The device is non-handed, offering flexible installation across a wide range of applications.

Von Duprin 9948EO-F 3 US26 – Frequently Asked Questions

1) Will the Von Duprin 9948F fit a 36 inch wide door, and what door thickness does it require?
The 9948F-3ft is sized for a 36 inch door opening and is built for 1-3/4 inch thick doors. It is a wide stile device, so it needs a door stile deep enough to take the wide mechanism case, which measures 8 x 2-3/4 x 2-3/8 inches. Projection off the face of the door is 3-13/16 inches, which matters if the door swings into a corridor with clearance limits. Mounting fasteners come in the box for wood or metal doors at 1-3/4 inch and 2-1/4 inch thickness.
2) Is the Von Duprin 9948F approved for a fire rated door assembly?
Yes. The 9948F is fire rated exit hardware, UL listed to ANSI/UL 10C and CAN/ULC-S104, and it also meets ANSI/UL 305 and CAN/ULC-S132. It is certified to ANSI/BHMA A156.3 2014 Grade 1. That combination is what a school, hospital, or municipal inspector looks for on a rated egress opening.
3) Why does the 9948F come less dogging, and can I add dogging to it?
It ships less dogging because it is fire exit hardware. Code does not permit mechanical dogging on a fire rated door assembly, since the latch has to stay projected to hold the door closed in a fire. If you need to hold a door in a push-pull condition during business hours, that has to be done on a non-rated opening with a dogging device, or electrically with the QEL quiet electric latch retraction option on this device.
4) Can I get the 9948F with request-to-exit or latch monitoring for my access control system?
Yes, several switch options are orderable: RX request to exit, LX latchbolt monitor, LX-RX combined, WP-RX waterproof RX, RX-LC low current RX, RX-2 double RX, SS signal switch, and alarm kits ALK, RX-ALK and LXRX-ALK. For remote unlocking, EL or QEL electric latch retraction or PN pneumatic retraction can be specified. CDSI/HDSI dogging indicator, QEL, RX and LX are also offered as retrofit kits if the need shows up after the device is installed.
5) Does the Von Duprin 9948F meet the 5 pound ADA operating force requirement?
Only with the AX accessible device option, which 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. AX is a selection made at order time, so specify it if the opening is on an accessible route.
6) What wide stile concealed vertical rod device works on a wood door, since the 9948F does not?
The Von Duprin 9948F-3ft is not wood door compatible. The BEST Precision 2701 Series is a wide stile reversible concealed vertical rod device specified for wood doors, and the BEST Precision 2801 Series is another wide stile concealed vertical rod option. The Corbin Russwin ED5800 is a Grade 1 wide stile concealed vertical rod device for 1-3/4 inch doors that accepts trim.
7) What other fire-rated wide stile concealed vertical rod exit devices match the Von Duprin 9948F in grade and rating?
The Von Duprin 9948F-3ft is a Grade 1 fire-rated concealed vertical rod device for wide stile doors. Two Adams Rite peers carry the same combination: the 3600 Series and the 3900 Series are both Grade 1, fire rated, and wide stile concealed vertical rod devices, with the 3900 Series rated for 1-1/2 hours. On the Sargent side, the 12-MD8613 is a Grade 1 fire-rated wide stile concealed vertical rod device supplied in Classroom function, so the trim behavior is fixed rather than selected the way the 9948F trim functions are.
8) Which concealed vertical rod exit device should I use on a narrow stile aluminum door instead of the 9948F?
The 9948F-3ft is built for wide stile doors, so a narrow stile aluminum opening needs a different device. The Adams Rite 8600 Series is a Grade 1 narrow stile concealed vertical rod device for aluminum doors. Other narrow stile Grade 1 options include the Corbin Russwin ED4800 and the Falcon 1690EO, both for 1-3/4 inch doors, and the Dormakaba 9600BB narrow stile pushpad device in a 36 inch size for doors 1-3/4 to 2-1/4 inch thick. The Adams Rite 8600, Dormakaba 9600BB, Corbin ED4800 and Falcon 1690EO are not fire rated devices, so confirm the opening is not a fire-rated assembly before specifying one.
9) Do I need to specify a hand for the Von Duprin 9948F?
The device itself is non-handed, so one device covers both swings. Handing is still selected when ordering (RHR or LHR) because trim and options follow the door, and the one exception called out is the SS signal switch, which does make the device handed. If you are stocking spares for a building with mixed swings, the non-handed case keeps the count down.
10) What is the difference between the Von Duprin 9948F and the 9848F?
Mechanically they are the same fire rated concealed vertical rod device. The difference is the case: the 9948-F uses a grooved mechanism case, the 9848-F a smooth case. It is an appearance choice, so match whatever is already on the neighboring openings in the building.
