Von Duprin 35A-3-626 – Frequently Asked Questions

1) Will the Von Duprin 35A-EO fit a narrow stile aluminum storefront door?
That is exactly what the 35A-EO is built for. It is a narrow stile rim device, so the mechanism case fits the slim vertical stile of an aluminum storefront leaf instead of needing the 4 inch or wider face a wide stile device wants. The case measures 8-3/16 x 1-9/16 x 2-13/32 inches with a 3-13/16 inch projection off the door face, which is what you check against your stile and against anything in the door swing path. Door thickness is 1-3/4 inches. It is not for wood doors.
2) Do I have to order the Von Duprin 35A left hand or right hand?
No handing to specify. The 35A-EO is non-handed, so one part number covers both a left hand and a right hand opening, and you can stock a single device for a building with doors swinging both ways. What you do have to pick is length: the 3'0 device covers doors from 2'4" to 3'0" and the 4'0 device covers 3'1" to 4'0", plus finish and whether you want the fire rated or the non-fire-rated version.
3) Can I dog down a fire rated Von Duprin 35A so the door stays push-open during business hours?
Not on the fire rated version. Dogging and fire rating are an either/or choice on the 35A: order it non-fire-rated and you get the hex key dogging feature, which lets you hold the pushpad depressed and the latch retracted for free traffic. Order the fire rated version and there is no dogging, because a fire door has to relatch every time it closes. If you need a door that latches for fire but still stays open for traffic, you need electric latch retraction (the QEL option) tied to your access control, not mechanical dogging.
4) Is the Von Duprin 35A-EO fire rated, and what standards does it carry?
Fire rating is an option, identified by the -F suffix. The base 35A-EO is certified to ANSI/BHMA A156.3 2014 Grade 1, ANSI/UL 305 and CAN/ULC-S132 as panic hardware. Order the fire rated configuration and it additionally meets ANSI/UL 10C and CAN/ULC-S104. For a stair door, corridor cross door, or anything on a rated wall assembly, take the fire rated variant; for an exterior exit or a non-rated opening where you want to dog the door open, the standard version is the one.
5) What does Exit Only mean on the 35A-EO, and can I add a lever or pull on the outside later?
Exit Only means the device ships with no outside trim. Push the pad from inside and you are out; from the outside there is no lever, no pull, no key cylinder, so the door is not enterable through the device. That is the right spec for an exterior emergency exit, a stair discharge, or any door where nobody comes back in. If you need key or lever entry from the outside, the EO is the wrong configuration to start from, and you should order the 35A in a trim-accepting function rather than trying to add trim to an EO device.
6) Will the Von Duprin 35A latch into the strike that is already on my frame?
The 35A throws a 3/4 inch latchbolt into a surface-mounted rim strike on the frame stop. Because it is a rim device, the latching happens at the strike only, not at the head and sill, so the number to check is your existing strike's lip and its position against a 3/4 inch throw. Mounting centerline for the device is 39-13/16 inches off the finished floor, so measure your current strike against that height before you assume the old one carries over.
7) I have a pair of doors with no center mullion. Can I use a rim exit device like the 35A?
Not on its own. A rim device latches into a strike on the frame, and a pair with no mullion has no frame at the meeting stile to strike into. Two choices: add a removable mullion and run rim devices on both leaves, or go to a vertical rod device that latches at the head and the threshold instead. The 35 Series covers that second path with surface vertical rod (27), concealed vertical rod with a 5/8 inch or 1-1/2 inch bottom bolt (47/48), and concealed vertical cable (49) device types.
8) What is the narrow stile alternative to the Von Duprin 35A if I need one that works on a wood door?
The 35A is metal and aluminum door only, so a wood leaf rules it out. Two Adams Rite narrow stile rim devices are listed as wood door compatible: the 3700 Series with starwheel interlocking, which is fire rated and Grade 1, and the non-fire-rated 8700 Series, also Grade 1 with starwheel interlocking. Match the fire rating to your opening, since only the 3700 carries one.
9) My door is thicker than 1-3/4 inches. What rim exit device should I use instead of the Von Duprin 35A?
The 35A is a single-thickness device at 1-3/4 inches, so a thicker leaf takes something else. The Adams Rite 8800 Series narrow stile rim device covers 1-3/4 to 2-1/4 inches, and the DORMA 9300 Series covers the same 1-3/4 to 2-1/4 range in a wide stile Grade 1 heavy duty build if your stile allows it. The SDC S6136 Spectra covers 1-3/4 to 2 inches on a 4 inch wide stile.
10) What are the alternatives to the Von Duprin 35A-EO for a fire-rated opening?
