    Von Duprin 33AEO 4 US26D – Frequently Asked Questions

    1) Is the Von Duprin 33A fire rated?
    The 33A-4ft as configured is not a fire rated device, so it cannot go on a fire door assembly. If the opening is a labeled fire door, look at a fire rated rim device instead: the Adams Rite 3700 Series narrow stile is fire rated, and the Arrow FS1250 is a fire rated 32 inch rim device. Because it is not fire rated, this one can be dogged down for hold-open, which a fire rated device never allows.
    2) Do I have to specify a hand for the Von Duprin 33A?
    No handing to call out. The 33A rim device is non-handed and goes on a left or right hand opening as shipped, which is why it works for a facility standardizing one part number across mixed openings.
    3) Which strike do I order with the Von Duprin 33A for a hollow metal frame?
    Strike choice is part of the order. The default is the 1439 roller strike, which suits aluminum storefront work; for hollow metal and wood door frames, select the 299 strike instead. The latchbolt throws 3/4 inch, so whichever strike you pick has to be set to catch that throw at the frame.
    4) How do I get outside access with a Von Duprin 33A, or does it lock behind you?
    On its own the device is exit only. Outside trim is a separate choice on the order: lever function (L), lever with blank escutcheon (L-BE), night latch (NL), night latch with optional pull (NL-OP), thumbturn (T), thumbturn and unlocks (TL), dummy trim (DT), and the escutcheon variants. If you pick an L trim you also pick the lever design, from 01, 02, 03, 05, 06, 07, 17 or 18.
    5) Does the Von Duprin 33A meet the 5 pound ADA operating force requirement?
    Only in the AX configuration, which you have to select when ordering. AX is certified to the 5 pound force requirements of 2010 ADA Chapters 404.2.7 and 30934 and 2013 California Building Code Chapter 11B-309.4. The standard build is not sold against that certification, so if the opening is on an accessible route, order it AX.
    6) Should I use a rim exit device or a vertical rod device on a pair of doors?
    A rim device latches into a strike on the frame or on a mullion, so on a pair you need a removable mullion between the leaves. If you cannot use a mullion, the same 33A/35A platform is ordered as a vertical rod instead: 27 for surface mounted vertical rod, 47 for concealed rod with 5/8 inch bottom bolt, 48 for concealed rod with 1-1/2 inch bottom bolt, 49 for concealed vertical cable, and 50WDC for wood door concealed cable. Vertical rod latches top and bottom, so it secures a pair with no mullion in the way of traffic.
    7) What is the closest narrow stile Grade 1 rim exit device to the Von Duprin 33A if the opening is a wood door?
    The Von Duprin 33A is not wood door compatible, so on a wood door the Adams Rite 8700 Series narrow stile rim exit device is the direct narrow stile alternative - it is Grade 1, narrow stile, and wood door compatible. The Adams Rite 3700 Series is the same narrow stile Grade 1 platform in a fire rated version and is also wood door compatible, so it covers a wood opening that needs a fire label. Both use Adams Rite starwheel interlocking rather than the 33A grooved case push pad mechanism.
    8) Which other manufacturers make a Grade 1 narrow stile rim exit device that competes with the Von Duprin 33A?
    The Von Duprin 33A is a Grade 1 narrow stile rim device. Cross brand peers on the same narrow stile Grade 1 footing include the Corbin Russwin ED4200, a 36 inch narrow stile rim device for 1-3/4 inch doors that is exit only or accepts trim; the Falcon 1590EO and 1790EO, both 42 inch narrow stile exit only devices for 1-3/4 inch doors; the Falcon 19-R, a 36 inch narrow stile exit only device; the Detex 40 Advantex, an extra heavy duty narrow stile device; and the Sargent 8504, a narrow design rim device in night latch function. The Adams Rite 8800 Series is narrow stile Grade 1 and covers a 1-3/4 inch to 2-1/4 inch door thickness range, where the 33A is specified for 1-3/4 inch.
    9) What matches the Von Duprin 33A when the door is thicker than 1-3/4 inches?