11) Should I use a concealed vertical rod exit device or a surface mounted one?
A concealed vertical rod device like the 9948F runs the rods inside the door, so nothing is exposed on the face and the door keeps a clean look. It latches top and bottom, which lets you secure a pair of doors without a center mullion. The tradeoff is that the door has to be prepped for concealed rods, which usually means ordering the door that way rather than retrofitting. A surface vertical rod is the choice on an existing door with no concealed prep, and a rim device with a removable mullion is simpler to service if the opening can take a mullion.
12) Will the 9948F latch into the strikes already in my frame and threshold?
The latch throw is 3/4 inch on the 9948F. Compare that against the strike depth at your head and threshold before reusing existing strikes; concealed vertical rod devices latch into a top strike at the frame head and a bottom strike or floor strike, and the rods are adjusted at install to get full 3/4 inch engagement.
13) What trim and lever options can I order with the Von Duprin 9948F?
Trim functions run from exit only (EO) and dummy trim (DT) through night latch (NL and NL-OP), knob functions (K, K-BE, K-NL), lever functions (L, L-BE, L-KC, L-NL), thumbturn (TL, TL-BE) and thumbpiece (TP, TP-BE). When you pick an L lever function you also choose the lever design: 01, 02, 03, 05, 06 (default), 07, 17 or 18. If the door is exit only with no outside operation, select EO and no lever.
14) Can I get delayed egress on a fire rated concealed vertical rod device?
Yes. The 9948F takes the CX CHEXIT upgrade, which holds the door for 15 seconds after a request to exit while a nuisance alarm sounds, and meets NFPA and IBC delayed egress requirements. That lets you run controlled access on a rated opening without giving up the fire listing.
15) If my door is not fire rated, do I still need the 9948F?
No, the F suffix is what makes it fire exit hardware, and on a non-rated opening you can use a device with dogging so the door can be held in push-pull during the day. Non-rated Grade 1 wide stile concealed vertical rod options include the Adams Rite 8500 Series for hollow metal doors and the DORMA 9100 Series wide stile pushpad device, which covers 1-3/4 to 2-1/4 inch doors.
16) Is there a simpler exit-only concealed vertical rod device if I do not need outside trim like the 9948F offers?
The 9948F-3ft is ordered with a trim function ranging from exit only through knob, lever, night latch, thumbturn and thumbpiece variants. If the opening needs no outside operation at all, exit-only peers include the BEST Precision 2601, a non-handed narrow stile concealed vertical rod device, the Falcon 24-C at 36 inches narrow stile Grade 1, and the CRL Jackson 1085 Series, a 48 inch non-handed wide stile exit-only unit. Those exit-only devices are not fire-rated hardware, so they suit non-rated openings; the 9948F is the fire-rated choice.
17) What can I use on a door thicker than 1-3/4 inches instead of the 9948F?
The Von Duprin 9948F-3ft lists a door thickness of 1-3/4 inches, though its fasteners are included for wood or metal doors 1-3/4 and 2-1/4 inches thick. If the opening is thicker, the Dormakaba 9100 Series is a Grade 1 heavy duty wide stile pushpad concealed vertical rod device specified for doors 1-3/4 to 2-1/4 inches, and the 9600BB covers the same thickness range in narrow stile. Both Dormakaba devices are non-fire-rated, so they apply only where the assembly is not fire rated.
18) What finishes does the Von Duprin 9948F exit device come in?
Twelve finishes are available: 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 and 626 are the usual matches to existing hardware.
19) What push bar styles are available on the Von Duprin 9948F?
Five bar options: standard bar, BR braille pushbar, KN knurled bar, RSS emergency exit push bar, and SG safety glow pushbar. Knurled bars are commonly specified where a tactile warning is wanted on a door leading to a hazardous area, and safety glow helps in a smoke or power-loss condition.
20) Is there a dummy trim concealed vertical rod option comparable to the 9948F DT configuration?
The 9948F-3ft can be ordered in a DT dummy trim function. As a separate part, the Falcon 1491DT is a 42 inch narrow stile concealed vertical rod dummy device supplied with a 9970 pull for 1-3/4 inch doors. The Falcon is narrow stile and 42 inches long, where the 9948F-3ft is a 36 inch wide stile device.
21) What concealed vertical rod device covers narrow, medium and wide stile openings if I do not want to match stile like the 9948F requires?
The Von Duprin 9948F-3ft is specified for wide stile doors only. The CRL Jackson 1285 push pad concealed vertical rod panic exit is listed for narrow, medium or wide stile applications and is an exit-only device, so it carries no outside trim function the way the 9948F trim options do.
