Von Duprin XP98/XP99-4 48" Wide Stile Rim Exit Device with Patented Smart Latch

Heavy-Duty Institutional Rim Exit Device with Patented 2-Piece Latchbolt Security

The Von Duprin XP98/XP99-4 is a 48" wide stile rim exit device engineered for single and double doors requiring increased security in high-demand institutional environments. Featuring Von Duprin's patented XP 2-piece latchbolt design, the “smart” latch changes shape when subjected to external forces, enabling the exit door to withstand external attack and remain secure. The patented latch bolt design provides greater, longer-lasting latch bolt to strike contact that is not easily affected by the twisting motion of a weakened frame. Certified to ANSI/BHMA A156.3 2014 Grade 1 and UL listed for panic exit hardware, this device is built for schools, hospitals, and government buildings where dependable performance is essential. The device accommodates door thickness of 1-3/4" and features a 3/4" latch throw, with a center case measuring 8" x 2-3/4" x 2-3/8" and a product projection of 3-13/16".

Professional Features & Benefits

  • Hex Key Dogging Configuration: Standard hex key dogging allows authorized personnel to hold the latch in the retracted position for high-traffic periods, with non-handed operation for simplified installation.
  • Industry Certifications: Certified to ANSI/BHMA A156.3 2014 Grade 1, UL listed (ANSI/UL 10C for fire-rated configurations, ANSI/UL 305), CAN/ULC-S104 (fire-rated only), and CAN/ULC-S132 for comprehensive code compliance.

