Heavy-Duty Concealed Vertical Cable Panic Exit Hardware for Single and Double Wood Doors

The Von Duprin 9850WDC-4ft is a 48" wide stile concealed vertical cable exit device engineered specifically for single or double wood doors, featuring a smooth mechanism case that distinguishes it from the grooved-case 9950WDC. Certified to ANSI/BHMA A156.3 2014 Grade 1 and UL listed for panic exit hardware, this device delivers institutional-grade reliability for demanding applications including schools, hospitals, and government facilities. The non-handed design simplifies installation across a wide range of configurations, and fasteners are included for wood or metal doors 1-3/4" thick. With a 3/4" latch throw, 8" x 2-3/4" x 2-3/8" center case dimensions, and a product projection of 3-13/16", this device is built to perform in high-traffic commercial environments.

  • Non-Handed Configuration: The device is non-handed except when SD (special dogging) or SS (signal switch) options are selected, simplifying inventory management and installation planning.
  • Included Fasteners: Fasteners are included for wood or metal doors 1-3/4" and 2-1/4" thick, supporting straightforward installation without additional hardware procurement.

Von Duprin 9850WDCEO 4 US26D – Frequently Asked Questions

1) What door thickness does the 9850WDC exit device fit, and are the screws included?
It is set up for 1-3/4 inch doors, the standard commercial thickness. Fasteners ship with the device for wood or metal doors 1-3/4 inch and 2-1/4 inch thick, so no separate hardware pack is needed for a normal install.
2) Does the 9850WDC need to be ordered handed?
It's non-handed as standard, so one part number covers both hands. Two exceptions: if you specify SD (special center case dogging) or SS (signal switch), the device becomes handed and you must call out RHR or LHR.
3) How do I hold the doors unlatched during business hours?
Hex key dogging is standard, so the pad can be held down and the latches retracted for free push/pull traffic. Other dogging choices on the order form include CD cylinder dogging, CDSI cylinder dogging with a security indicator, HDSI hex dogging with indicator, DI or CI dogging indicators, SD special center case dogging, and LD less dogging if the job calls for no dogging at all.
4) What outside trim can I get with the Von Duprin 9850WDC?
Trim functions run from exit only (EO) and dummy trim through knob, lever, and thumbpiece sets: K, K-BE, K-DT, K-NL, L, L-BE, L-DT, L-KC, L-NL, NL, NL-OP, TP and TP-BE. If you choose an L lever function you also pick the lever design: 01, 02, 03, 05, 06 (default), 07, 17 or 18.
5) Can I tie this exit device into an access control system?
Yes. Electric latch retraction is available as EL, QEL quiet electric latch retraction, or PN pneumatic. For monitoring, switch options include RX request to exit, LX latchbolt monitor, LX-RX combination, RX-2 double RX, RX-LC low current, WP-RX waterproof, SS signal switch, and ALK alarm kits with or without RX and LX. CX/CHEXIT delayed egress is also an upgrade path, holding the door 15 seconds with a nuisance alarm.
6) Does the 9850WDC meet ADA push force requirements?
Only if you order the AX accessible option. AX is ADA certified to the 5 lb force requirement per 2010 ADA Chapters 404.2.7 and 30934 and 2013 California Building Code Chapter 11B-309.4. It is a yes/no selection at order time, so it has to be called out.
7) Can this secure a pair of doors without a mullion?
Yes. As a concealed vertical cable device the 9850WDC latches at the head and at the floor rather than into a jamb strike, so a pair of wood doors can be secured with no center mullion. Von Duprin lists it for single or double wood doors.
8) The opening is a fire-rated wood pair - can the Von Duprin 9850WDC-4ft be used there?
No. The 9850WDC-4ft carries a fire rating of No, so it is a panic-only device for non-fire openings. For a fire-rated concealed vertical rod opening, the Adams Rite 3900 Series is fire rated with a 1-1/2 hour rating and the Adams Rite 3600 Series is a fire-rated wide stile concealed vertical rod device; the Sargent 12-MD8613 is a fire-rated Grade 1 wide stile concealed vertical rod device in classroom function.
9) What is the closest wide stile concealed vertical rod equivalent to the Von Duprin 9850WDC-4ft from another maker?
Comparable wide stile Grade 1 concealed vertical rod push pad devices include the DORMA 9100 Series, which is a heavy duty Grade 1 wide stile pushpad device for doors 1-3/4 inch to 2-1/4 inch thick, the Corbin Russwin ED5800 Grade 1 wide stile concealed vertical rod device for 1-3/4 inch doors in exit only or trim-accepting configurations, and the Adams Rite 8500 Series, a non-fire-rated Grade 1 wide stile concealed vertical rod device for hollow metal doors. The 9850WDC-4ft itself is a Grade 1 wide stile push pad device with a 3/4 inch latch throw for 1-3/4 inch doors.
10) My doors are narrow stile aluminum storefront - what concealed vertical rod device should I use instead of the 9850WDC-4ft?
The 9850WDC-4ft is a wide stile device and will not fit a narrow aluminum stile. For narrow stile aluminum doors, the Adams Rite 8600 Series is a narrow stile concealed vertical rod device built for aluminum doors; other narrow stile options include the Corbin Russwin ED4800 Grade 1 narrow stile device for 1-3/4 inch doors and the DORMA 9600BB Series narrow stile pushpad in a 36 inch size.