The 35A-EO offers a fire-rated configuration under the -F suffix, and fire-rated devices come with no dogging. Cross-brand fire-rated rim exit devices include the Dexter ED1000-R-F-EO, a Grade 1 fire rated rim device; the Marks USA M9900F in 36 inch and 48 inch, exit only with a panic protector end cap; the Orca OED85 Series 36 inch fire rated rim device, exit only; and the Arrow FS1250 fire rated 32 inch rim device for 1-3/4 inch doors. Of these, the Adams Rite 3700 Series is the one that is also narrow stile like the 35A.
11) My door has a wide stile - what should I order instead of the Von Duprin 35A-EO?
The 35A-EO is built for narrow stile doors, so on a 4 inch or wider stile the Corbin Russwin ED5200 is the direct step across: Grade 1, wide stile, rim, 36 inch, for 1-3/4 inch doors, exit only or accepting trim. Other Grade 1 wide stile rim options are the Corbin Russwin ED2200 36 inch exit only, the Detex Advantex 10 Series 36 inch extra heavy duty, the TownSteel ED1100 36 inch heavy duty, and the DORMA 9300 Series 48 inch exit only, which takes doors 1-3/4 inch to 2-1/4 inch thick.
12) Which narrow stile exit device should I use if I need outside key access rather than exit only?
The Von Duprin 35A-EO is an exit only device with no outside trim. For a narrow stile opening that needs outside key entry, the Sargent 8504 is a Grade 1 narrow stile rim exit device in a night latch function. The Corbin Russwin ED4200 is a Grade 1 narrow stile rim device offered exit only or accepting trim, so it can be ordered with outside trim on the same opening.
13) I need a 48 inch narrow stile rim device - what else covers a 4 foot door besides the Von Duprin 35A?
The 35A-EO covers 36 inch and 48 inch doors, with the 4'0 size fitting 3'1 to 4'0 leaves. For 48 inch openings from other makers, the Dexter ED1000-R-EO-4FT is a Grade 1 rim device in a 4 foot size, the Marks USA M9900F-48 is a fire rated 48 inch rim device exit only, and the DORMA 9300 Series is a Grade 1 wide stile 48 inch device exit only. The Sargent 2828 and 3828 are Grade 1 reversible rim devices for 48 inch doors, both wide stile.
14) Do the SDC exit bars work as a replacement for a Von Duprin 35A rim exit device?
They solve a different problem. The 35A-EO is a mechanical Grade 1 rim exit device with a latch and a 3/4 inch throw. The SDC MSB550 Series 36 inch is a mechanical switch bar that releases an electromagnetic lock, and the SDC PSB560 SureExit 36 inch is a pressure sense bar with tri-failsafe technology; both fit narrow or wide stile doors but signal a lock release rather than throwing a latch of their own. The SDC S6136 Spectra is an electrified architectural rim exit device, but it is wide stile with a 4 inch stile requirement and takes doors 1-3/4 inch to 2 inch.
15) What mounting hardware comes with the Von Duprin 35A, and do I need anything else to hang it?
Fasteners are in the box: 1-3/4 inch and 2-1/4 inch wood/metal door fasteners plus SNB (sex nut and bolt) hardware for through-bolting. What is not in the box is the rim strike for the frame side, which you specify separately along with any trim or accessory. On a hollow metal or aluminum door the SNB set is what you want for a high-traffic opening, because through-bolting resists the pull-off that screws into a thin skin will not.
16) Can I get a delayed egress or request-to-exit signal on a Von Duprin 35A?
Both, as ordered options on the 35 Series. CX (CHEXIT) delayed egress gives a 15-second delay with a local alarm and meets NFPA and IBC requirements, which is the usual answer for a hospital behavioral unit or a retail loss-prevention door. RX and LX provide request-to-exit and latchbolt monitoring signals back to your access control or alarm panel. QEL is the quiet electric latch retraction option, CDSI/HDSI are the security dogging indicators, and AX is the ADA-compliant operation at 5 lb operating force per ADA 2010 and CBC 2013. Each of these is a suffix specified at order time, not a field add-on.
17) What are the closest Grade 1 narrow stile rim exit device alternatives to the Von Duprin 35A-EO?
Several land in the same spot. The Falcon 19-R Series is Grade 1 narrow stile, exit only, for 1-3/4 inch doors, as is the Falcon 1590EO in a 42 inch device. The Corbin Russwin ED4200 is Grade 1 narrow stile for 1-3/4 inch doors and is configured exit only or to accept trim, so it is the one to look at if you might want outside trim later. Detex 40 Advantex is Grade 1 narrow stile in an extra heavy duty build. The BEST 2401 Series is narrow stile exit only and non-handed, which matches the 35A's non-handed behaviour.
