Von Duprin 78EO-F 3 626 – Frequently Asked Questions

1) Will the Von Duprin 78F-3ft fit a 36 inch wide door, and can it be cut down for a narrower opening?
The 78F-3ft is the 36 inch (3 ft) size of the Von Duprin 78 Series rim device, and the body is field sizeable, so it can be trimmed on site for a narrower door leaf. It is a wide stile pushpad device, which means the door needs a wide stile to give the chassis a mounting surface. Push pad style, with a 3-13/16 inch projection off the door face to allow for in the corridor clearance.
2) Can I put the Von Duprin 78F on a wood door?
No. The 78F is listed as not wood door compatible; it is specified for metal doors at 1-3/4 inch thickness. The screw pack in the box covers 1-3/4 inch and 2-1/4 inch metal or wood doors, and the optional 425 SNB sex bolt set handles other fastener needs, but the device itself is a metal door application. If you have a fire rated wood door, look at the Adams Rite 3700 Series narrow stile fire rated rim device, which is listed as wood door compatible.
3) Is the Von Duprin 78F approved for a fire rated door opening?
Yes. The 78F is a fire rated device, certified to ANSI/UL 10C and CAN/ULC-S104, and built to ANSI/BHMA A156.3-2014 Grade 1. That combination is what a fire rated assembly needs. Note that fire rated exit devices cannot be mechanically held retracted, so the dogging option matters on a fire door.
4) What strike do I order with the 78 Series rim device for a pair of doors?
Two strike choices. The 299 strike is the one for hollow metal and wood door frames on a single opening. For a double door application, order the 499F strike. The device latches with a 3/4 inch throw, so the strike has to be set to pick that up; on a pair, the 499F mounts to the inactive leaf or mullion rather than the frame stop.
5) What are the dogging options on the Von Duprin 78F and which one do I need?
Three ways to go. Standard is hex key dogging, where a hex wrench holds the pad down for free push-pull traffic. CD gives you cylinder dogging so the pad is dogged with a key instead of a wrench. LD is less dogging, no hold-open at all. On a fire rated opening you normally specify LD or an electric latch retraction option, because a fire door cannot be held mechanically latched back.
6) Can I get the Von Duprin 78 Series with electric latch retraction or a request to exit switch?
Yes on both. The 70 Series platform supports QEL quiet electric latch retraction, with HD-QEL adding hex dogging on panic-only devices, and QELX / HD-QELX for AX accessible devices. On the monitoring side you can specify RX request to exit, LX latchbolt monitor, LX-RX combination, RX2 double switch, WP-RX waterproof, or the ALK alarm exit kits in less-switch, RX, and LX/RX versions. That covers tying the opening into an access control or alarm system.
7) Which trim function do I pick for a door that needs outside key access but stays locked?
Night latch is the one for that. NL gives a key-retracted latch with a pull, NL-OP adds the optional pull, and L-NL pairs a lever with night latch operation. If the door never needs outside entry, EO exit only is the device alone. Other choices are L lever, L-BE lever with blank escutcheon, L-DT lever with dummy trim, and DT dummy trim. For any L function you also pick the lever design: 06 is default, with 01, 02, 03, 05, 07, 12, 16, 17 and 18 also offered.
8) My door has a narrow aluminum stile. Can I use the Von Duprin 78F?
No, the 78F is a wide stile device and needs the stile width to carry the chassis and push pad. For narrow stile aluminum storefront, go to a narrow stile rim device: the Adams Rite 8800 Series covers 1-3/4 to 2-1/4 inch doors, the Corbin Russwin ED4200 is a Grade 1 narrow stile at 1-3/4 inch, and the Falcon 19-R is a Grade 1 narrow stile exit only at 1-3/4 inch. If the narrow stile opening is also fire rated, the Adams Rite 3700 Series is the fire rated narrow stile choice.
9) What is the closest fire rated 36 inch rim exit device to the Von Duprin 78F-3ft from another manufacturer?
For a fire rated 36 inch rim device on a hollow metal opening, the closest peers are the Marks USA M9900F-36, a fire rated 36 inch rim exit device in exit only function, and the Orca Hardware OED85, a 36 inch fire rated rim device also supplied exit only. Both are fire rated like the 78F-3ft, which is Grade 1 and 36 inches. The difference to plan around: the Von Duprin 78F-3ft can be configured in EO, NL, L, L-NL, L-BE, L-DT, NL-OP or DT trim function, while those two peers are listed exit only, so if the opening needs outside lever or night latch entry the 78F-3ft covers it directly.
10) Which rim exit devices are Grade 1 and fire rated but should not be used in place of the 78F on a wide stile door?
The Adams Rite 3700 Series 30 inch is fire rated and Grade 1, but it is a narrow stile device, so it is not a swap for the 78F-3ft, which is built for wide stile doors. The same applies in reverse to the Adams Rite 8700 and 8800 narrow stile rim devices, which are Grade 1 but not fire rated. Match the stile before the grade: a narrow stile chassis has a different mounting footprint on a wide stile leaf.
11) What height should the 78 Series exit device be mounted at?
Von Duprin lists the device centerline at 39-13/16 inches from finished floor for the 78 Series. Use that number when you lay out the door prep and the strike, and match it across a bank of doors so the push pads line up.
12) What is the difference between the rim 78F and the vertical rod versions of the Von Duprin 78?
The rim device (no suffix) latches into a strike at the frame or mullion, which is the simplest install on a single door. For a pair with no mullion, you need a vertical rod device: 27/SVR mounts the rods on the door face, and 47/CVR runs them inside the door for a cleaner look and less exposed hardware. All three share the same 78 Series body and wide stile push pad.
13) What is the AX option on the Von Duprin 78 Series?
