Von Duprin 98EO-F 4 US26D – Frequently Asked Questions

1) Can I put a Von Duprin 98F exit device on a wood door?
No. The 98F-4FT is not rated for wood door application, so on a wood door you need a different device. If the opening is wood and fire rated, the Adams Rite 3700 Series narrow stile rim device is wood door compatible and fire rated; the Adams Rite 8700 Series is the wood door compatible option where no fire rating is required. Note the 98F does ship with fasteners sized for wood or metal doors 1-3/4 inch and 2-1/4 inch thick, but the fastener pack is not the same thing as an approved wood door application.
2) Does the Von Duprin 98F-4FT carry a fire rating for a labeled opening?
Yes, the 98F is fire rated and listed to ANSI/UL 10C and CAN/ULC-S104, and it is certified to ANSI/BHMA A156.3 2014 Grade 1 plus ANSI/UL 305 and CAN/ULC-S132 for panic hardware. That combination is what a fire labeled cross corridor or stair door in a school or hospital needs. One consequence of the fire listing: a fire rated device is supplied less dogging, so the latch cannot be held retracted to leave the door push-pull during the day.
3) Do I have to specify handing on a Von Duprin 98 rim exit device?
The 98 rim device is non-handed as a mechanism, so it works on either hand of door out of the box. Handing is still an order selection (RHR or LHR) because trim and certain options key off it, and it stops being non-handed once you add SD, the -2 double cylinder, or the SS signal switch. If you are specifying any of those, get the hand right on the order.
4) Will a rim exit device work on my pair of doors, or do I need vertical rods?
A rim device latches into a strike on the frame or on a mullion, so on a pair it needs a removable mullion between the leaves. If you cannot have a mullion, the 98/99 Series is built in other device types on the same push pad: surface vertical rod (27), concealed vertical rod with a 5/8 inch bottom bolt (47) or 1-1/2 inch bottom bolt (48), concealed vertical cable (49), one point concealed cable (52), three point latching (57), and mortise (75). Vertical rod versions latch at the head and sill so the pair works with a clear opening between the leaves.
5) My aluminum storefront door has a narrow stile. Can I use a wide stile rim device on it?
No. The 98F is a wide stile device and the push pad and case need the door face width a wide stile door gives you; an aluminum storefront stile will not take it. For narrow stile openings look at the Adams Rite 8800 Series, which is a Grade 1 narrow stile rim device for 1-3/4 to 2-1/4 inch doors, the Corbin Russwin ED4200, or the Falcon 19-R for 1-3/4 inch doors. If that narrow stile opening is also fire rated, the Adams Rite 3700 Series is the narrow stile device with a fire rating.
6) Can I dog the Von Duprin 98F open during business hours?
Not mechanically. The 98F-4FT is supplied less dogging because it is a fire rated device, and mechanical dogging is not permitted on a fire door. If you need the door to be push-pull during the day on a labeled opening, the electric latch retraction route (EL or QEL) is how it is done, since it releases on fire alarm. On a non rated opening you have more choices; the Design Hardware 1000R and 2000R rim devices, for example, use hex key dogging.
7) What is the closest fire rated 48 inch rim exit device to the Von Duprin 98F-4FT?
The Marks USA M9900F-48 is a 48 inch fire rated rim panic exit device, exit only with a panic protector end cap. Compared to the 98F-4FT, which is a fire rated wide stile rim device with a 48 inch product size, Grade 1 certification and a 3/4 inch latch throw, the Marks device covers the same door width and fire rated requirement in an exit only configuration, so trim function is the point to confirm before swapping.
8) Is the Cal-Royal 5500 a substitute for the Von Duprin 98F-4FT?
They are not interchangeable on a fire rated opening. The Cal-Royal 5500 is a 48 inch wide rim exit device with a push bar, heavy duty, carrying a Grade 2 rating and no fire rating. The 98F-4FT is Grade 1 and fire rated. On a non-rated 48 inch opening the Cal-Royal covers the same door width; where the drawing calls for a fire rated Grade 1 device, it does not.
9) Which 48 inch wide stile rim exit devices are alternatives to the Von Duprin 98F?
