    Von Duprin 98EO 3 US26D – Frequently Asked Questions

    1) Will the Von Duprin 98-3FT fit my door? It's a 36 inch hollow metal leaf.
    The 98-3FT is sized for a 36 inch door and covers a door thickness range of 1-3/4 to 2-1/4 inches, so it handles the standard 1-3/4 inch commercial leaf as well as the thicker 2-1/4 inch doors found on some institutional openings. Fasteners for 1-3/4 and 2-1/4 inch doors come with the device. One number worth checking before you commit: the device projects 3-13/16 inches off the door face, so confirm that clears anything on the wall the door swings against and still leaves the corridor width you need.
    2) Do I have to order the Von Duprin 98 rim exit device left hand or right hand?
    The 98-3FT is non-handed as standard, so the same device goes on a left hand reverse or a right hand reverse opening without any field reversal. Handing only becomes a factor when you apply the SD, -2 or SS options, which are handed. Outside trim is a separate order line, and a lever trim does have to suit the swing.
    3) Can I use the Von Duprin 98 rim exit device on a pair of doors with no center post?
    A rim device latches into a strike mounted on the frame stop, so a pair with no center post needs a mullion: hang a 98 device on each leaf and both latch into the mullion. The Von Duprin 4954 removable steel mullion, or the KR4854-S keyed removable mullion prepped for the 299 strike, lifts out when you need the full clear opening for moving equipment or furniture. If the opening cannot take a mullion at all, order the device with the 27 suffix instead. That makes it a surface vertical rod device latching at the head and the threshold, which secures the pair with nothing between the leaves.
    4) Is the Von Duprin 98-3FT fire rated? I need panic hardware for a labeled door.
    No. The 98-3FT is not a fire rated device. UL 10C and CAN/ULC-S104 apply only to the fire rated configurations of the 98 Series, and this one ships with hex key dogging, which a labeled opening cannot have because the latch must stay live at all times. For a fire door, order a rim device that carries the rating: the Dexter ED1000 Series Grade 1 fire rated rim device, the Marks USA M9900F in 36 inch, or the Orca Hardware OED85 in 36 inch are all fire rated rim devices.
    5) Will a Von Duprin 98-3FT mount on a narrow stile aluminum storefront door?
    No. This is a wide stile device, and its center case alone measures 8 x 2-3/4 x 2-3/8 inches, which a narrow storefront stile will not carry. For aluminum storefront, use a device built for narrow stile: the Adams Rite 8800 Series covers 1-3/4 to 2-1/4 inch doors like the 98 does, the Corbin Russwin ED4200 is a Grade 1 narrow stile rim device, and the Adams Rite 3700 Series is the narrow stile option when the opening is fire rated.
    6) How do you get in from the outside on a Von Duprin 98 rim exit device?
    The device on its own is exit only, so entry from outside comes from the trim you specify with it. Night latch (NL) with a 990 pull is the common pick when a key should retract the latch; 996 lever or knob trim is available in classroom, storeroom, passage and dummy functions when you want a handle on the outside face. Thumbpiece (TP), blank escutcheon versions of the lever, knob and thumbpiece, key capture lever, and night latch with optional pull are all listed as well. Order EO if the outside face never needs to open.
    7) The 98-3FT is too wide for my aluminum storefront stile. What rim exit device fits a narrow stile door instead?
    The Von Duprin 98-3FT is a wide stile device with a center case measuring 8 inch x 2-3/4 inch x 2-3/8 inch, which needs more stile face than a typical storefront rail gives you. For narrow stile openings, the Adams Rite 8800 is a Grade 1 narrow stile rim device covering 1-3/4 inch to 2-1/4 inch door thickness, the Corbin Russwin ED4200 is a Grade 1 narrow stile rim device at 36 inches that accepts trim, and the Falcon 19-R is a Grade 1 narrow stile exit only device at 36 inches for 1-3/4 inch doors. The Adams Rite EX88 is another Grade 1 narrow stile interlocking rim device.
    8) I am putting panic hardware on a wood door. Is the Von Duprin 98-3FT the right device, or should I use something else?
    The Von Duprin 98-3FT is specified for metal doors rather than wood, and its fasteners are supplied for wood or metal doors 1-3/4 inch and 2-1/4 inch thick on the door prep side. When the door itself is wood, the Adams Rite 8700 is a Grade 1 narrow stile rim device listed as wood door compatible, and the Adams Rite 3700 is a Grade 1 fire rated narrow stile rim device also listed as wood door compatible. Both are narrow stile devices at 30 inches, so confirm the leaf width and stile face before ordering.
    9) My opening is a fire-rated door assembly. Which 36-inch rim exit device is listed fire rated?
    The Von Duprin 98-3FT as configured is a non-fire-rated rim device. For a labeled opening, the Marks USA M9900F is a fire rated exit only rim device at 36 inches, the Orca Hardware OED85 is a fire rated exit only rim device at 36 inches, and the Dexter ED1000-R-F-EO is a Grade 1 fire rated rim exit device. Fire rated devices do not dog, so plan on the door latching on every cycle rather than being held retracted for daytime traffic.
