Heavy-Duty Commercial Rim Exit Device for Single and Double Door Applications

The Von Duprin 99-4FT is a 48" wide stile rim exit device featuring a distinctive grooved mechanism case and heavy-duty push pad design engineered for demanding institutional environments. Certified to ANSI/BHMA A156.3 2014 Grade 1 standards and UL listed for panic exit hardware, this device is built for high-use applications including schools, hospitals, and government buildings.

Professional Features & Benefits

  • 48" Wide Stile Coverage: Designed for 4 ft (48") door applications with wide stile push pad construction, providing reliable egress across a broad door width for high-traffic commercial and institutional use.
  • Grooved Mechanism Case: The 99 Series features a distinctive grooved mechanism case design with a center case dimension of 8" x 2-3/4" x 2-3/8", differentiating it architecturally from the smooth-case 98 Series while sharing the same heavy-duty platform.
  • Grade 1 Certified Performance: Certified to ANSI/BHMA A156.3 2014 Grade 1, the highest industry standard for exit devices, ensuring long-term reliability in the most demanding institutional applications.

  • Non-Handed Design: Standard configuration is non-handed for simplified installation and inventory management. Handed configurations are available when SD (special dogging), -2 (Double Cylinder), or SS (signal switch) options are specified.
  • Hex Key Dogging: Equipped with hex key dogging for convenient hold-open functionality, allowing the latchbolt to be retracted and held for high-traffic periods without repeated push-bar activation.
  • 3/4" Latch Throw with Door Compatibility: Features a 3/4" latch throw and a product projection of 3-13/16". Fasteners are included for wood or metal doors 1-3/4" and 2-1/4" thick. Covers stock hollow metal doors with 86 or 161 cutouts on single doors and may cover cutouts on pairs.

