Von Duprin 9850WDCEO-F 4 643E – Frequently Asked Questions

1) Will the Von Duprin 9850WDCF fit a 4 foot wood door, and what door thickness does it need?
The 9850WDCF-4ft is built for 48 inch wide openings and a 1-3/4 inch door. That's a single thickness, not a range, so a 2-1/4 inch door leaf is outside what the device is specified for even though the fastener pack covers wood or metal doors at 1-3/4 inch and 2-1/4 inch. Projection off the face of the door is 3-13/16 inches, which matters if the door swings into a corridor with clearance limits.
2) Can I use the 9850WDCF on a fire rated wood door assembly in a school or hospital?
Yes. The 9850WDCF is fire rated and listed under ANSI/UL 10C and CAN/ULC-S104, with panic listings under ANSI/UL 305 and CAN/ULC-S132, and it is certified to ANSI/BHMA A156.3 2014 Grade 1. That combination is what an inspector looks for on a code-required fire door in an institutional building. One thing to keep in mind on fire doors: dogging is not permitted on a fire rated device, so the hex key dogging that ships standard should not be used to hold the latches retracted in a rated opening.
3) Does a concealed vertical cable device work on a pair of doors without a mullion?
It does. A concealed vertical device latches at the head and at the sill rather than into a strike on the jamb, so a pair of wood doors can be secured with no center mullion and you get a clear opening the full width of the pair. The 9850WDC is the cable version rather than rod, run inside the door leaf, so nothing is visible on the door face beyond the 48 inch smooth mechanism case and push pad. If you want a mullion-free pair with surface hardware instead, that's a surface vertical rod device, not this one.
4) Why is this device specified for wood doors instead of hollow metal?
The 50WDC concealed vertical cable configuration is purpose built for wood door construction, where a cable run tolerates the internal core and hardware reinforcement better than a rigid rod system. If your opening is hollow metal, look at a metal door concealed vertical device instead. From other brands ZenSupply carries, the Adams Rite 3600 Series is a fire rated Grade 1 wide stile concealed vertical rod device for hollow metal doors, and the Sargent MD8613F is a concealed vertical rod device for metal doors.
5) What is the difference between this and a narrow stile concealed vertical rod device?
The 9850WDCF is a wide stile device, sized for the broad stile of a wood or hollow metal door. Narrow stile devices are for aluminum storefront doors with a thin vertical stile and will not carry across. If your opening is aluminum storefront, the Adams Rite 8600 Series is a narrow stile concealed vertical rod device for aluminum doors, and Corbin Russwin ED4800 is a Grade 1 narrow stile concealed vertical rod for 1-3/4 inch doors. Neither of those two is listed as fire rated, so they are not a substitute on a rated opening.
6) What is the closest wood door alternative to the Von Duprin 9850WDCF-4ft concealed vertical rod exit device?
The BEST Precision 2701 Series is the nearest wood door peer. It is a wide stile concealed vertical rod exit device described as reversible for wood doors, matching the 9850WDCF-4ft on both stile type and wood door application. The Von Duprin unit is fire rated, uses a concealed vertical cable design for wood doors, and is non-handed except with special dogging or signal switch options, so on a fire door assembly the Von Duprin fire listing is the deciding detail.
7) I need a fire rated concealed vertical rod exit device but the doors are hollow metal, not wood. What should I use instead?
The 9850WDCF-4ft is built for wood doors, so for hollow metal openings look at the Adams Rite 3600 Series, a fire rated Grade 1 wide stile concealed vertical rod exit device for hollow metal doors. The Adams Rite 3900 Series is another fire rated Grade 1 wide stile concealed vertical rod option, carrying a 1-1/2 hour rating. Both keep the Grade 1 and fire rated attributes the Von Duprin carries while suiting metal door prep.
8) Do I have to specify a hand when I order the 9850WDCF?
The device itself is non-handed, so most orders don't turn on hand at all. Two exceptions: SD special center case dogging and SS signal switch are handed, and if you select either you have to call out RHR or LHR. Handing is still an order selection on the device, so pick the hand that matches the opening if you are taking a handed option.
9) What outside trim can I put on the 9850WDCF for a classroom or storeroom function?
It takes Von Duprin 990 pull trim and 996 lever or knob trim, in Classroom, Storeroom, Dummy, Passage and Exit Only functions. On the order you pick the trim function from a list that includes exit only, night latch, knob, knob with blank escutcheon, knob night latch, lever, lever with blank escutcheon, lever key capture, lever night latch, night latch with optional pull, thumbpiece, thumbpiece with blank escutcheon, and dummy trim. If you take an L lever trim, you also choose the lever design: 01, 02, 03, 05, 06, 07, 17 or 18.
10) Will the 9850WDCF latch into an existing top and bottom strike?
Latch throw is 3/4 inch. Compare that against the strike depth you already have at the head and threshold before you assume a straight swap, because a concealed vertical device has to engage both points to hold the door. Door prep also has to suit a center case of 8 x 2-3/4 x 2-3/8 inches on a 1-3/4 inch wood leaf.
11) What dogging and monitoring options do I need to pick when ordering this exit device?