    10) What rim exit device covers a 48-inch door if the 98-3FT is built for a 36-inch leaf?
    The Von Duprin 98-3FT is sized for a 36-inch door. For a 48-inch leaf, the DORMA 9300 is a Grade 1 heavy duty wide stile rim device at 48 inches covering 1-3/4 inch to 2-1/4 inch door thickness, which matches the same thickness range. The Sargent 2828 is a Grade 1 reversible wide stile exit only rim device for a 48-inch minimum door width, and the Marks USA M9900F is offered as a fire rated exit only device at 48 inches for labeled openings.
    11) I need outside lever or key access on the exit door. Which comparable rim devices take outside trim and which are exit only?
    The Von Duprin 98-3FT is built around a trim function selection that includes lever, knob, thumbpiece, night latch, night latch with optional pull, key capture, blank escutcheon, dummy trim, and exit only. Among comparable devices, the Corbin Russwin ED5200 wide stile and Corbin Russwin ED4200 narrow stile are both listed as exit only or accepting trim, and the Detex V4003A/03AN is a Grade 1 wide stile device offered with night latch trim. Devices such as the Corbin Russwin ED2200, the Orca Hardware OED55, the Imperial USA ED-501, and the Marks USA M9900 are listed exit only, so outside access has to come from a separate cylinder or reader.
    12) Can an SDC MSB550 or PSB560 exit bar be used in place of a Von Duprin 98-3FT?
    They solve different problems. The Von Duprin 98-3FT is a mechanical latching rim device with a 3/4 inch latch throw that secures the door on its own. The SDC MSB550 is a 36-inch mechanical switch bar that releases an electromagnetic lock, and the SDC SureExit PSB560 is a 36-inch pressure sense bar with tri-failsafe technology, both fitting narrow or wide stile doors; the Securitron EMB is an electromechanical exit bar listed for 2-1/4 inch doors. Those bars signal a separate locking device, so the opening still needs the maglock or electric lock they release.
    13) What strike does the Von Duprin 98 rim device latch into, and can I reuse the strike on my frame?
    Rim device, so the latch throws 3/4 inch into a surface strike on the frame stop, not into a mortise strike pocket in the jamb. The Von Duprin 299 rim strike is what the device is set up for and it ships with the device, so plan on mounting the 299 rather than reusing a strike left from a cylindrical or mortise lock. On a pair, the mullion is prepped for the same 299 strike.
    14) My hollow metal doors are prepped with an 86 cutout. Will the Von Duprin 98 cover it?
    The 98 Series smooth case is made to go onto hollow metal doors prepped with 86 or 161 cutouts, so an existing prep of either type is what this device expects. The center case measures 8 x 2-3/4 x 2-3/8 inches and the assembled device stands 3-13/16 inches off the door face. If your leaf carries an odd prep from a discontinued device, measure it against those case dimensions before ordering.
    15) Can the Von Duprin 98-3FT be held unlocked during business hours?
    Hex key dogging is standard on the 98-3FT: an Allen wrench holds the pad and latchbolt retracted so the door runs push/pull through the day, and you undog it at close. If handing a loose hex key to staff is a problem, the device can be ordered with cylinder dogging so it takes a key instead, and the CDSI and HDSI options add a security indicator that shows at a glance whether the device is dogged or live. Dogging is on the table here only because this device is not fire rated.
    16) How do I tie a Von Duprin 98 exit device into a card reader or access control system?
    Two routes, and they solve different problems. QEL quiet electric latch retraction sits inside the device and pulls the latch back on a valid credential, leaving the door push/pull until the system relocks it, which is what you want when the access system has to control the pad itself. Or keep the device mechanical and electrify the frame instead with the Von Duprin 954 electric strike, which is built for rim exit devices. QEL and the other electrified options are field configurable kits on the 98 Series, so a device already hanging on the door can be converted rather than replaced.
    17) Can a Von Duprin 98 Series exit device do delayed egress on a stairwell or a memory care door?
    Yes, with the CX delayed egress option, Von Duprin's CHEXIT. Push the pad and the device holds the door for 15 seconds before releasing, and it is built to the NFPA and IBC delayed egress requirements. It is one of the field configurable options on the 98 Series rather than a separate device, so it can be specified up front or added later.
    18) I need low operating force panic hardware for an accessible entrance. Does the Von Duprin 98 have an option for that?
    Order it with the AX accessible device upgrade, which is certified to a 5 lb operating force for ADA. It is a device option on the 98 Series, not a different model, so the rest of the specification, 36 inch device, 1-3/4 to 2-1/4 inch door, trim and finish, stays the same.
    19) What is the difference between the Von Duprin 98 and the 99, and can I match the finish on the rest of my doors?
    It comes down to the look of the mechanism case. The 98 has a smooth case, the 99 has a grooved one, and they are otherwise the same family, specified together as the 98 & 99 Series. Match whichever is already on the building so the openings read the same. Finish is not a limitation either way: the 98-3FT is offered in 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome, 626 satin chrome, 628 aluminum, 630 satin stainless, 643E aged bronze, 710 dark bronze anodized and 711 flat black.