    Von Duprin 99EO 4 US26D – Frequently Asked Questions

    1) Can I put a Von Duprin 99 rim device on a wood door?
    No. The 99-4FT is not rated for wood door use, even though the fastener pack covers wood or metal doors at 1-3/4 inch and 2-1/4 inch. Put it on hollow metal. If the opening is a wood leaf and you need a rim panic, the Adams Rite 3700 Series (fire rated, narrow stile) and the Adams Rite 8700 Series (non fire rated, narrow stile) are the rim devices we carry that are listed wood door compatible.
    2) Do I have to specify a hand when I order a Von Duprin 99-4FT?
    The 99-4FT is non-handed in its standard build, so one device covers either swing. Handing only becomes a real order decision when you add SD special center case dogging, the -2 double cylinder, or SS signal switch, which are handed configurations. Even so, RHR and LHR are selections on the order, so pick the hand that matches the opening as you would call it from the secure side.
    3) Will a Von Duprin 99 rim device latch into the strike that's already on my frame?
    The 99-4FT throws its latchbolt 3/4 inch, which is what a Von Duprin rim strike is prepped for. A rim device latches into a surface strike mounted on the frame stop, not into a mortised ANSI strike pocket, so if what you're replacing was a mortise lock or a cylindrical lockset, the old strike prep does you no good and you'll be mounting a rim strike. Replacing another rim panic, measure the existing strike lip and stop clearance against the 3/4 inch throw before you reuse it.
    4) Will the 99-4FT cover the 86 or 161 cutout already in my hollow metal door?
    On single doors, the 99 Series covers stock hollow metal doors prepped with 86 or 161 cutouts, and it may cover those cutouts on pairs. The center case measures 8 x 2-3/4 x 2-3/8 inches, which is what does the covering. On a pair, verify the cutout position against the case before you commit, because the device mounts closer to the lock edge than it does on a single.
    5) Can I use a rim exit device like the Von Duprin 99 on a pair of doors, or do I need vertical rods?
    A rim device latches into the frame at the lock edge, so on a pair it needs something to latch into: a removable mullion between the leaves. Set up that way, the 99-4FT works on pairs and the mullion carries the strike. Without a mullion, a pair needs vertical rod devices instead, surface or concealed, so each leaf latches at the head and sill. If a clear opening with no center post is the requirement, look at a concealed vertical rod device such as the Hager 4501 Series wide stile CVR rather than a rim.
    6) How does hex key dogging work on the Von Duprin 99, and what if I need to dog it with a key instead?
    Hex key dogging is standard here: you push the pad in, turn the hex wrench, and the latch stays retracted so the door pushes free during business hours. Anyone with the wrench can do it, which is fine on an interior corridor and a problem on a door the public reaches. For that, order CD cylinder dogging so it takes a keyed cylinder, or CDSI and HDSI if you want a security indicator showing at a glance whether the device is dogged. LD less dogging is the choice on doors where the device must never be held retracted. Note that fire rated openings do not get dogging at all.
    7) What trim do I need to order with a Von Duprin 99-4FT, and what does exit only mean?
    The device itself handles egress; the trim decides whether anyone gets in from the outside. EO exit only means no outside trim at all, a push-to-exit door with a blank exterior. NL night latch gives key retraction of the latch from outside. K knob and L lever give a full outside operator, and the lever versions come in 01, 02, 03, 05, 06, 07, 17, and 18 designs so it matches the levers on the rest of the building. There are also thumbpiece (TP), dummy trim (DT), blank escutcheon (BE), and key capture (L-KC) variants. Order the trim function with the device rather than after, since it changes what's inside the case.
    8) Is the Von Duprin 99-4FT Grade 1, and what standards does it meet for a school or hospital spec?
    Certified to ANSI/BHMA A156.3 2014 Grade 1, the top grade for exit devices, and UL listed for panic exit hardware. It also meets ANSI/UL 10C in fire rated configurations, ANSI/UL 305, CAN/ULC-S104 in fire rated configurations, and CAN/ULC-S132. That combination is what gets it through a K-12, hospital, or government facility spec review on both sides of the border.
    9) How do I get a Von Duprin 99 exit device to meet the 5 lb ADA operating force requirement?
    Order the AX accessible device option. That build is certified to the 5 lb force requirements of 2010 ADA Chapters 404.2.7 and 30934 and 2013 California Building Code Chapter 11B-309.4. The standard device is not the AX device, so on an accessible route or a California job, AX has to be on the order line, not assumed.
    10) Can I add electric latch retraction or access control to a Von Duprin 99 later, or do I have to buy it that way?
    Either. Order it configured with QEL quiet electric latch retraction, EL electric latch retraction, or PN pneumatic, plus switches: RX request to exit, LX latchbolt monitor, LX-RX combined, WP-RX waterproof, RX-LC low current, RX-2 double RX, or SS signal switch. Already have a mechanical 99 in the door? The 040061 QEL modular conversion kit converts 33A/35A/98/99 Series 3 ft and 4 ft devices to quiet electric latch retraction, the 050251 adds a request to exit switch, and the 050523 is the EL latch retrofit. That retrofit path is the reason these devices stay in openings for decades while the access control system around them gets replaced.
    11) What Grade 1 rim exit device should I use on a narrow stile aluminum storefront door instead of the 99 Series?
    The Von Duprin 99-4FT is a wide stile device with an 8 inch by 2-3/4 inch by 2-3/8 inch center case, which needs more stile face than a typical aluminum storefront door offers. For narrow stile, the Adams Rite 8800 Series in 30 inch is Grade 1 narrow stile and fits 1-3/4 inch to 2-1/4 inch doors, the Corbin Russwin ED4200 is a Grade 1 36 inch narrow stile device for 1-3/4 inch doors that accepts trim, and the Falcon 19-R is a Grade 1 36 inch narrow stile exit-only device for 1-3/4 inch doors. If you want the trim capability the 99 Series gives you, the ED4200 is the one of those three listed as accepting trim.
    12) The 99-4FT is not fire rated as configured with hex key dogging - what fire rated 48 inch rim device can I use instead?
    For a 48 inch fire rated opening, the Marks USA M9900F-48 is a 48 inch fire rated rim panic exit device, exit only, with a panic protector end cap. In 36 inch, the Marks USA M9900F-36 is the same fire rated device on a narrower door, and the Dexter ED1000-R-F-EO is a Grade 1 fire rated rim device. Note that fire rated openings do not permit mechanical dogging, so the hex key dogging that comes standard on the Von Duprin 99-4FT is not usable on a labeled door - the LD less-dogging configuration is the one that belongs there.