11) Will the 9850WDC latch into my existing strike?
The latchbolt throws 3/4 inch, which is the standard projection for this class of device. Because it's a concealed vertical cable device it latches top and bottom rather than into the jamb, so the top strike at the head and the bottom strike or threshold prep are what have to line up, not a side strike.
12) How far does this exit device stick out from the door face?
Projection is 3-13/16 inches with the center case measuring 8 x 2-3/4 x 2-3/8 inches. That matters in tight corridors, at door swings near a wall, and where the push pad has to clear a pull side handrail or adjacent fixture.
13) Should I pick a concealed vertical rod device or a surface mounted one?
Concealed vertical cable, like the 9850WDC, hides the rods inside the door so there is nothing exposed to grab, kick, or vandalize, which is why it gets specified in schools, hospitals, and government work. The trade off is that the door has to be prepped for it, so it's easiest to plan on a new wood door or a factory prepped leaf. Surface vertical rod is the better call when you're retrofitting an existing unprepped door.
14) What is the difference between the Von Duprin 9850WDC and the 9950WDC?
Mechanism case appearance. The 9850WDC has a smooth case; the 9950WDC is the grooved case version. Both are wide stile concealed vertical cable devices in the 98/99 Series, so the choice is aesthetic matching across your openings rather than function.
15) Is this device rated for heavy traffic in a school or hospital?
It is certified to ANSI/BHMA A156.3 2014 Grade 1, the top grade for exit devices, and carries ANSI/UL 305 and CAN/ULC-S132 panic listings. That's the specification level institutional facilities standardize on for high use egress openings.
16) Can I use the Von Duprin 9850WDC-4ft on a hollow metal door instead of wood?
The 9850WDC-4ft is built for wood doors and supplies fasteners for wood or metal doors 1-3/4 inch and 2-1/4 inch thick. Where the opening is hollow metal, devices catalogued for that substrate include the Adams Rite 8500 Series concealed vertical rod device for hollow metal doors, the Adams Rite 3600 Series fire-rated version for hollow metal, and the Sargent MD8613F-LTRIM, a heavy duty Grade 1 device for metal doors 36 inch by 84 inch with hex dogging.
17) I only need exit only with no outside trim - is there a simpler alternative to the 9850WDC-4ft?
Yes. The 9850WDC-4ft is ordered with a trim function selection that ranges from EO exit only through knob, lever, thumbpiece and night latch options. If the opening needs nothing on the outside, dedicated exit only concealed vertical rod devices include the CRL Jackson 1085 Series, a 48 inch non-handed exit only panic device, the BEST Precision 2601 Series exit only non-handed device, and the Falcon 1990EO in a 44 inch length.
18) My wood doors are 2-1/4 inch thick - does the 9850WDC-4ft still work, or should I look elsewhere?
The 9850WDC-4ft lists a door thickness of 1-3/4 inch, and fasteners are supplied for wood or metal doors 1-3/4 inch and 2-1/4 inch thick. If you want a device catalogued across that full thickness band, the DORMA 9100 Series wide stile pushpad and the DORMA 9600BB narrow stile pushpad are both listed for 1-3/4 inch to 2-1/4 inch doors.
19) I need classroom function on a concealed vertical rod exit device - does the 9850WDC-4ft cover that?
The 9850WDC-4ft is ordered by trim function from a list that includes exit only, knob, lever, night latch, key capture and thumbpiece variations rather than a named classroom function. If classroom function is written on the drawing, the Sargent 12-MD8613 is a Grade 1 wide stile concealed vertical rod device specified in classroom function and fire rated.
20) I need a 36 inch concealed vertical rod device, not 48 inch - what are the options?
The 9850WDC-4ft is a 48 inch device. Shorter concealed vertical rod devices include the Falcon 24-C Series at 36 inches in narrow stile exit only, the Falcon 1690EO narrow stile at 3 ft exit only, and the DORMA 9600BB Series at 36 inches in narrow stile pushpad. Note that those are narrow stile, so check stile width against the door before ordering.
21) What finishes does the 9850WDC 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. 626 and 630 are the usual institutional matches.
22) Can I get a tactile or high visibility push bar on this device?
Yes, the bar is a selection. Beyond the standard bar you can order BR braille pushbar, KN knurled bar, RSS emergency exit push bar, or SG safety glow pushbar. Knurled bars are commonly used where a tactile warning is wanted on a hazardous door.
23) What is the XP option on the Von Duprin 98/99 devices?
XP is a patented 2-piece latchbolt design offered as an upgrade on the 9850WDC. It's specified where doors see heavy abuse or attempted forced entry at the latch.
24) Which concealed vertical rod devices fit stiles of varying width if I am standardizing across mixed openings?
The Von Duprin 9850WDC-4ft is a wide stile device only. For a mixed set of openings, the CRL Jackson 1285 push pad concealed vertical rod exit device is catalogued for narrow, medium or wide stile, while the BEST Precision 2801 Series covers wide stile openings. Confirm stile width and door prep at each opening before committing to one model across the building.