Von Duprin VON-XP98-4-626 – Frequently Asked Questions

1) What door thickness does the Von Duprin XP98/XP99-4 exit device work on?
Doors 1-3/4 inches thick. That's the standard commercial door thickness, so it covers most hollow metal openings. The fasteners in the box cover wood or metal doors at 1-3/4 and 2-1/4 inches, but the device itself is specified for 1-3/4 inch doors. If you're working a 2-1/4 inch thick opening, the Dormakaba 9300 Series 48 inch wide stile rim device carries a 1-3/4 to 2-1/4 inch thickness range.
2) Do I have to order the Von Duprin XP98/XP99 exit device handed?
No handing to specify on the device. The XP98/XP99-4 is non-handed, and the function is field selectable between exit only, dummy trim and night latch. Handing does come back in on the trim: night latch, lever, and lever variants are ordered left hand reverse or right hand reverse, so you need the swing before you pick the 990NL or 996L trim.
3) How do I get a lever or knob function on a Von Duprin 98/99 exit device?
Pick the outside trim as a separate line. On the XP98/XP99, exit only, dummy trim and night latch are selectable in the field, but for thumbpiece, knob or lever you remove the NL drive screw from the device first. Trim options run 990DT dummy, 990NL night latch, 990TP thumbpiece, 996K knob and 996L lever, each also offered with a blank escutcheon or combined with dummy or night latch. Lever trims default to the 06 lever, with 03, 07, 17 and Latitude available.
4) Will the Von Duprin XP98/XP99 latch into my existing rim strike?
The XP98/XP99-4 throws its latchbolt 3/4 inch and projects 3-13/16 inches off the door face. The XP latch is a patented 2-piece design that changes shape under attack, so it keeps latchbolt to strike contact even when a frame has been twisted or weakened. If your current strike was set for a standard rim device with a 3/4 inch throw, the geometry matches; what you need to confirm on site is the strike position against the 3-13/16 inch projection at the frame.
5) Can you dog down a Von Duprin XP98/XP99 exit device during business hours?
Yes, hex key dogging is standard on the XP98/XP99-4, which holds the latch retracted so the door pushes free during high traffic. If you want a key to do it instead, order CD cylinder dogging, or CDSI/HDSI to add a security indicator that shows whether the device is dogged. Other choices are SD special center case dogging, DI or CI dogging indicators, and LD less dogging when the opening is fire rated and dogging isn't permitted.
6) What grade is the Von Duprin XP98/XP99 rim exit device certified to?
Grade 1, certified to ANSI/BHMA A156.3 2014, and UL listed for panic exit hardware under ANSI/UL 305, with ANSI/UL 10C for fire rated configurations plus CAN/ULC-S104 (fire rated only) and CAN/ULC-S132. Grade 1 is the highest ANSI/BHMA durability tier, which is why this is the spec that goes on school, hospital and government openings. Many competing devices in the same size are Grade 2, including the Cal-Royal 5500 48 inch push bar device.
7) My opening is a fire rated 48 inch door. What rim exit device should I use instead of the XP98/XP99-4?
For a 48 inch fire rated opening, the Marks USA M9900F 48 inch rim panic exit device is the direct size match: it is fire rated, exit only, and comes with the Panic Protector end cap. If the leaf is narrower, the Marks USA M9900F 36 inch version, the Orca Hardware OED85 36 inch fire rated rim device, and the Dexter ED1000 Series fire rated Grade 1 rim device cover the same requirement at smaller widths. Order the fire rated device by its fire rated part number rather than adding a fire label to a non-rated device.
8) The XP98/XP99-4 will not fit my aluminum storefront door. What rim exit device fits a narrow stile instead?
The XP98/XP99-4 is a wide stile device, so a narrow aluminum stile calls for a narrow stile rim device instead. Adams Rite narrow stile options include the 8800 Series 30 inch, which is Grade 1 and covers doors 1-3/4 inch to 2-1/4 inch thick, the 8700 Series 30 inch, and the fire rated 3700 Series 30 inch, all with starwheel interlocking. Corbin Russwin ED4200 is a Grade 1 narrow stile rim device at 36 inch for 1-3/4 inch doors, and Falcon 19-R is a Grade 1 narrow stile exit only rim device at 36 inch for 1-3/4 inch doors. Detex 40 Advantex is a Grade 1 extra heavy duty narrow stile rim device where the storefront sees institutional traffic.
9) Is a Cal-Royal 5500 48 inch exit device the same thing as the Von Duprin XP98/XP99-4?
They cover the same 48 inch opening but sit at different certification levels. The XP98/XP99-4 is ANSI/BHMA Grade 1 with the patented XP two-piece latchbolt that changes shape under external force. The Cal-Royal 5500 is a 48 inch wide rim exit device with a push bar rated Grade 2 heavy duty. The Cal-Royal A9820 is likewise a 48 inch rim device listed Grade 2. If a project specification calls for Grade 1 exit hardware, the Cal-Royal 48 inch devices will not satisfy it.
10) The XP98/XP99-4 is a rim device and my pair of doors has no mullion. What exit device type do I use instead?
A rim device such as the XP98/XP99-4 latches to a strike on a mullion or the frame stop. On a pair with no mullion, a vertical rod device latches top and bottom into the head and threshold instead: the Hager 4501 Series 36 inch is a Grade 1 concealed vertical rod device with a wide stile pushpad, and the Hager 4601 Series 36 inch is the Grade 1 concealed vertical rod device in narrow stile. The Dormakaba QED200 is a Grade 1 heavy duty narrow device supplied with a 7 foot rod.
11) Should I use a rim exit device or a vertical rod device on a pair of doors?
A rim device like the XP98/XP99 latches into a strike on the frame or, on a pair, into a mullion between the leaves. If you don't want a mullion in the opening, you need a vertical rod device instead, which latches at the head and the sill. The 98/99 platform covers both: rim, surface vertical rod (27), concealed vertical rod (47, 48), concealed vertical cable (49, 52), 3-point latching (57) and mortise (75). Same push pad, different latching, so you can standardize the look across single and paired openings.
12) What is the difference between the Von Duprin 98 and 99 exit device?