18) Is a Grade 1 exit device like the Von Duprin 35A overkill for a small retail back door, or should I drop to Grade 2?
Grade 1 is the top ANSI/BHMA durability tier and the 35A is certified to A156.3 2014 Grade 1, which is what a school corridor, a hospital, or a government building spec will call for. On a low-traffic back door where the spec does not name a grade, Cal-Royal's Grade 2 chassis devices are the step down: the 5000 at 36 inches with a touch bar and the 5500 at 48 inches with a push bar, both heavy duty. If the door is on an egress path in an institutional facility, stay at Grade 1.
19) Which other exit devices come with hex key dogging like the Von Duprin 35A?
The 35A-EO ships with hex key dogging on non-fire-rated builds. The Design Hardware 1000R in 33 inch is a heavy duty rim device with hex key dogging, and the 2000R in 33 inch is the standard duty wide stile version with hex key dogging. The Stanley Security QED200 Series is a Grade 1 heavy duty narrow stile rim exit device with hex-key dogging, and Dormakaba lists the same QED200 Series as a Grade 1 heavy duty narrow device in a 36 inch size with a 7 foot rod.
20) Is a crossbar exit device an equivalent to the Von Duprin 35A-EO?
Not in appearance or operation. The 35A-EO is a push pad style device on a narrow stile door. Crossbar devices include the Corbin Russwin ED3200, a Grade 1 wide stile 48 inch crossbar rim device for 1-3/4 inch doors, and the CRL Jackson 1095 Series 48 inch crossbar rim panic device, wide stile and exit only. If the goal is a push pad look on a wide stile leaf, the CRL Jackson 1295 Series is a non-handed push pad rim panic device for 1-3/4 inch doors, and CRL also offers the 1095P paddle version.
21) Are there simpler narrow stile rim exit device options than the Von Duprin 35A-EO?
Yes, if you do not need the electrified and delayed egress options the 35A supports. The Marks USA M8800 is a 36 inch narrow stile rim device, exit only, with panic protector end caps. The Arrow 4800 Series in 36 inch is a narrow stile rim exit device, exit only, for 1-3/4 inch doors. The BEST Precision 2401 Series is a narrow stile rim exit device, exit only and non-handed, matching the 35A-EO's non-handed operation.
22) What is the difference between the Von Duprin 35A-EO and the Falcon 1590EO or 1790EO?
All three are Grade 1 narrow stile rim exit devices in an exit only function for 1-3/4 inch doors and none are wood door compatible. The Falcon 1590EO and 1790EO are listed in a 42 inch size, while the Von Duprin 35A-EO comes in 36 inch and 48 inch, so the Falcons sit between the two Von Duprin sizes for a leaf around 3'6.
23) If the opening needs vertical rod instead of rim latching, what replaces the Von Duprin 35A-EO?
The 35A-EO is a rim device that latches into a strike on the frame. Where the opening calls for a concealed vertical rod, the Hager 4601 Series 36 inch is a Grade 1 concealed vertical rod narrow stile exit device, and the Hager 4501 Series 36 inch is the Grade 1 concealed vertical rod version with a wide stile pushpad.
24) Does the Sargent 12-8810-LTRIM work in place of a Von Duprin 35A-EO?
No, and the function is the reason. The Sargent 12-8810-LTRIM is a fire rated Grade 1 wide stile rim exit device in a dummy function with RX and MELR, so it does not latch on its own. The Detex Advantex 00 Series is likewise a Grade 1 wide stile dummy exit device. The Von Duprin 35A-EO is an operating Grade 1 exit only device with a 3/4 inch latch throw, so a dummy device is only the right pick on an inactive leaf.
25) What finishes does the Von Duprin 35A come in for matching the rest of my building's hardware?
Ten finishes, and every one of them is available in both the fire rated and non-fire-rated build and in both lengths: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 628 aluminum, 643E aged bronze, 710 dark bronze anodized, and 711 flat black. For a storefront match, 628 aluminum and 710 dark bronze anodized are the two that align with standard anodized frame finishes; 626 satin chrome is the common institutional choice.
26) Can I convert an existing Von Duprin 35 Series device to vertical rod or cable instead of replacing the whole opening?
The 35 Series is offered with retrofit kits for upgrading existing installations, and the family spans rim (no suffix), surface vertical rod (27), concealed vertical rod with a 5/8 inch or 1-1/2 inch bottom bolt (47 and 48), concealed vertical cable (49), and a wood door concealed vertical cable version (50WDC). That last one matters if you have a mixed building: the rim 35A itself is not for wood doors, but the 50WDC cable configuration addresses wood leaves.
