Von Duprin 9947EO 4 US26D – Frequently Asked Questions

1) Will the Von Duprin 9947 concealed vertical rod exit device work on a 1-3/4 inch hollow metal door?
Yes, 1-3/4 inches is exactly what the 9947 is built for. It is a single-thickness device, so the door thickness range is 1-3/4 inches only. Fasteners ship in the box for wood or metal doors 1-3/4 inches and 2-1/4 inches thick, but the device itself is specified at 1-3/4. On a thicker door or a wood door, look elsewhere: the 9947 is not rated wood door compatible. The DORMA 9100 Series wide stile concealed vertical rod device covers 1-3/4 to 2-1/4 inches, and the BEST Precision 2701 Series is a wide stile reversible concealed vertical rod device for wood doors.
2) Is the Von Duprin 9947 exit device fire rated?
No. The 9947 is a non-fire-rated concealed vertical rod device, so it cannot go on a labeled fire door assembly. If the opening needs a fire label, the Adams Rite 3600 Series and 3900 Series are both fire-rated Grade 1 wide stile concealed vertical rod devices for hollow metal doors, and the Sargent 12-MD8613 is a fire-rated Grade 1 wide stile CVR in classroom function. Note that a fire-rated exit device cannot be dogged, which is why the hex key dogging on the 9947 is available in the first place.
3) Do I have to specify handing on a Von Duprin 9947 concealed vertical rod device?
The 9947 is non-handed as a base device, so a standard order goes on either a right hand reverse or left hand reverse opening. Handing only becomes a real requirement when you add SD (special center case dogging) or SS (signal switch). Because those options exist on the order form, handing is asked for at order time as RHR or LHR, so have the door hand ready even if the base mechanism does not care.
4) What is the difference between wide stile and narrow stile on a concealed vertical rod exit device?
The 9947 is a wide stile device with a push pad, and its center case measures 8 x 2-3/4 x 2-3/8 inches. That case needs a stile wide enough to carry it, which is why wide stile devices go on hollow metal and wood doors rather than narrow aluminum storefront stiles. On an aluminum entrance with a narrow stile, use a narrow stile CVR instead: the Adams Rite 8600 Series is a narrow stile concealed vertical rod device for aluminum doors, and the Corbin Russwin ED4800 is a Grade 1 narrow stile CVR. The CRL Jackson 1285 push pad CVR is listed for narrow, medium or wide stile.
5) Will the 9947 latch reliably into my existing top strike?
The 9947 throws its latch 3/4 of an inch, with a 5/8 inch bottom bolt on the 47 suffix. Three quarters of an inch is a full commercial throw, so it engages a standard top strike with margin for a door that has settled or a frame with some rack in it. If you are matching an existing prep, the depth of engagement your old strike was cut for is what to verify against that 3/4 inch figure. The Pullman latch option (PL top and bottom) changes the latch style, and on a less bottom rod order the ES top Pullman latch is what goes in for an electric strike application.
6) What do I have to specify when ordering a Von Duprin 9947, beyond the size and finish?
Six decisions carry the order. Trim function, from 17 choices including EO exit only, NL night latch, L lever, K knob, TP thumbpiece, TL thumbturn and the blank escutcheon and dummy trim variants; if you pick an L function, you also pick the lever design (01, 02, 03, 05, 06, 07, 17 or 18, with 06 as the default). Handing, RHR or LHR. Dogging, with hex key as standard and CD cylinder dogging, CDSI, HDSI, SD, LD less dogging, DI and CI as alternates. Finish, from 12. Push bar style, standard or BR braille, KN knurled, RSS emergency exit, SG safety glow. Then the electrical and switch options if the opening is access controlled.
7) Can the Von Duprin 9947 be tied into an access control system with electric latch retraction?
Yes. Latch retraction is orderable as EL electric latch retraction, QEL quiet electric latch retraction, or PN pneumatic. On the monitoring side you can add RX request to exit, LX latchbolt monitor, LX-RX combined, RX-2 double RX, RX-LC low current, WP-RX waterproof RX, or SS signal switch, plus the ALK alarm exit kit variants (ALK less switch, RX-ALK, LXRX-ALK). QEL, RX and LX are also offered as retrofit kits, so a device already hung can be upgraded later rather than replaced. Specifying SS at order time does make the device handed.
8) Does the Von Duprin 9947 meet ADA push force requirements?
Only with the AX option, which is a yes or no choice at order time. AX is certified to the 5 pound force requirement of 2010 ADA Chapters 404.2.7 and the 2013 California Building Code Chapter 11B-309.4. Order the base device without AX and you do not get that certification, so on an accessible route or a California job the AX box needs ticking.
9) The 9947 will not work on my narrow stile aluminum storefront door - what concealed vertical rod device should I use instead?
The Von Duprin 9947 is a wide stile device, so on a narrow stile aluminum door the Adams Rite 8600 Series is the direct alternative - a narrow stile concealed vertical rod exit device built for aluminum doors. Other narrow stile concealed vertical rod choices include the Corbin Russwin ED4800, a Grade 1 narrow stile device for 1-3/4 inch doors offered exit only or accepting trim, and the Falcon 1690EO, a Grade 1 narrow stile exit only device for 1-3/4 inch doors. If a crossbar rather than a push pad suits the opening, the Corbin Russwin ED7800 is a Grade 1 narrow stile crossbar concealed vertical rod device.