For 4 foot leaves, the Dormakaba 9300 Series is a 48 inch wide stile panic rim device, exit only, Grade 1 heavy duty, covering 1-3/4 inch to 2-1/4 inch door thickness. The Corbin Russwin ED3200 is a Grade 1 48 inch wide stile crossbar rim device for 1-3/4 inch doors, and the Sargent 2828 is a Grade 1 reversible wide stile rim device for a 48 inch minimum door width. The 98F-4FT is a wide stile push pad device with a 48 inch product size, so the Dormakaba 9300 and Sargent 2828 keep the push pad or bar format while the ED3200 changes the actuator to a crossbar.
10) Is an SDC pressure sense bar or switch bar the same thing as a Von Duprin 98F rim exit device?
No. The SDC SureExit PSB560 is a 36 inch pressure sense bar with tri-failsafe technology and the SDC MSB550 is a mechanical switch bar that releases an electromagnetic lock; both are non-rated and fit narrow or wide stile. They actuate a separate locking device rather than latching the door themselves. The 98F-4FT is a fire rated rim exit device with its own 3/4 inch latch throw, so a rated opening that needs mechanical latching is not served by a switch or sense bar.
11) What is a fire rated rim exit device option if the opening is 36 inches rather than 4 feet?
The Von Duprin 98F-4FT is built to a 48 inch product size. On a 36 inch leaf, the Marks USA M9900F-36 is a fire rated exit only rim device with a panic protector end cap, the Orca Hardware OED85 Series is a 36 inch fire rated rim exit device, and the Arrow FS1250 is a fire rated 32 inch rim exit device for 1-3/4 inch doors.
12) For a high abuse opening in a school, what compares to the Von Duprin 98F on duty level?
The 98F-4FT is a Grade 1 commercial device built for high use institutional openings. Among peers, the Detex 10 Advantex Series 36 inch is Grade 1 wide stile rated extra heavy duty, and the Detex 40 Advantex is Grade 1 extra heavy duty in a narrow stile build. The Dormakaba 9300 Series is Grade 1 heavy duty wide stile. Note that the Detex 10 and Dormakaba 9300 are not fire rated, so a rated opening keeps you on the 98F.
13) Will the 98F latch into the strike I already have on the frame?
The 98F throws a 3/4 inch latchbolt into a surface mounted rim strike on the frame stop. If the door currently has a rim device from another maker, plan on the new strike that comes with the Von Duprin rather than reusing the old one, since strike position is set to the device. Where the frame prep is the constraint, the 3/4 inch throw and the 3-13/16 inch projection are the two numbers to check against the existing stop and clearance.
14) What outside trim options can I order with the Von Duprin 98F?
Trim runs from no outside operation to full keyed entry: exit only, dummy trim, night latch and night latch with optional pull, knob and lever in plain, blank escutcheon, night latch and key capture versions, and thumbpiece with or without blank escutcheon. Pick lever style separately (01, 02, 03, 05, 06, 07, 17 or 18) when you order an L trim. For a classroom or office where staff enter with a key and the door always exits free, night latch trim is the usual choice; exit only where nobody comes back in that way.
15) Can the 98F exit device tie into my access control system?
Yes. Electric latch retraction is available as EL, QEL for quiet operation, or PN pneumatic, which lets the card reader or a scheduled unlock pull the latch back and leave the door push-pull. For monitoring, order an RX request to exit switch, an LX latchbolt monitor, or the LX-RX combination, plus low current, double RX, waterproof RX and signal switch versions. Alarm kits (ALK, RX-ALK, LXRX-ALK) cover local alarm on the door. CDSI and HDSI dogging indicators and the CX CHEXIT 15 second delayed egress option are also field configurable.
16) What is the AX option on a Von Duprin 98 and do I need it for ADA?
AX is the accessible upgrade that brings operating force down to the 5 lb requirement in the 2010 ADA standards (chapters 404.2.7 and 30934) and the 2013 California Building Code chapter 11B-309.4. If your project is being reviewed against those, order the device with AX rather than trying to adjust a standard device into compliance. QM, quiet mechanical, is a separate option and is about noise, not force, which matters on hospital and dorm corridors.