AX is the accessible device option, ordered yes or no. If you specify AX, the matching electric latch retraction versions are QELX and HD-QELX rather than the standard QEL and HD-QEL, so keep those two selections consistent on the order.
14) What is a comparable fire rated wide stile rim exit device if the Von Duprin 78F is not right for my job?
Among fire rated rim devices, the Sargent 12-8810 is a Grade 1 wide stile fire rated rim device with RX and motorized latch retraction built in. The Marks USA M9900F comes in 36 and 48 inch exit only versions, and the Dexter ED1000 Series has a Grade 1 fire rated rim model. For a narrow stile fire rated opening instead, the Adams Rite 3700 Series and the Arrow FS1250 (32 inch) are the fire rated options. Note none of those are stated as wide stile plus the full 78 Series electrification menu, so check the function you actually need.
15) If I do not need a fire rating, is there a cheaper Grade 1 wide stile rim device than the Von Duprin 78F?
Yes, several non-rated Grade 1 wide stile rim devices are made for non-fire openings: the Corbin Russwin ED5200 at 36 inches for 1-3/4 inch doors, the Corbin Russwin ED2200 exit only 36 inch, the TownSteel ED1100 36 inch heavy duty, and the DORMA 8300 Series. All are non fire rated, so only use them where the opening is not part of a rated assembly. The 78F is the one to keep when the door is rated.
16) Will the Von Duprin 78F latch reliably on a high traffic exterior door?
The 78F carries a 3/4 inch latch throw, which is the deep throw you want where doors get slammed or where a small amount of frame movement can otherwise leave a shallow latch riding the strike. Paired with the Grade 1 rating under ANSI/BHMA A156.3-2014, it is specified as a commercial device for warehouse, industrial, retail and multifamily traffic.
17) What is the difference between the Von Duprin 78F-3ft and a Grade 2 rim device like the Cal-Royal 5000?
The Cal-Royal 5000 is a 36 inch wide rim exit device with a Grade 2 chassis, heavy duty, and not fire rated. The Von Duprin 78F-3ft is ANSI/BHMA Grade 1 and fire rated. If the specification on the drawing calls for Grade 1 on a labeled opening, the Cal-Royal 5000 and the 48 inch Cal-Royal 5500, also Grade 2 and not fire rated, will not satisfy it.
18) Is there a fire rated Grade 1 rim device alternative to the 78F if we want a single part number without configuration options?
Yes. The Dexter ED1000-R-F-EO is a Grade 1 fire rated rim exit device supplied in a fixed exit only build, which is a simpler order than the 78F-3ft, where lever style, dogging type, switch, latch retraction and strike are each selected. The trade-off is that the 78F-3ft can be configured with cylinder dogging or less dogging in place of its standard hex key dogging, with RX, LX or alarm kit switches, and with QEL electric latch retraction, none of which the Dexter exit only device is listed to offer.
19) We need a 48 inch fire rated rim device for a wider leaf instead of the 36 inch 78F. What is available?
The Von Duprin 78F-3ft covers a 36 inch opening. For a wider leaf, the Marks USA M9900F-48 is a 48 inch fire rated rim panic device in exit only function with a panic protector end cap. Confirm the trim requirement first, since the M9900F-48 is exit only while the 78F-3ft can be built with lever or night latch trim.
20) Is an electrified exit bar like the SDC S6136 or Securitron EMB a substitute for a Von Duprin 78F with QEL?
They are different animals. The SDC S6136 is a 36 inch electrified architectural rim exit device on a 4 inch wide stile and is not fire rated, and the Securitron EMB is an electromechanical exit bar for 2-1/4 inch doors. The Von Duprin 78F-3ft is a fire rated Grade 1 mechanical rim device that fits 1-3/4 inch doors and supports QEL quiet electric latch retraction as an option. If the opening carries a fire label, the non-rated SDC device is not an equivalent.
21) Our building standard is push pad, not crossbar. Which comparable devices are crossbar and should be avoided?
The Von Duprin 78F-3ft is a push pad device. Crossbar style peers include the CRL Jackson 1095 Series 48 inch crossbar rim panic device and the Corbin Russwin ED3200, a Grade 1 48 inch crossbar rim device. Neither matches a push pad building standard, and both are listed as not fire rated, unlike the fire rated 78F-3ft.
22) We are standardizing on hex key dogging across a facility. Which other rim devices list hex key dogging?
The Von Duprin 78F-3ft ships standard with hex key dogging, with cylinder dogging and less dogging available instead. Peers that also list hex key dogging include the Design Hardware 1000R 33 inch heavy duty rim device, the Design Hardware 2000R 33 inch standard duty wide stile rim device, and the Stanley Security QED200 Series Grade 1 heavy duty narrow stile device. Note that both Design Hardware devices are not fire rated, so on a labeled assembly the 78F-3ft is the one that carries the fire rating.
23) What wide stile fire rated rim device offers a factory RX switch like the Von Duprin 78F does?
The Sargent 12-8810-LTRIM is a fire rated Grade 1 wide stile rim exit device supplied with RX and motorized electric latch retraction. The Von Duprin 78F-3ft is also fire rated, Grade 1 and wide stile, and can be ordered with RX, LX, LX-RX, RX2, WP-RX or alarm kit switching, plus QEL quiet electric latch retraction. Decide on the latch retraction type, since the Sargent peer is listed with MELR while the 78F platform uses QEL.
24) I need to match existing hardware finishes across a building. What finishes does the Von Duprin 78F come in?
Ten finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 619 satin nickel, 625 bright chrome, 626 satin chrome, 628 aluminum, 643E aged bronze, 710 dark bronze anodized, and 711 flat black. 626 satin chrome and 628 aluminum are the usual matches on commercial openings.
