap onto a 22 Series.
7) What do I use instead of the 210K when the outside trim needs to be electrified for access control?
The 210K is a mechanical knob trim keyed with a six-pin Schlage "C" keyway, with no electrical option in the trim itself. For an access-controlled opening, Command Access builds electrified exit trims with 12V/24V operation and fail safe or fail secure options, including the 230L for V96/36/23 Series devices and the ET26, a Grade 1 field reversible electrified trim. On the Falcon side, the 510L-FSA/FSE is an electrified heavy duty lever trim for 25 Series devices. Confirm which device series is on the door before ordering, since each of these is cut for its own platform.
8) What is the difference between the Von Duprin 210K key locks and unlocks function and a night latch trim?
On the 210K, the key locks and unlocks the knob, so once unlocked the knob operates the device until someone keys it back to locked - the state persists. A night latch trim works differently: the key retracts the latch on each use and the handle does not otherwise release the door. Night latch trims in the same product family include the Accentra 121NL, the Corbin Russwin VT957ET nightlatch escutcheon trim in stamped or formed stainless steel for ED5000 Series devices, the Dorma YR03R wide stile lever trim less cylinder, and the Sargent 744 freewheeling trim where the key retracts the latch on 8700 and 8900 Series surface vertical rod and mortise devices. If the opening needs to stay unlocked during business hours, the 210K function is the one that does that.
9) What looks like the 210K but is actually a dummy trim?
Blank escutcheon and dummy trims can look almost identical on the door but do nothing mechanically - they are pull-only with no latch retraction. The 210K family includes a 210DT dummy trim and a 210K-BE knob with blank escutcheon alongside the operating 210K knob. Elsewhere, the Detex 02BN is a dummy S-lever trim with blank escutcheon for Value Series devices, and the Falcon 212L is a blank escutcheon lever trim for 20 Series devices, medium duty. If the outside handle must actually retract the latch with a key, the operating 210K is the part, not a blank escutcheon version.
10) Which exit trims ship with the cylinder like the 210K does, and which come less cylinder?
The 210K has its cylinder classification listed as furnished, and it uses the Schlage "A" orbit knob with a six-pin "C" keyway. Several comparable trims are supplied less cylinder and need one ordered separately to match the facility keyway: the Corbin Russwin VT957ET nightlatch escutcheon trim, the Dorma YR03R wide stile lever trim, the Dexter ED1000T classroom thumbpiece trim, the Dexter ED1500 nightlatch pull plate trim, and the Tell exit device pull trim with cylinder hole. If the building is keyed in Schlage C, the 210K keying matches without a separate cylinder line on the order.
11) Can I add the 210K trim to a 22 Series device that's currently exit only?
Yes. The 22 Series is a modular platform, so a device running with no outside trim, or with a dummy pull, can be converted to keyed knob operation by fitting the 210K. You're adding outside control to the same device rather than replacing it. Verify the door prep for the trim against the Von Duprin 22 Series trims and strikes template for your door type, hollow metal or wood, since an exit-only door may not have the trim holes bored.
12) Do I have to specify handing when I order the 210K exit trim?
No handing to specify. The 210K escutcheon is non-handed, so one part covers left and right hand doors and you don't need to know the swing before ordering. That matters for a property manager stocking spares, one trim number covers every 22 Series opening in the building.
13) Is a knob trim like the 210K the right choice, or should I use a lever?
A knob is the older commercial look and it's still specified where levers get abused or where a building is standardizing on existing knob hardware. Where accessibility drives the spec, lever trim is what most facilities move to, and Von Duprin's 210 family for the 22 Series includes lever and other configurations alongside the 210K. Within the same family you can also go 210NL if you only want key retraction of the latch, 210DT for a pull with no outside operation, or 210K-BE if the knob is wanted with a blank escutcheon and no cylinder in the trim.
14) Is the Von Duprin 210K heavy duty enough for a school or hospital entrance?
Grade 1, heavy duty, with a 10 gauge (2.4 mm) steel escutcheon, which is the construction level specified for high traffic commercial openings. It's a commercial-rated trim, not a light duty product. For comparison among heavy duty peers, the Sargent 704ET is a Grade 1 heavy duty night latch lever trim for their 700 Series, and the Falcon 510L is a heavy duty classroom lever for 24/25 Series devices, but each only fits its own device family.
