Von Duprin 5547WDC-4ft Concealed Vertical Rod Exit Device for 4ft Narrow Stile Wood Doors

Classic Crossbar Design with Concealed Vertical Rod Technology for Wood Door Applications

The Von Duprin 5547WDC-4ft is a 4-foot (48") Concealed Vertical Rod Exit Device engineered for single or double wood door applications requiring a narrow stile crossbar solution.

The device is field reversible for door hand direction and features Hex Key Dogging for convenient hold-open functionality.

Von Duprin 5547-WDC EO US26D-4 – Frequently Asked Questions

1) Will the Von Duprin 5547WDC fit a wood door with only a 4 inch stile?
Yes. The 5547WDC is a narrow stile device built to work on stiles as narrow as 4 inches (102 mm), which is why it gets specified on wood doors with glass lights or slim rails where a wide stile device has nowhere to mount. Door thickness has to be 1-3/4 inches, and the crossbar projects 3-3/4 inches off the face of the door, so allow for that in a corridor or where the door swings against a wall.
2) Is the Von Duprin 5547WDC-4ft fire rated?
As catalogued, no. The 5547WDC-4ft is a panic device certified to ANSI/BHMA A156.3 2008 Grade 1 with ANSI/UL 305 and CAN/ULC-S132 panic listings, but it is not a fire door assembly device. A fire rated version of the 55 Series is ordered by adding the -F suffix to the model, which brings ANSI/UL 10C and CAN/ULC-S104 compliance. If your opening is a labeled fire door, order the -F. Note also that hex key dogging is a panic-only feature; fire rated exit devices cannot be dogged open.
3) Do I have to order the 5547WDC handed, or can it be reversed in the field?
Door hand on the 5547WDC is field reversible, so the chassis itself does not lock you into one swing. You still pick LHR or RHR when ordering, along with the finish, trim function and crossbar option, but if the opening turns out opposite to what was on the drawing the device can be re-handed on site rather than returned.
4) What do I need to specify when ordering a Von Duprin 55 Series concealed vertical rod device?
Four decisions beyond the device size. Trim function: DT dummy trim, EO exit only, L lever, L-BE lever with blank escutcheon, NL night latch, NL-OP night latch cylinder with optional pull, TL thumb turn, or TL-BE thumb turn with blank escutcheon. If you pick a lever function, choose the lever style (06 is the default, with 03, 07 and 17 also offered). Handing, LHR or RHR. Crossbar: standard, RCB reinforced, or KN knurled. Then finish, and whether you want the RX request to exit switch built in.
5) What are the alternatives if my doors are aluminum or hollow metal instead of wood?
The 5547WDC is built for wood door applications. For narrow stile aluminum, the Adams Rite 8600 Series is a narrow stile concealed vertical rod device, and the Corbin Russwin ED4800 is a Grade 1 narrow stile concealed vertical rod for 1-3/4 inch doors. For hollow metal, look at the Adams Rite 8500 Series (wide stile, non-fire-rated) or the Adams Rite 3600 Series if the opening is a labeled fire door. Sargent's MD8613F is a concealed vertical rod device for metal doors with hex dogging.
6) What is the closest crossbar concealed vertical rod alternative to the Von Duprin 5547WDC-4ft?
The Corbin Russwin ED7800 is the nearest match in style. Like the Von Duprin 5547WDC-4ft, it is a Grade 1 narrow stile concealed vertical rod exit device built around a crossbar rather than a push pad, and it is listed for 1-3/4 inch doors, the same door thickness the 5547WDC-4ft covers. The ED7800 is an exit only device that accepts operator trim, while the 5547WDC-4ft is ordered with the trim function built into the configuration, including Lever, Night Latch, Thumb Turn, Dummy Trim and Exit Only.
7) My door is aluminum, not wood. Is the Von Duprin 5547WDC-4ft still the right device?
The 5547WDC-4ft is built for narrow stile wood door applications. For an aluminum storefront leaf, the Adams Rite 8600 Series is a Grade 1 narrow stile concealed vertical rod device specifically for aluminum doors, and the CRL Jackson 1285 push pad concealed vertical rod exit is offered for narrow, medium or wide stile. Both are narrow stile compatible like the 5547WDC-4ft, so the stile width itself is not what changes.
8) Which concealed vertical rod devices look like substitutes for the Von Duprin 5547WDC-4ft but will not fit a 4 inch stile?
Several Grade 1 concealed vertical rod devices are wide stile and are not interchangeable with the 5547WDC-4ft, which fits stiles as narrow as 4 inches. The Adams Rite 8500 Series, Corbin Russwin ED5800, DORMA 9100 Series and BEST Precision 2801 Series are all wide stile devices. The BEST Precision 2701 is wide stile as well even though it is described for wood doors, so wood construction alone does not make it a drop in for a narrow stile wood leaf.
9) My doors are thicker than 1-3/4 inches. Which concealed vertical rod device covers that?
The Von Duprin 5547WDC-4ft is specified for 1-3/4 inch doors. For a thicker leaf, the DORMA 9100 Series is a Grade 1 heavy duty wide stile pushpad concealed vertical rod device listed for 1-3/4 inch to 2-1/4 inch doors, and the DORMA 9600BB covers the same 1-3/4 inch to 2-1/4 inch range in a narrow stile pushpad configuration.
10) Can the 5547WDC exit device be held open for deliveries or high traffic periods?
Yes, it has hex key dogging. Insert the hex key, depress the crossbar, and the latches stay retracted so the door pushes free as a passage door until you undog it. That only applies to the non-fire-rated version; if you order the -F fire rated model, dogging is not permitted on a labeled opening.
11) Why choose a concealed vertical rod device instead of a rim device on a pair of doors?
