Heavy-Duty Fire-Rated Concealed Vertical Rod Exit Hardware for Institutional Wood Door Applications

Featuring a distinctive grooved mechanism case and a 48" push pad, this device is certified to ANSI/BHMA A156.3 2014 Grade 1 and UL listed for fire exit hardware per ANSI/UL 10C, making it a trusted choice for schools, hospitals, and government buildings. The 9947WDC-F-4ft is non-handed (except when the SS signal switch option is used), offers a 3/4" latch throw, and accommodates wood doors 1-3/4" thick 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

  • Door Thickness & Fastener Compatibility: Designed for wood doors 1-3/4" thick; fasteners included for wood or metal doors 1-3/4" and 2-1/4" thick, simplifying installation across common door preparations.
  • Non-Handed Configuration: The device is non-handed except when the SS (signal switch) option is selected, providing installation flexibility for a wide range of door configurations.
  • Field-Configurable & Retrofit-Ready: A variety of field-configurable options are available, including CDSI/HDSI security dogging indicators, QEL electronic latch retraction, and electronic switches (RX request-to-exit, LX latchbolt monitoring) for access control integration. Retrofit kits allow the device to keep pace with evolving technology.
  • Upgrade Options Available: Compatible with AX (ADA-compliant, certified to 5 lb. force per 2010 ADA Chapters 404.2.7 and 30934 and 2013 California Building Code Chapter 11B-309.4), CX (CHEXIT delayed egress meeting NFPA and IBC requirements, 15-second delay with nuisance alarm), and XP (patented 2-piece latchbolt design) upgrade configurations.