10) I need a concealed vertical rod exit device on a wood door - is the 9947 the right choice?
The Von Duprin 9947 is listed as not wood door compatible, so for a wood door the BEST Precision 2701 is the one to look at: a wide stile reversible concealed vertical rod exit device built for wood doors in the 2700 Series. It keeps the same wide stile concealed vertical rod arrangement the 9947 uses, on the door material the job actually has.
11) Should I use a concealed vertical rod exit device or a surface vertical rod on a pair of metal doors?
Concealed vertical rod, which is what the 9947 is, runs the rods inside the door stile and latches at the head and threshold with nothing exposed on the door face. That is the choice when appearance matters (school and hospital corridors, government lobbies) and when you want the rods protected from abuse and from being kicked. It requires a door prepped for concealed rods, so it is a specify-at-the-door decision, not a field retrofit onto a plain door. Surface vertical rod mounts entirely on the door face and can go on an existing unprepped door, which makes it the practical pick for replacement work. A rim device with a removable mullion is the other route on a pair, and it moves the latching to the mullion instead of the head and sill.
12) Which dogging option should I pick for a school corridor where staff hold doors open during the day?
Hex key dogging is the standard configuration on the 9947 and it gives you push pad holdback with a hex wrench, which is fine where only maintenance touches it. In a school where staff dog and undog doors on a schedule, CD cylinder dogging is the usual upgrade because it takes a key instead of a loose wrench. If a lockdown policy means someone has to see at a glance whether a door is dogged, CDSI (cylinder dogging with security indicator) or HDSI (hex dogging with security indicator) add a visual indicator, and DI and CI cover dogging indicator and cylinder dogging indicator. LD (less dogging) is the order when policy is that the door never gets held open.
13) Can I set up delayed egress on a Von Duprin 9947 for a hospital or memory care unit?
Yes, through the CX CHEXIT upgrade. It holds the door secure for 15 seconds after a request to exit while a nuisance alarm sounds, and it meets NFPA and IBC requirements for delayed egress. That covers behavioral health wings, memory care and infant security areas where you need to slow an exit without blocking it. Delayed egress is also an AHJ conversation, so the 15 second delay is the figure to bring to them.
14) I need a lever handle on the outside of the door. Which 9947 trim function do I order?
Order an L function and then pick the lever design. L is lever with no cylinder function, L-NL is lever with night latch (key retracts the latch for entry), L-KC is lever with key capture, L-BE is lever with a blank escutcheon and L-DT is lever with dummy trim for a pull-only leaf. The lever design itself is a separate required choice: 01, 02, 03, 05, 06, 07, 17 or 18, with 06 as the default. On a classroom or office door where the outside handle should stay locked until keyed, L-NL is the common pick; on the inactive leaf of a pair, L-DT or plain DT dummy trim.
15) What is the closest Grade 1 wide stile concealed vertical rod alternative to the Von Duprin 9947?
Straight across, the Corbin Russwin ED5800 is the nearest equal: Grade 1, wide stile concealed vertical rod, 1-3/4 inch door thickness, exit only or accepts trim, same as the 9947's 1-3/4 inch specification. The DORMA 9100 Series is the other wide stile Grade 1 CVR push pad device and it takes a wider door, 1-3/4 to 2-1/4 inches. Adams Rite 8500 Series is a Grade 1 wide stile CVR for hollow metal doors, also non-fire-rated like the 9947. Where those differ from the 9947 is in the option breadth: the 204 combinations of trim, dogging, switch and bar style on the Von Duprin is the reason it gets specified on institutional work.
16) I only need push to exit with no outside trim. Is there a cheaper concealed vertical rod device than the 9947?
If the leaf is exit only, order the 9947 in EO trim function and you skip the outside trim entirely. Simpler devices exist if you do not need the option range: the CRL Jackson 1085 Series is a 48 inch non-handed wide stile CVR panic device in exit only function, the same 48 inch size as the 9947-4ft. BEST Precision 2801 Series is a wide stile CVR, and 2601 is narrow stile exit only, non-handed. The trade-off is that an exit only device cannot later take a lever or night latch without changing the device, so if the door might ever need keyed entry, order the 9947 with a trim function now.
17) What is the Von Duprin 9947 less bottom rod option, and when do I need it?
Less bottom rod drops the bottom latching point so nothing engages the threshold. It is the order on openings where floor debris, snow melt, carpet or an uneven slab would foul a bottom bolt, and in kitchens and wash-down areas where you do not want a bolt hole in the floor. When you order less bottom rod, the top latch changes: the ES top Pullman latch is the option for less bottom rod with an electric strike application, and the standard PL top and bottom Pullman latch pairing does not apply. Understand that giving up the 5/8 inch bottom bolt means all the security is at the head.
18) Which concealed vertical rod devices besides the Von Duprin 9947 handle doors thicker than 1-3/4 inch?