    20) Is the Von Duprin 98-3FT heavy enough for a school or hospital entrance that gets used all day?
    It is a Grade 1 device certified to ANSI/BHMA A156.3 2014 and ANSI/UL 305, with a wide stile push pad built for high abuse traffic, which is the tier institutional buyers standardize on. Standardizing is easier here than most: one device number covers 1-3/4 through 2-1/4 inch doors, and the suffix system takes the same 98 platform out to surface vertical rod (27), concealed vertical rod (47 and 48), 3-point latching (57) and mortise (75), so a whole building can run one series across different opening types. If a given opening is genuinely light duty, a Grade 2 rim device such as the Cal-Royal 5000 in 36 inch is the lighter alternative.
    21) My doors are 2-1/4 inch thick. Which rim exit devices cover that thickness?
    The Von Duprin 98-3FT covers a door thickness range of 1-3/4 inch to 2-1/4 inch and ships with fasteners for wood or metal doors 1-3/4 inch and 2-1/4 inch thick. Among comparable devices, the Adams Rite 8800 lists the same 1-3/4 inch to 2-1/4 inch range in a narrow stile, and the DORMA 9300 lists it in a 48-inch wide stile device. Several other rim devices, including the Corbin Russwin ED5200, the Falcon 19-R, and the Arrow ED910, are listed at 1-3/4 inch door thickness, so check the thickness before swapping one in on a heavy leaf.
    22) Is there a lighter duty push bar rim device than the Grade 1 Von Duprin 98-3FT for a low traffic service door?
    The Von Duprin 98-3FT is certified Grade 1 for high-use institutional openings. If the opening does not call for Grade 1, the Cal-Royal 5000 is a heavy duty 36-inch touch bar rim device with a Grade 2 chassis, and the Cal-Royal 5500 is a Grade 2 heavy duty push bar rim device at 48 inches. The Design Hardware 2000R is a standard duty wide stile rim device at 33 inches with hex key dogging, while the Design Hardware 1000R is the heavy duty device in the same 33-inch size, also with hex key dogging.
    23) Is a concealed vertical rod device like the Hager 4501 a drop-in replacement for the Von Duprin 98-3FT?
    No. The Von Duprin 98-3FT is a rim device that latches into a strike on the frame, so the door prep and the strike location are different from a vertical rod device. The Hager 4501 is a Grade 1 concealed vertical rod device at 36 inches with a wide stile pushpad, latching top and bottom instead, and the Hager 4601 is the narrow stile concealed vertical rod version at 36 inches. If you want a Hager rim device on the same opening, the Hager 4701 is a standard duty rim device at 36 inches with Grade 1 BHMA certification.
    24) The existing panic hardware in my building uses a crossbar, not a push pad. What comparable device keeps the crossbar look?
    The Von Duprin 98-3FT uses a push pad style actuator, so it will not visually match a crossbar device. The CRL Jackson 1095 is a wide stile exit only crossbar rim panic device at 48 inches, and the Corbin Russwin ED3200 is a Grade 1 wide stile crossbar rim device at 48 inches listing a 1-3/4 inch door thickness. The CRL Jackson 1095P is the paddle actuator version of the same series for a different touch style.
    25) I am tying the exit door into access control. How do the electrified rim devices compare with the Von Duprin 98-3FT?
    The Von Duprin 98-3FT is offered with electric latch retraction options including EL, QEL, and pneumatic retraction, along with RX, LX, and combination monitoring switches, on a device that covers 1-3/4 inch to 2-1/4 inch door thickness. The SDC S6136 Spectra is an electrified architectural rim device at 36 inches on a 4 inch wide stile, listed for 1-3/4 inch to 2 inch door thickness. The Dormakaba E2103 is an electrified 36-inch rim device supplied with 4908A trim in a classroom function, which fixes the outside function at the device rather than leaving it to a trim selection.
    26) Which comparable rim exit devices come with hex key dogging like the Von Duprin 98-3FT?
    Hex key dogging is the standard dogging configuration on the Von Duprin 98-3FT, which lets the latchbolt be held retracted for push and pull traffic during open hours. Among comparable devices, the Design Hardware 1000R is a 33-inch heavy duty rim device with hex key dogging and the Design Hardware 2000R is the 33-inch standard duty version with hex key dogging. The Stanley Security QED211 is a Grade 1 heavy duty narrow stile rim device with hex-key dogging for storefront style openings.
    27) What goes on the inactive leaf where the hardware needs to match but must not latch?
    The Von Duprin 98-3FT is a latching rim device with a 3/4 inch latch throw, though its trim function selection does include dummy trim. Where the whole device needs to be non-functioning, the Detex Advantex 00 Series is a Grade 1 wide stile dummy exit device, and the Sargent 12-8810 is a Grade 1 fire rated wide stile device listed in a dummy function with RX and motor electric latch retraction. Matching the pushbar height and projection across the pair of leaves is what keeps the opening looking consistent.
