Von Duprin 9948EO-F 4 US26 – Frequently Asked Questions

1) Will the Von Duprin 9948F fit a 4 foot opening, and what door thickness does it take?
The 9948F-4ft is built for a 48 inch door width and for doors 1-3/4 inches thick. That is a single thickness, not a range, so if your leaf is 1-3/8 or 2-1/4 inches the device case will not sit right. Fasteners come in the box for wood or metal doors 1-3/4 inch and 2-1/4 inch thick. Projection off the face of the door is 3-13/16 inches, which matters where the door swings into a corridor with limited clearance.
2) Is the Von Duprin 9948F fire rated, and why does it come less dogging?
It is fire rated, and that is exactly why there is no dogging. Fire exit hardware cannot be held in a latched-back position, so the device ships less dogging. It is ANSI/BHMA A156.3 2014 Grade 1 and UL listed under ANSI/UL 10C for fire exit hardware, along with CAN/ULC-S104, ANSI/UL 305 and CAN/ULC-S132. If you want a device you can dog open during business hours, you need a non-fire-rated exit device on a non-rated opening.
3) Does a concealed vertical rod exit device let me secure a pair of doors without a mullion?
Yes. A concealed vertical rod device latches at the head and at the threshold rather than into a strike on the frame edge, so a pair of doors can be secured with no center mullion and the full clear opening stays available. The 9948F does that with the rods and top/bottom latches hidden inside the door, so nothing is exposed on the face except the push pad case. If you would rather keep the hardware serviceable on the surface, a surface vertical rod device is easier to adjust in the field; if you can live with a mullion in the opening, a rim device is the simplest to install and maintain.
4) Can I get the 9948F with electric latch retraction or a request-to-exit switch for access control?
Yes, both are ordering options on the 9948F. Latch retraction comes as EL electric, QEL quiet electric, or PN pneumatic. Switch options include RX request to exit, LX latchbolt monitor, LX-RX combination, WP-RX waterproof, RX-LC low current, RX-2 double RX, SS signal switch, and three alarm exit kit builds (ALK, RX-ALK, LXRX-ALK). Specify these at order time, since they are built into the device.
5) Does the 9948F meet the 5 pound ADA operating force requirement?
Only if you order the AX accessible option. AX is certified to the 5 lb force requirement of 2010 ADA chapters 404.2.7 and 30934 and 2013 California Building Code chapter 11B-309.4. It is a yes/no selection when you build the part, so on an accessible route specify AX rather than assuming the standard device meets it.
6) What is the closest fire-rated wide stile concealed vertical rod alternative to the Von Duprin 9948F if Von Duprin is not an option?
The Von Duprin 9948F-4ft is a Grade 1 fire-rated concealed vertical rod device with a wide stile push pad. Two comparable fire-rated Grade 1 wide stile concealed vertical rod devices are the Adams Rite 3600 Series, listed for hollow metal doors, and the Adams Rite 3900 Series, which carries a 1-1/2 hour rating. On the Sargent side, the 12-MD8613 is a Grade 1 fire-rated wide stile concealed vertical rod device supplied in Classroom function. All three keep the fire rating and the Grade 1 designation; the Von Duprin remains the one supplied non-handed with a 3/4 inch latch throw and an 8 inch by 2-3/4 inch by 2-3/8 inch center case.
7) Which concealed vertical rod exit device should I use on an aluminum narrow stile door instead of the 9948F?
The 9948F-4ft is built on a wide stile push pad platform, so it is not the device for a narrow stile aluminum opening. For narrow stile, the Adams Rite 8600 Series is a Grade 1 narrow stile concealed vertical rod device specified for aluminum doors. Other narrow stile concealed vertical rod options include the Corbin Russwin ED4800, Grade 1 for 1-3/4 inch doors, and the DORMA 9600BB Series, a Grade 1 narrow stile pushpad device for 1-3/4 inch to 2-1/4 inch doors. Note the Adams Rite 8600 and the DORMA 9600BB are both listed non-fire rated, while the 9948F is fire rated.
8) I need a dogging feature on a concealed vertical rod device. Is the 9948F the right choice?
The 9948F-4ft is supplied less dogging, which is the correct configuration for a fire-rated opening. If the opening is not fire rated and you want mechanical dogging, the Sargent MD8613F-LTRIM is a heavy duty Grade 1 concealed vertical rod device for 36 inch by 84 inch metal doors supplied with hex dogging. Verify the code requirement for the opening before selecting a dogging device.
9) Do I have to specify a hand when ordering the 9948F?
The device itself is non-handed, so it works on single, double and double egress openings without a handing restriction. Handing is still selected on the order because trim and the switch options follow the door, and one exception applies: the SS signal switch option is handed. Right hand reverse and left hand reverse are the two choices.
10) Will the 9948F latch into my existing top and bottom strikes?