Von Duprin 9947WDC EO-F 4 US26D – Frequently Asked Questions

1) Is the 9947WDC-F fire rated, and what standards does it carry?
Fire rated, yes. The 9947WDC-F is certified to ANSI/BHMA A156.3 2014 Grade 1 and UL listed for fire exit hardware under ANSI/UL 10C, plus ANSI/UL 305, CAN/ULC-S104 and CAN/ULC-S132. That is why it comes less dogging: fire exit hardware cannot be held in the retracted position mechanically. If you need a dogged device for a non-rated opening, look at a non-fire version instead.
2) Does the 48 inch 9947WDC-F fit my door width, and how much does it stick out into the opening?
The 48 inch (4 ft) push pad size is sized for wide door openings, and the wide stile push pad needs a wide stile wood door. Projection off the door face is 3-13/16 inches, and the center case measures 8 x 2-3/4 x 2-3/8 inches. Check that 3-13/16 inches of projection against anything in the swing path, such as a facing wall or an adjacent door leaf.
3) Will a 3/4 inch latch throw work with a concealed vertical rod setup on a pair of doors?
Latch throw is 3/4 inch, top and bottom, which is what gives positive latching into the head strike and the floor or threshold strike. Because a concealed vertical rod device latches at the head and the sill rather than into a strike on the jamb, it secures a pair of doors without a center mullion. If you would rather keep a mullion and a simpler single latch, a rim device is the other way to do a pair.
4) Can the 9947WDC-F be tied into access control or an alarm?
Yes, and the switch and latch retraction options are ordering choices rather than field add-ons you have to source separately. Switch options include RX request to exit, LX latchbolt monitor, LX-RX combination, WP-RX waterproof RX, RX-LC low current, RX-2 double RX, SS signal switch, ALK alarm exit kit less switch, RX-ALK and LXRX-ALK. Latch retraction is available as EL electric, QEL quiet electric or PN pneumatic. Note that ordering SS makes the device handed.
5) Does the 9947WDC-F meet the 5 pound ADA operating force requirement?
Only if you order the AX accessible device option, which is certified to 5 lb. force per 2010 ADA Chapters 404.2.7 and 30934 and 2013 California Building Code Chapter 11B-309.4. AX is a required yes/no selection when ordering, so specify Yes where an accessible opening is called for on the drawings.
6) What is the closest fire-rated alternative to the Von Duprin 9947WDC-F-4ft concealed vertical rod device?
The Von Duprin 9947WDC-F-4ft is a Grade 1, fire-rated concealed vertical rod device with a wide stile push pad. The closest fire-rated wide stile concealed vertical rod peers are the Adams Rite 3600 Series and the Adams Rite 3900 Series, both Grade 1 fire-rated wide stile CVR devices, and the Sargent 12-MD8613, a Grade 1 fire-rated wide stile CVR in Classroom function. The Adams Rite 3600 is described for hollow metal doors, while the Von Duprin 9947WDC is built for wood doors 1-3/4 inch thick, so confirm the door substrate before swapping.
7) What should I use instead if my opening is a narrow stile aluminum or glass door rather than a wood door?
The Von Duprin 9947WDC-F-4ft is a wide stile device for wood doors 1-3/4 inch thick, so it will not suit a narrow stile aluminum opening. Narrow stile concealed vertical rod options include the Adams Rite 8600 Series for aluminum doors, the Corbin Russwin ED4800, a Grade 1 narrow stile CVR for 1-3/4 inch doors that accepts trim, and the DORMA 9600BB, a 36 inch Grade 1 narrow stile pushpad CVR for doors 1-3/4 inch to 2-1/4 inch. The Adams Rite 8600 and DORMA 9600BB are listed as non-fire-rated.
8) Is there a wide stile concealed vertical rod exit device made for wood doors other than the Von Duprin 9947WDC-F-4ft?
Yes. The BEST Precision 2701 Series is a wide stile reversible concealed vertical rod exit device for wood doors, which is the same door substrate the Von Duprin 9947WDC-F-4ft is engineered for. The Von Duprin unit is non-handed except with the SS signal switch option, while the 2701 is described as reversible. If the opening is a fire door, note that the 9947WDC-F carries a fire rating.
9) Is there a concealed vertical rod exit device with dogging, since the Von Duprin 9947WDC-F-4ft is less dogging?
The Von Duprin 9947WDC-F-4ft is supplied less dogging, which is normal for fire exit hardware. If the opening is not a fire door and you want mechanical dogging, the Sargent MD8613F-LTRIM is a heavy duty Grade 1 concealed vertical rod device for metal doors 36 inch by 84 inch with hex dogging. For fire openings, the Von Duprin can be ordered with CDSI or HDSI security dogging indicators and QEL quiet electric latch retraction instead.
10) Do I have to specify handing on a 9947WDC-F concealed vertical rod device?
The device is non-handed except when the SS signal switch option is ordered, in which case handing matters. Handing is still an ordering selection, RHR or LHR, so pick the one that matches the opening if you are adding a switch or handed trim.
11) What trim functions can I order with the Von Duprin 9947WDC-F?
Trim functions run from exit only through night latch and lockable trim: DT dummy trim, EO exit only, K knob, K-BE knob with blank escutcheon, K-NL knob night latch, L lever, L-BE lever with blank escutcheon, L-KC lever key capture, L-NL lever night latch, NL night latch, NL-OP night latch with optional pull, TL thumbturn, TL-BE thumbturn with blank escutcheon, TP thumbpiece and TP-BE thumbpiece with blank escutcheon. The 990 pull trim and 996 lever or knob trim cover Classroom, Storeroom, Dummy, Passage and Exit Only functions. If you choose an L trim, you also pick the lever design: 06 is the default, with 01, 02, 03, 05, 07, 17 and 18 also available.
12) What is the difference between the 9947WDC-F and the 9847WDC-F?
Mechanism case appearance. The 9947WDC-F has the grooved case of the 99 Series, while the 9847WDC-F is the smooth case 98 Series version. Performance is the same across the 98/99 platform, so the choice is architectural.
13) Can I get delayed egress on the Von Duprin 9947WDC-F?
Yes, through the CX CHEXIT upgrade, which provides a 15 second delay with nuisance alarm and meets NFPA and IBC requirements. The XP upgrade with the patented 2-piece latchbolt is also available if you are dealing with door pressure or forced-entry concerns on the same opening.
14) I only need exit-only hardware with no outside trim. What is comparable to the Von Duprin 9947WDC-F-4ft?
The Von Duprin 9947WDC-F-4ft can be ordered in an EO exit only trim function, but if you want a dedicated exit only device, the CRL Jackson 1085 Series is a 48 inch non-handed wide stile concealed vertical rod panic device in exit only function, matching the 48 inch size of the Von Duprin unit. The Corbin Russwin ED5800 is a Grade 1 wide stile CVR for 1-3/4 inch doors offered exit only or accepting trim. Confirm fire door requirements separately, as the 9947WDC-F is the fire-rated device here.
15) Is a crossbar concealed vertical rod device an equivalent to the Von Duprin 9947WDC-F-4ft push pad?
No. The Von Duprin 9947WDC-F-4ft uses a push pad style actuator on a wide stile device. The Corbin Russwin ED7800 is a Grade 1 narrow stile crossbar concealed vertical rod device for 1-3/4 inch doors, so it differs both in actuator style and stile width and will not drop into the same door prep. Choose the crossbar only where the specification calls for one.
16) I need a classroom function concealed vertical rod device on a fire door. How does the Sargent option compare to the Von Duprin 9947WDC-F-4ft?
The Sargent 12-MD8613 is a Grade 1 fire-rated wide stile concealed vertical rod device supplied in Classroom function. The Von Duprin 9947WDC-F-4ft is also Grade 1 and fire rated in a wide stile configuration, and its outside trim is selected separately across functions including lever, knob, night latch and thumbpiece, with 990 pull trim and 996 lever or knob trim available in Classroom, Storeroom, Dummy, Passage and Exit Only. The Von Duprin unit is built for wood doors 1-3/4 inch thick.
17) What finishes does the 9947WDC-F come in so I can match the other doors in the building?
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. For a school or hospital corridor standardizing on one look, 630 satin stainless and 628 aluminum are the usual institutional picks.
18) Are there push bar options for low light or visually impaired users on this exit device?
Yes. Beyond the standard bar, the 9947WDC-F can be ordered with a BR braille pushbar, a KN knurled bar, an RSS emergency exit push bar, or an SG safety glow pushbar. Knurled and braille bars are what facilities typically use to tactilely signal a hazardous or restricted exit.
19) Can the noise be reduced on this device for a hospital corridor?
Two options address it. QM Quiet Mechanical is a required yes/no ordering selection, and if you are electrifying the device, QEL quiet electric latch retraction is the low-noise alternative to standard EL. Both are worth specifying on patient care floors and near classrooms.