    13) Which of these rim exit devices look like substitutes for a Von Duprin 99 but are actually a different device type?
    Several rim devices in the same size class are not drop-in alternatives to a push pad rim device. The Corbin Russwin ED3200 and the CRL Jackson 1095 are crossbar rim devices rather than push pad devices, so the actuation and the look on the door differ from the 99-4FT push pad style. The Hager 4501 and Hager 4601 are Grade 1 concealed vertical rod devices, which latch top and bottom into the frame and floor instead of into a rim strike. The SDC MSB550 is a mechanical switch bar that releases an electromagnetic lock, and the SDC PSB560 is a pressure sense bar - both signal a lock to release rather than carrying a mechanical latch of their own. Ordering any of these against a 99 rim application changes the strike prep and, for the SDC bars, the locking hardware on the opening.
    14) What Grade 1 wide stile rim device fits a door thicker than 1-3/4 inch?
    The Dormakaba 9300 Series in 48 inch is a Grade 1 heavy duty wide stile rim exit device, exit only, covering 1-3/4 inch to 2-1/4 inch door thickness. The Adams Rite 8800 Series in 30 inch is Grade 1 narrow stile over the same 1-3/4 inch to 2-1/4 inch range. The Von Duprin 99-4FT is specified for 1-3/4 inch doors, though its included fasteners cover wood or metal doors 1-3/4 inch and 2-1/4 inch thick. On a 2-1/4 inch leaf where the device itself must be rated for the thickness, the Dormakaba 9300 is the 48 inch wide stile answer.
    15) What's a good alternative to the Von Duprin 99-4FT for a 48 inch door if I don't need the Von Duprin?
    At 48 inches with a wide stile push pad, the closest peers we carry are the Dexter ED1000 Series 4FT Grade 1 rim device and the Sargent 3828, a Grade 1 reversible push bar rim device for 48 inch doors, exit only. The Corbin Russwin ED3200 is Grade 1 wide stile at 48 inches but uses a crossbar rather than a push pad, and the CRL Jackson 1095 is a 48 inch crossbar wide stile device. If the budget is the driver rather than the spec, the Cal-Royal 5500 is a 48 inch wide push bar rim device at Grade 2. None of those carry the 98/99 option ecosystem, so if the door is getting electrified later, that trade matters more than the device cost.
    16) What's the difference between the Von Duprin 98 and 99 Series?
    Case appearance, on the same platform. The 99 has the grooved mechanism case, the 98 has the smooth case. Both share the heavy duty wide stile chassis, so specs, options, and mounting run the same across the two. Pick the 99 when the other openings in the building already wear grooved cases and you want the elevation to match.
    17) I need a 15 second delayed egress door. Can the Von Duprin 99 do that?
    Yes, with the CX CHEXIT option, which is a delayed egress build meeting NFPA and IBC requirements with a 15 second delay and a nuisance alarm. On the order form it shows as CXA, 15 second delay. If all you need is a local alarm on the door rather than delayed egress, the ALK alarm exit kit options are the lighter answer: ALK alone, RX-ALK with a request to exit switch, or LXRX-ALK with both LX and RX.
    18) What push bar options are there on the Von Duprin 99 for a tactile or low light exit?
    Beyond the standard bar, the 99 takes a BR braille pushbar, a KN knurled bar (the tactile warning surface code often calls for on a door leading to a hazardous area), an RSS emergency exit push bar, and an SG safety glow pushbar for low light or power loss visibility. There's also the QM quiet mechanical option if the device sits near occupied space and the latch noise matters.
    19) What is the difference between a Von Duprin 99-4FT and a Sargent 3828 for a 48 inch door?
    The Sargent 3828 is a Grade 1 reversible standard push bar rim exit device for 48 inch doors, wide stile, exit only. The Sargent 2828 is the Grade 1 reversible wide stile device for 48 inch minimum door width, also exit only. The Von Duprin 99-4FT is a 48 inch Grade 1 wide stile push pad device, non-handed in standard configuration, with a grooved mechanism case measuring 8 inch by 2-3/4 inch by 2-3/8 inch and a trim range that includes lever, knob, thumbpiece, night latch and dummy trim. The Sargent pair are exit only, so the deciding question is whether the opening needs keyed or lever entry from the outside.
    20) Is there a lighter duty 48 inch push bar exit device if a Grade 1 institutional device is more than the opening needs?
    The Cal-Royal 5500 is a 48 inch wide rim exit device with a push bar, rated Grade 2, heavy duty, and the Cal-Royal A9820 is a 48 inch exit-only rim device also rated Grade 2 heavy duty. Both are built to Grade 2 rather than the Grade 1 the Von Duprin 99-4FT carries, and both are described as exit only or push bar devices without the trim function range the 99 Series offers. On a low-traffic back-of-house or stockroom door where you only need code-compliant egress and no outside trim, either Cal-Royal covers the opening; on a school corridor or hospital door taking constant use, the Grade 1 platform is the one specified.
    21) What other Grade 1 wide stile rim exit devices come with hex key dogging like the Von Duprin 99?
    The Stanley Security QED200 Series device is a Grade 1 heavy duty rim exit device with hex key dogging, in a narrow stile configuration. The Design Hardware 1000R in 33 inch is a heavy duty rim device with hex key dogging, and the Design Hardware 2000R in 33 inch is a standard duty wide stile rim device also with hex key dogging. The Von Duprin 99-4FT ships with hex key dogging standard on a Grade 1 wide stile platform and also offers cylinder dogging, dogging with security indicator, special center case dogging and less-dogging configurations if the facility wants a keyed or monitored dogging arrangement instead of a hex key.
    22) What finish options does the Von Duprin 99 rim exit device come in for matching existing hardware?
    Twelve finishes, so a fleet match is usually possible: 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. For institutional corridors 630 satin stainless and 626 satin chrome are the usual specs; 628 aluminum matches storefront framing.
    23) What dummy exit device matches a Von Duprin 99 on the inactive leaf of a pair?
    The Detex Advantex 00 Series is a Grade 1 super-heavy-duty dummy exit device with wide stile design, and the Sargent 12-8810-LTRIM is a fire rated Grade 1 wide stile device in dummy function with RX and motorized electric latch retraction. The Von Duprin 99-4FT also offers DT dummy trim, K-DT and L-DT as ordered trim functions, which is the route to a matching grooved case and push pad appearance across both leaves of a pair.