Hex key dogging is the standard build. Alternatives are CD cylinder dogging, CDSI cylinder dogging with security indicator, HDSI hex dogging with security indicator, SD special center case dogging, LD less dogging, DI dogging indicator, and CI cylinder dogging indicator. Switch options are separate and optional: RX request to exit, LX latchbolt monitor, LX-RX combined, WP-RX waterproof RX, RX-LC low current, RX-2 double RX, SS signal switch, and ALK alarm kits with or without RX and LX. For access control you can add EL or QEL electric latch retraction or PN pneumatic. On a fire rated opening, LD or a dogging indicator option is the sensible call since dogging cannot be used there.
12) Can I add delayed egress to the 9850WDCF for a controlled exit?
Yes, through the CX CHEXIT upgrade. Configured that way, the device holds the door secure for 15 seconds after a request to exit while a nuisance alarm sounds, which is what NFPA and IBC call for in delayed egress. Other field upgrades the device accepts include QEL electronic latch retraction, RX and LX switches, the AX accessible device option, CDSI and HDSI security dogging indicators, and the XP two piece latchbolt.
13) Does the Von Duprin 9850WDCF come with mounting hardware or do I order fasteners separately?
Fasteners ship with the device, covering wood or metal doors at 1-3/4 inch and 2-1/4 inch thick. What is not in the box is the outside trim: if the opening needs a lever, knob, thumbpiece or pull on the exterior, that is a separate 990 or 996 trim selection, along with a cylinder for any keyed function such as night latch or classroom.
14) For standardizing a school or hospital on one concealed vertical rod device, how does the Von Duprin 9850WDCF-4ft compare to the wide stile alternatives?
Among the wide stile concealed vertical rod devices, the Von Duprin 9850WDCF-4ft, the Adams Rite 3600 and 3900 Series, and the Sargent 12-MD8613 are all Grade 1 and fire rated. The BEST Precision 2801 is a wide stile concealed vertical rod device, and the Corbin Russwin ED5800 is Grade 1 wide stile for 1-3/4 inch doors. The Von Duprin unit is the wood door member of that group and offers twelve finishes from bright brass through flat black for matching across a facility.
15) The opening is not a fire door. Is there a non-fire-rated concealed vertical rod device I can use in place of the Von Duprin 9850WDCF-4ft?
Yes. The DORMA 9100 Series is a Grade 1 heavy duty wide stile pushpad concealed vertical rod device listed as non fire rated, covering doors 1-3/4 inch to 2-1/4 inch thick. The Adams Rite 8500 Series is another non fire rated Grade 1 wide stile concealed vertical rod device for hollow metal doors. The Von Duprin 9850WDCF-4ft is fire rated and specified for 1-3/4 inch doors, so it remains the choice where a fire door assembly is involved.
16) Is there a wide stile concealed vertical rod exit device that takes lever trim like the Von Duprin 9850WDCF?
The Corbin Russwin ED5800 is a Grade 1 wide stile concealed vertical rod device for 1-3/4 inch doors offered as exit only or to accept trim. The Sargent 12-MD8613 is a Grade 1 fire rated wide stile concealed vertical rod device in classroom function. The Von Duprin 9850WDCF-4ft is ordered with trim functions including lever, lever night latch, lever key capture, knob, thumbpiece, night latch, dummy trim and exit only.
17) I only need an exit-only device at 48 inches with no outside trim. What are the options next to the Von Duprin 9850WDCF-4ft?
The CRL Jackson 1085 Series is a 48 inch non-handed wide stile concealed vertical rod panic device in exit only function. The CRL Jackson 1285 push pad concealed vertical rod exit is also exit only and covers narrow, medium or wide stile. The Von Duprin 9850WDCF-4ft can also be ordered EO exit only, and is non-handed except with special dogging or signal switch selections.
18) What finishes does the Von Duprin 9850WDCF come in for matching other hardware 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. Most institutional jobs standardize on 626 satin chrome or 630 satin stainless. Push bar options also let you match accessibility or wayfinding needs across a building: standard bar, BR braille, KN knurled (a tactile warning bar), RSS emergency exit push bar, and SG safety glow.
19) Is there an ADA compliant version of this Von Duprin exit device?
Yes, the AX accessible device option can be selected on the order, and AX is also available as a retrofit upgrade kit for devices already installed. For tactile and visibility requirements you can also spec a BR braille push bar or an SG safety glow push bar on the same device.
20) Is a crossbar concealed vertical rod device like the Corbin Russwin ED7800 a substitute for the Von Duprin 9850WDCF-4ft?
Not a like-for-like one. The ED7800 is a Grade 1 narrow stile crossbar concealed vertical rod device for 1-3/4 inch doors that accepts operator trim. The Von Duprin 9850WDCF-4ft uses push pads on a wide stile smooth case at 48 inches, so the actuation style and the stile prep both differ even though both are concealed vertical rod.
21) Which concealed vertical rod exit devices come in lengths other than 48 inches?
The Falcon 1990EO is a 44 inch narrow stile exit only concealed vertical rod device, the Falcon 24-C is a 36 inch narrow stile exit only device, the Falcon 1690EO is a 3 ft exit only unit, and the DORMA 9600BB is a 36 inch narrow stile pushpad device. The Von Duprin 9850WDCF-4ft covers the 48 inch wide stile position with a fire rating and Grade 1 certification.