The latch throw is 3/4 inch. Concealed vertical rod hardware needs the top strike in the frame head and the bottom strike or threshold prep to match the device's own latch geometry, so a straight swap of strikes only works if the door was already prepped for a 98/99 Series CVR. Measure the existing prep before you commit; a different manufacturer's CVR prep will usually need new strikes.
11) What trim functions can I get with the Von Duprin 9948F?
Fifteen trim functions are offered: exit only, night latch, night latch with optional pull, knob, knob with blank escutcheon, knob night latch, lever, lever with blank escutcheon, lever key capture, lever night latch, thumbturn, thumbturn with blank escutcheon, thumbpiece, thumbpiece with blank escutcheon, and dummy trim. On lever trim you also pick the lever style: 06 is the default, with 01, 02, 03, 05, 07, 17 and 18 available. Exit only means no outside operation at all, which is the usual pick for a stair discharge or a rear egress door.
12) Can I get a delayed egress version of this Von Duprin device?
Yes, through the CX CHEXIT upgrade path, which provides a 15 second delay and meets NFPA and IBC delayed egress requirements. The XP upgrade is also available, a patented two-piece latchbolt design for openings that take abuse. Both are specified as upgrades to the 98/99 Series device rather than field-added afterthoughts.
13) The 9948F is not rated for wood doors. What concealed vertical rod device works on a wood door?
The Von Duprin 9948F-4ft is listed as not wood door compatible, though its fasteners cover wood or metal doors 1-3/4 inch and 2-1/4 inch thick. Where the opening itself is a wood door, the BEST Precision 2701 Series is a wide stile reversible concealed vertical rod device specified for wood doors. The BEST Precision 2801 Series is another wide stile concealed vertical rod option if you are standardizing on that platform.
14) What is a simpler exit-only concealed vertical rod device if I do not need the trim and switch options of the 9948F?
The 9948F-4ft accepts a wide range of trim functions and electrified switch options. If the opening only needs egress with no outside trim, exit-only concealed vertical rod devices include the BEST Precision 2601 Series, narrow stile and non-handed, the CRL Jackson 1085 Series in a 48 inch non-handed exit-only configuration, and the Falcon 24-C Series, a Grade 1 36 inch narrow stile exit-only device. The Corbin Russwin ED5800 is a Grade 1 wide stile device listed as exit only or accepting trim if you want to keep the wide stile format.
15) If the architect specified a crossbar rather than a push pad, what replaces the 9948F?
The 9948F-4ft is a push pad device. Where the drawing calls for a crossbar style touch bar on a concealed vertical rod device, the Corbin Russwin ED7800 is a Grade 1 narrow stile crossbar concealed vertical rod device for 1-3/4 inch doors that accepts operator trim. Confirm the stile width on the door, since the ED7800 is narrow stile and the 9948F is wide stile.
16) What concealed vertical rod option covers a 48 inch opening besides the Von Duprin 9948F?
The 9948F-4ft covers a 48 inch device size on a wide stile push pad. Another 48 inch concealed vertical rod option is the CRL Jackson 1085 Series, a 48 inch non-handed wide stile panic exit device in exit-only function. The CRL Jackson 1285 push pad concealed vertical rod is offered in narrow, medium or wide stile, also exit only. Both are exit-only devices, so where the 9948F is being ordered with lever, knob, or night latch trim the CRL devices do not carry that function.
17) Is a Falcon 1690EO or 1990EO a drop-in substitute for a Von Duprin 9948F?
Not for the same opening. The Falcon 1690EO and the Falcon 1990EO are both Grade 1 narrow stile concealed vertical rod exit-only devices for 1-3/4 inch doors, offered at 3 ft and 44 inch respectively. The Von Duprin 9948F-4ft is a 48 inch wide stile device that accepts trim and carries a fire rating. The stile type and the trim capability both differ, so the door prep and the function schedule need to be checked before substituting.
18) For the inactive leaf of a pair of doors, do I need a full 9948F or is dummy trim enough?
The 9948F-4ft is offered in a DT dummy trim function among its trim options, so it can be specified for an inactive leaf within the same series. A separate dummy alternative is the Falcon 1491DT, a Grade 1 narrow stile concealed vertical rod device in dummy function supplied with a 9970 pull at 42 inches. Match the stile type of the leaf: the Falcon is narrow stile and the 9948F is wide stile.
19) What finishes does the Von Duprin 9948F come in?
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 existing openings in a school or hospital, 626 and 630 are the two that usually turn up on institutional stock.
20) What push bar options are available, and which one should a school or transit facility pick?
Five bar choices on the 9948F: standard bar, BR braille push bar, KN knurled bar, RSS emergency exit push bar, and SG safety glow push bar. Knurled bar is the traditional tactile warning on doors leading to hazardous areas, and safety glow is the one to pick where egress paths need to be findable in smoke or a power loss. A QM quiet mechanical option is also selectable if noise on the opening is a concern, which matters in hospitals and libraries.