15) I need electrified outside trim on a Von Duprin device, will the 210K do that?
The 210K is mechanical, key locks and unlocks by hand. For access control on a Von Duprin device you want electrified trim: Command Access makes the 230L, an electrified version of the Von Duprin 230L trim with 12V/24V operation and fail safe or fail secure selection, for V96/36/23 Series devices. Check your device series against that before ordering, an electrified trim built for one Von Duprin family isn't interchangeable with another.
16) Is there a heavy duty alternative to the 210K if the trim keeps getting vandalized and I want a storeroom function?
The 210K is a Grade 1 heavy duty trim with a 10 gauge (2.4mm) steel escutcheon, and the knob is locked and unlocked by key. If the opening should instead stay locked at all times with the key always retracting, storeroom function heavy duty trims include the Pamex E9000 with an L3 lever, Grade 1, for doors 1-3/8 inch to 2 inch thick, and the Marks USA M195F lever and rose trim with spring loaded roses for the M9900 touchbar. Both are lever trims on their own device platforms, so verify the device before ordering.
17) Can I use a passage function exit trim in place of the 210K?
Only if the opening does not need to be secured from the outside. The 210K is keyed - the key locks and unlocks the knob and a cylinder is furnished. Passage trims have no key control at all: the Arrow SRX01 Sierra lever with rose for ED910, S1150 and S1250 devices, the Corbin Russwin 3310AET for ED300 Series, the x810ET for ED4000 Series, and the x910ET heavy duty trim for ED5200S, ED5200, ED5400 and ED5800 Series are all passage function. Those free-wheel the door open from the outside whenever the device is installed, which is the opposite of what a keyed knob trim is for.
18) I want to standardize a facility on Grade 1 exit trim - which trims besides the Von Duprin 210K carry a Grade 1 rating?
The 210K is Grade 1 and heavy duty. Other Grade 1 exit trims across brands include the Sargent 704ET and 704-ETL night latch lever trims, both Grade 1 heavy duty; the Design Hardware KIL entry and storeroom trims and the LE08 entry trim with flat lever and escutcheon; the Dexter ED1000T classroom thumbpiece trim and the ED1500T lever trim; the Command Access ET26 electrified trim; and the Pamex E9000 storeroom lever trim. Grade 1 is a performance rating, not a fit spec - each of these still mounts only to its own exit device series, so a standard written across a building has to name the device family alongside the trim.
19) The opening needs a keypad rather than a key - what replaces the 210K?
The 210K is a mechanically keyed knob trim using a six-pin Schlage "C" keyway. For pushbutton credential entry at the exit device, Dormakaba offers the E-Plex 201U electronic pushbutton exit trim in wide stile and the PowerPlex P201U exit trim for rim, mortise and surface vertical rod devices. Those change how the opening is credentialed, so plan for the programming and the device platform they mount to before swapping away from a keyed trim.
20) Is the Falcon 179L a lighter-duty version of the Von Duprin 210K?
They are not the same class of trim. The 210K is rated heavy duty with a 10 gauge (2.4mm) steel escutcheon. The Falcon 179L is a lever control trim for 1790 Series devices, classroom function, rated medium duty. So the differences run three ways: lever versus knob, classroom function versus key locks and unlocks, and medium duty versus heavy duty. The 179L also fits the Falcon 1790 Series platform rather than the Von Duprin 22 Series.
21) Do I need to specify handing when cross-shopping the 210K against other exit trims?
Not for the 210K itself - it is non-handed, so one part covers left and right hand openings. Some comparable trims solve handing a different way by being field reversible, including the Sargent 704ET night latch lever trim and the Command Access ET26 electrified trim, both of which are set at install rather than specified at order. Where a trim is neither non-handed nor reversible, handing has to be confirmed against the door before the order goes in.
22) What finishes does the Von Duprin 210K knob trim come in?
Four finishes: 526 powder coated chrome, 622 matte black, 689 powder coated aluminum, and 695/SP313 dark bronze. If you're matching existing openings, 689 aluminum and 695 dark bronze are the two that typically pair with painted aluminum and bronze storefront, while 622 matte black is the choice on newer dark-hardware packages.