The Von Duprin 9947 carries a door thickness of 1-3/4 inch, though its fasteners are included for wood or metal doors 1-3/4 inch and 2-1/4 inch thick. Among the comparable devices, the Dormakaba DORMA 9100 states a door thickness range of 1-3/4 inch to 2-1/4 inch in a Grade 1 heavy duty wide stile pushpad configuration, and the DORMA 9600BB states the same 1-3/4 inch to 2-1/4 inch range in a narrow stile pushpad at 36 inches. Both are non-fire-rated, as the 9947 is.
19) Is the Falcon 1491DT a substitute for a Von Duprin 9947?
No - the Falcon 1491DT is a dummy function device. It is a narrow stile concealed vertical rod unit with a 9970 pull at 42 inches, and dummy function means it does not latch or provide code egress; it is used for the inactive side of a pair to match appearance. The Von Duprin 9947 is a working panic device with a 3/4 inch latch throw and hex key dogging. If a matching inactive leaf is what is needed alongside a live device, the 9947 itself is also ordered in DT dummy trim and blank escutcheon functions.
20) We want to standardize our schools on one concealed vertical rod exit device with lever trim and hex dogging - what are the Grade 1 candidates?
The Von Duprin 9947 is Grade 1, non-handed except when special dogging or a signal switch is chosen, ships with hex key dogging as standard, and is ordered with lever trim in a range of lever designs. The Sargent MD8613F-LTRIM is a Grade 1 heavy duty 80 Series concealed vertical rod device for metal doors at 36 by 84 inches with hex dogging and lever trim. On the wide stile side, the Corbin Russwin ED5800 is Grade 1 for 1-3/4 inch doors and accepts trim, and the Dormakaba DORMA 9100 is a Grade 1 heavy duty wide stile pushpad device.
21) I need a 36 inch concealed vertical rod device rather than a 48 inch - what are my options?
The Von Duprin 9947 covered here is a 48 inch product size. For a shorter opening, the Falcon 24-C is a Grade 1 narrow stile exit only concealed vertical rod device at 36 inches for 1-3/4 inch doors, the Falcon 1690EO is a Grade 1 narrow stile exit only device at 3 ft, and the Dormakaba DORMA 9600BB is a 36 inch non-fire-rated Grade 1 narrow stile pushpad device. The Sargent MD8613F-LTRIM is sized for metal doors 36 by 84 inches with hex dogging.
22) What finishes does the Von Duprin 9947 come in for matching existing hardware across a 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 matching a fleet of existing openings, 630 satin stainless and 626 satin chrome are the two that read closest to most institutional door hardware already in the field, and 628 aluminum is what pairs with clear anodized aluminum entrances. Standardize on the finish number, not the description, since the BHMA number is what carries across brands.
23) Is there a quieter version of the Von Duprin 9947 for a hospital corridor or a library?
Two options address noise. QM (quiet mechanical) is a yes or no choice on the base device and quiets the mechanical action. If the door is access controlled, QEL (quiet electric latch retraction) replaces standard EL and is the quiet option for motorized retraction. Both matter in patient care corridors, testing centers and libraries where a panic device slamming its latches carries down the hall. QEL is also available as a retrofit kit, so an existing 98/99 device can be quieted without a full replacement.
24) Can I get a braille or glow-in-the-dark push bar on the Von Duprin 9947?
Yes, the push bar style is a required choice and there are five: standard bar, BR braille push bar, KN knurled bar, RSS emergency exit push bar and SG safety glow push bar. BR and KN are the tactile options that come up on accessibility-driven specs, and SG is the one specified for stairwells and egress paths where the bar has to be findable in a power outage or smoke condition. Pick this at order time; it is not a field-swappable part of the order.
25) What is the XP option on a Von Duprin 9947, and is it worth adding on an abuse-prone door?
XP is a patented two-piece latchbolt design, offered as an upgrade on the 9947. It is the option to add where doors get attacked or pried, which is the same reasoning behind putting a Grade 1 device on the opening in the first place. On a high-abuse door (a school exterior, a loading area, a public restroom corridor) the latchbolt is the part that takes the load, so upgrading it is the cheapest way to get more life out of the device.
26) Are there non-handed concealed vertical rod exit devices comparable to the Von Duprin 9947?
The Von Duprin 9947 is non-handed, with handing required only when special dogging or a signal switch is selected. Among comparable devices, the BEST Precision 2601 is a non-handed narrow stile concealed vertical rod device in exit only function, the BEST Precision 2701 is a wide stile reversible unit for wood doors, and the CRL Jackson 1085 is a 48 inch non-handed wide stile concealed vertical rod panic device in exit only function.
27) Do any concealed vertical rod alternatives come pre-set in classroom function instead of being configured with trim?
The Sargent 12-MD8613 is a Grade 1 wide stile fire rated concealed vertical rod exit device supplied in classroom function. The Von Duprin 9947 instead reaches its outside operation through the trim function chosen at order - knob, lever, night latch, thumbturn, thumbpiece, key capture and blank escutcheon variants among them - so the function is built from the trim selection rather than named as a single catalog function.