Case appearance, nothing else on this device. The 98 is the smooth case and the 99 is the grooved case, and both come in the same 12 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, 643E aged bronze, 710 dark bronze anodized and 711 flat black. Property managers matching a run of existing openings usually pick whichever case is already in the building.
13) What electric options can I order on a Von Duprin 98/99 exit device for an access control job?
On the XP98/XP99 you can add RX request to exit or RX-2 double request to exit, LX-LC latch bolt monitoring at low current, E electric locking and unlocking trim, EL electric latch retraction, QEL quiet electric latch retraction, ALK alarm exit kit, and WP-RX waterproof request to exit for an exterior opening. CX CHEXIT delayed egress is also available and meets NFPA and IBC delayed egress requirements. Specify the electric option with the device; these are not field add-ons.
14) Is there an ADA compliant version of the Von Duprin 98/99 exit device?
Yes. Order the AX accessible device option, which is certified to the 5 lb. force ADA requirement. On a standard XP98/XP99 the push pad operating force is not ADA rated, so on an opening that has to meet accessibility requirements the AX suffix is the one to specify at order time.
15) I need a fire rated 48 inch rim exit device, is the Von Duprin XP98/XP99 the right one?
The XP98/XP99 platform is UL listed under ANSI/UL 10C for fire rated configurations and CAN/ULC-S104 fire rated only, but a fire rated exit device must be ordered without mechanical dogging, so you would specify the LD less dogging option rather than the standard hex key dogging. If you want a device that is fire rated out of the box at 48 inches, the Marks USA M9900F 48 inch rim device is fire rated, exit only.
16) I need a crossbar instead of a push pad on a 48 inch door. What replaces the XP98/XP99-4?
The XP98/XP99-4 uses push pad actuation. For a crossbar look on the same 48 inch opening, the Corbin Russwin ED3200 is a Grade 1 48 inch crossbar rim exit device for 1-3/4 inch doors, and the CRL Jackson 1095 Series 48 inch crossbar rim panic device is a wide stile exit only crossbar. CRL Jackson also builds the 1095P in a paddle version and the 1295 Series as a non-handed push pad wide stile device for 1-3/4 inch doors if the crossbar is not required after all.
17) I want electric latch retraction. Is the QEL option on the XP98/XP99-4 the same as buying an electrified device from another maker?
The XP98/XP99-4 takes electrification as ordering options on the device itself, including QEL quiet electric latch retraction, EL electric latch retraction, RX request to exit and LX latch bolt monitoring. Peers that come electrified as their own catalog item include the Sargent 12-8810-LTRIM, a fire rated wide stile Grade 1 rim device supplied with RX and MELR, the Dormakaba E2103 36 inch electrified rim device furnished with 4908A classroom function trim, and the SDC S6136 Spectra 36 inch electrified architectural rim device with a 4 inch wide stile for doors 1-3/4 inch to 2 inch thick. The difference is where the electrification is specified, so match the function and the trim, not just the word electrified.
18) Which other rim exit devices come with hex key dogging like the Von Duprin XP98/XP99-4?
Hex key dogging is standard on the XP98/XP99-4. Among peers, the Design Hardware 1000R 33 inch heavy duty rim device and the 2000R 33 inch standard duty rim device both ship with hex key dogging, and the Stanley Security QED200 Series is a Grade 1 heavy duty narrow stile rim device with hex key dogging. Note that the 1000R and 2000R differ from each other by duty level, and the Stanley unit is narrow stile while the Von Duprin is wide stile.
19) I need a night latch function rim device rather than configuring one. What are my options against the XP98/XP99-4?
The XP98/XP99-4 is field selectable to NL night latch and takes 990NL night latch trim as an ordering option. If a factory night latch configuration is preferred, the Sargent 8504 is a Grade 1 narrow design rim exit device supplied in night latch function, and the Detex V4003A/03AN is a Grade 1 wide stile rim exit device with night latch trim. The Sargent unit is narrow stile, so on a wide stile hollow metal door the Detex is the closer form factor.
20) For a school corridor that takes constant abuse, what compares to the XP98/XP99-4 on durability?
The XP98/XP99-4 is Grade 1 with a patented two-piece latchbolt that resists external attack and keeps latch bolt to strike contact when a frame is weakened or twisted. On the durability question the Detex Advantex line is the peer set: the Detex 10 Advantex 36 inch wide stile device is Grade 1 extra heavy duty, and the Detex 40 Advantex is Grade 1 extra heavy duty in narrow stile. The Dormakaba QED200 and the DORMA 9300 are both Grade 1 heavy duty. Choose by stile type and door width first, since all of these are Grade 1.
21) Does an Arrow or Dexter rim device cover the same door thickness as the XP98/XP99-4?
The XP98/XP99-4 is built for 1-3/4 inch doors, with fasteners included for wood or metal doors 1-3/4 inch and 2-1/4 inch thick. Arrow rim devices at the same 1-3/4 inch thickness include the 3880 Series 30 inch wide stile pushpad exit only bar, the ED910 36 inch rim device, and the 4800 Series 36 inch narrow stile. Dexter offers the ED1000 Series as a Grade 1 rim device in both a 3 foot and a 4 foot length, with the 4 foot matching the 48 inch coverage. If the leaf is thicker than 1-3/4 inch, the Adams Rite 8800 Series and the DORMA 9300 both list 1-3/4 inch to 2-1/4 inch.
22) Is a dummy exit device the same as ordering the XP98/XP99-4 in DT function?
Both give a matching pushbar appearance on the inactive leaf. The XP98/XP99-4 is field selectable to DT dummy trim function, so the same device platform covers the inactive leaf. The Detex Advantex 00 Series is instead a dedicated super heavy duty dummy exit device in wide stile carrying a Grade 1 rating, and the Sargent 12-8810-LTRIM is a fire rated Grade 1 wide stile rim device supplied in dummy function. Match the case appearance of the active leaf device when picking, since the pair should read the same across the opening.