Concealed vertical rod latches at the head and the sill, so a pair of doors can be secured without a center mullion and nothing hangs on the face of the door but the crossbar. That matters on wood doors in historic or architectural work where the look is the point. The tradeoff: rods run inside the door, so the door has to be prepped for it and service means opening the door up. If the door cannot be prepped, the 55 Series also comes as a rim device with surface vertical rods (27) or with a mortise lock (75). For a mullion-and-rim solution on a pair, you give up the clean face but gain easier service.
12) Is there another crossbar style concealed vertical rod device that would look similar to the Von Duprin 55 Series?
The Corbin Russwin ED7800 is the closest match in the comparable range: a Grade 1 narrow stile crossbar concealed vertical rod device for 1-3/4 inch doors, exit only or accepting operator trim. Most other concealed vertical rod devices sold today are push pad, not crossbar, so if you are matching the look of existing crossbar hardware in a historic building those two are the pairing to consider.
13) I need the 5547WDC on a 42 inch wide door, not 48. Can it be cut down?
The 48 inch 55 Series device is field sizeable for single and double door applications, so it can be fit to narrower openings rather than ordered in an exact width. The 48 inch nominal size is the starting point for the range it covers.
14) Can the Von Duprin 5547WDC tie into access control or a door monitoring system?
Yes, two ways. The RX request to exit switch is an ordering option on the device itself and signals the access control or alarm panel when the crossbar is pushed. Separately, the 55 Series supports the E8875 option for access control, fire alarm and remote switching integration. If the device is going on a card reader opening or a monitored egress door, specify RX at order time rather than adding a surface switch later.
15) Are mounting screws included with the 5547WDC, or do I need to source fasteners?
A screw pack ships with the device, covering 1-1/4 inch and 2-1/4 inch thick metal and wood doors. The device itself is specified for 1-3/4 inch doors. What is not in the box is the trim, the cylinder for keyed functions like NL or NL-OP, and the top and bottom strikes for the frame and threshold, so budget those separately on the order.
16) Will the 1/2 inch latch throw on the 5547WDC work with my existing top and bottom strikes?
The 5547WDC latches with a 1/2 inch throw at the head and sill. That is a shorter throw than a rim device's deadlatch, so the top strike in the frame and the bottom strike or threshold prep have to be set for that engagement depth. If you are replacing a different brand of concealed vertical rod device, plan on new strikes rather than reusing what is in the frame, and check the existing rod prep in the door will take the Von Duprin rods.
17) What is a simpler exit only alternative if I do not need lever or cylinder trim on the Von Duprin 5547WDC-4ft?
If the outside face needs nothing but a pull or nothing at all, the Falcon 1690EO and Falcon 24-C are Grade 1 narrow stile concealed vertical rod devices in exit only function for 1-3/4 inch doors, both offered in a 36 inch size. The Falcon 1990EO is the same idea in a 44 inch length. The 5547WDC-4ft covers a 48 inch opening and can also be ordered EO, so the choice is about device length and whether you want the crossbar styling.
18) Is there a push pad narrow stile concealed vertical rod device instead of the crossbar on the Von Duprin 5547WDC-4ft?
Yes. The 5547WDC-4ft uses a crossbar actuator, which is often chosen for retro and historical work. If a facility standardizes on push pads, the DORMA 9600BB is a Grade 1 narrow stile pushpad concealed vertical rod device in a 36 inch size, non fire rated, listed for 1-3/4 inch to 2-1/4 inch doors. The CRL Jackson 1285 is also a push pad concealed vertical rod exit and covers narrow, medium or wide stile.
19) I need a dummy trim concealed vertical rod device for an inactive leaf. What are my options besides the Von Duprin 5547WDC-4ft?
The 5547WDC-4ft can be ordered with DT dummy trim. A dedicated alternative is the Falcon 1491DT, a Grade 1 narrow stile concealed vertical rod device in dummy function for 1-3/4 inch doors, supplied at 42 inches with a 9970 pull. The 5547WDC-4ft is a 48 inch device, so match the length to the leaf before choosing.
20) Is there a non-handed concealed vertical rod device I can stock instead of ordering the Von Duprin 5547WDC-4ft by hand?
The 5547WDC-4ft is field reversible for hand, though it is configured LHR or RHR at order. If you want a non-handed unit on the shelf, the BEST Precision 2601 is a non-handed narrow stile concealed vertical rod device in exit only, and the CRL Jackson 1085 is a 48 inch non-handed concealed vertical rod panic device in exit only for wide stile doors, matching the 48 inch length of the 5547WDC-4ft.
21) For a metal door with lever trim and hex dogging, what compares to the Von Duprin 5547WDC-4ft?
The Sargent MD8613F-LTRIM is a Grade 1 heavy duty concealed vertical rod exit device for metal doors at 36 by 84 inches with hex dogging and lever trim. The 5547WDC-4ft also uses hex key dogging and offers an L lever trim function with 06, 03, 07 and 17 lever styles, but it is a 48 inch narrow stile crossbar device intended for wood doors.
22) What finishes does the Von Duprin 5547WDC come in for matching existing hardware?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 643E aged bronze, and 693 black. For a building being standardized, 626 satin chrome and 613 oil rubbed bronze are the usual matches to existing lever and closer finishes; 643E and 605 tend to show up on historic and retro work, which is where the crossbar 55 Series is most often specified.
23) What is the KN knurled crossbar option on the Von Duprin 55 Series for?
Knurling is a tactile warning. The crossbar surface is textured so anyone reaching the door by touch knows they are entering a hazardous area, which is a requirement in mechanical rooms, electrical rooms and similar spaces in many facilities. Order KN as the crossbar option. The other two choices are the standard crossbar and RCB, a reinforced crossbar for abuse-prone or high traffic openings.