17) What is the difference between the Von Duprin 98F-4FT and the Corbin Russwin ED5200?
Both are Grade 1 wide stile rim exit devices. The Corbin Russwin ED5200 is a 36 inch device for 1-3/4 inch doors, exit only or accepting trim, and is not fire rated. The Von Duprin 98F-4FT is fire rated, has a 48 inch product size, a 3/4 inch latch throw and a 1-3/4 inch door thickness. For a 36 inch non-rated opening the ED5200 is the direct wide stile counterpart; for a rated 4 foot leaf it is not.
18) I only need exit only hardware on a non-rated door. What is a simpler alternative to the Von Duprin 98F?
The 98F-4FT is fire rated and supports trim functions from exit only through lever, knob, thumbpiece and night latch. If the opening is not rated and needs nothing but egress, the Dexter ED1000-R-EO-4FT is a Grade 1 4 foot rim exit device, and the TownSteel ED1100 is a 36 inch Grade 1 heavy duty wide stile panic rim device. Both are exit only builds without the trim range.
19) Which exit devices standardize with the Von Duprin 98F if some doors in the building are paired and need vertical rod hardware?
The 98 Series covers rim, surface vertical rod, concealed vertical rod, concealed vertical cable and mortise configurations, so a facility can stay within one series across opening types. Across brands, the Hager 4501 Series is a Grade 1 36 inch concealed vertical rod exit device with a wide stile pushpad and the Hager 4601 is the narrow stile concealed vertical rod version, both non-rated, while the Hager 4701 is the Grade 1 rim device in the same family.
20) What is the difference between a push pad exit device like the Von Duprin 98F and a crossbar device?
The 98F-4FT uses a push pad actuator on a wide stile chassis. Crossbar devices such as the CRL Jackson 1095 Series 48 inch crossbar rim panic device and the Corbin Russwin ED3200 Grade 1 48 inch crossbar rim device use a horizontal bar across the door face instead; both are non-rated wide stile devices. The choice changes the face appearance and the actuation surface, and on a rated opening the crossbar options above do not carry a fire rating.
21) Is the Sargent 12-8810-LTRIM an equivalent to the Von Duprin 98F with lever trim?
The Sargent 12-8810-LTRIM is a fire rated Grade 1 wide stile rim exit device with RX and motorized electric latch retraction, and its listed function is dummy. The Von Duprin 98F offers live lever trim functions including L, L-BE, L-KC and L-NL along with RX request to exit switching and QEL quiet electric latch retraction. Confirm whether the opening needs a dummy trim or a working lever before treating the two as equivalent.
22) What is a night latch alternative to the Von Duprin 98F NL trim?
The 98F offers NL night latch, NL-OP night latch with optional pull, K-NL and L-NL trim functions on a wide stile chassis. The Sargent 8504 is a Grade 1 narrow design rim exit device in a night latch function, and the Detex V4003A/03AN is a Grade 1 wide stile rim exit device with night latch trim. The Detex keeps the wide stile format; the Sargent 8504 is narrow stile.
23) Which rim exit devices besides the Von Duprin 98F are non-handed?
The Von Duprin 98F rim device is non-handed. The BEST Precision 5101 Series is a rim exit device with a non-handed universal design, the BEST 2401 Series is a non-handed narrow stile exit only rim device, and the CRL Jackson 1295 Series is a non-handed push pad rim panic device for 1-3/4 inch doors, exit only and non-rated. On a rated opening, the 98F is the one of these carrying a fire rating.
24) What finishes does the Von Duprin 98 exit device come in for matching existing hardware?
Twelve finishes: 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 steel, 643E aged bronze, 710 dark bronze anodized and 711 flat black. On a building where you are replacing devices a few at a time, 626 satin chrome and 630 satin stainless are the ones that most often match existing institutional hardware, and 628 aluminum matches storefront framing.
25) Can I get a Braille or glow in the dark push bar on a Von Duprin 98?
Yes. Besides the standard bar, the push bar is available as BR Braille, KN knurled, SG safety glow, and RSS emergency exit push bar. Knurled bar is the traditional tactile warning on a door that should not be used for normal traffic, and safety glow helps in a stair or corridor when the lights drop.