    The Von Duprin 33A is specified for 1-3/4 inch doors and ships with 1-3/4 inch and 2-1/4 inch wood/metal door fasteners with SNB included. Where a device is needed with a published range past 1-3/4 inch, the Adams Rite 8800 Series is a narrow stile Grade 1 device covering 1-3/4 inch to 2-1/4 inch, the Dormakaba 9300A covers the same 1-3/4 inch to 2-1/4 inch range in a 48 inch wide stile exit only device, and the SDC S6136 covers 1-3/4 inch to 2 inch on a 4 inch wide stile.
    10) The 33A is not fire rated - what fire rated rim exit device can go on a labeled opening instead?
    The Von Duprin 33A carries a Fire Rating of No, so a labeled opening needs a device listed for it. The Adams Rite 3700 Series is fire rated, Grade 1, and narrow stile, which keeps the narrow stile geometry. On non narrow stile labeled openings, the Dexter ED1000 Series fire rated rim device is Grade 1, the Marks USA M9900F is available in both 36 inch and 48 inch fire rated exit only versions, and the Orca OED85 Series is a 36 inch fire rated rim device. The Arrow FS1250 is a fire rated 32 inch rim device for 1-3/4 inch doors.
    11) Can a wide stile rim exit device be used in place of the Von Duprin 33A?
    Only if the door stile allows it. The Von Duprin 33A is built for narrow stile doors, which is why it is specified on aluminum storefront where stile width is limited. Wide stile Grade 1 rim devices such as the Corbin Russwin ED5200, the Dormakaba DORMA 8300 Series, the TownSteel ED1100, the BEST Precision 2101, and the Detex 10 Advantex are dimensionally different products and need the wider stile to mount. The SDC S6136 is explicitly built around a 4 inch wide stile. If the opening is a storefront door, these are not interchangeable with the 33A.
    12) Is an electrified exit bar like the Securitron EMB or SDC PSB560 a substitute for the Von Duprin 33A?
    They are different devices. The Von Duprin 33A is a mechanical Grade 1 rim exit device with a 3/4 inch latch throw that latches into a strike, and it can be ordered with electric or quiet electric latch retraction and request to exit or latchbolt monitor switches while keeping that mechanical latch. The Securitron EMB is an electromechanical exit bar for 2-1/4 inch doors, and the SDC MSB550 is a mechanical switch bar that releases an electromagnetic lock rather than throwing its own latch. The SDC SureExit PSB560 is a pressure sense bar. If the opening relies on a maglock or an electric release for security, those bars fit; if the door must latch on its own, the 33A does something they do not.
    13) What dogging options come on the Von Duprin 33A exit device?
    Hex key dogging is standard, letting maintenance hold the latch retracted during business hours with an allen wrench. You can order CD cylinder dogging if you want it keyed instead of hex, CDSI or HDSI if you want a visual indicator showing dogged or secure, or LD less dogging where the code or the facility does not permit hold-open.
    14) Can I get delayed egress on a Von Duprin 33A for a stairwell or a retail exit?
    Yes, through the CX CHEXIT option, which gives a 15 second delay with a nuisance alarm and meets NFPA and IBC requirements for delayed egress. Existing 33A devices in the field can be brought up to it with the Chexit PCB kit rather than replacing the device.
    15) Can I add cylinder dogging or an indicator to a Von Duprin 33A I already have installed?
    Yes. The 33A supports field retrofit rather than replacement: the 107813 cylinder dogging kit converts CD and SS applications, and CDSI/HDSI dogging indicator kits, QEL quiet electric latch retraction, and RX and LX switch kits are all offered as retrofits to keep an installed device current with access control changes.
    16) Which rim device is closest to the Von Duprin 33A for hex key dogging on a narrow stile door?
    The Von Duprin 33A ships with hex key dogging as its standard dogging configuration on a narrow stile Grade 1 device. The Stanley Security QED200 Series is a Grade 1 heavy duty narrow stile rim exit device with hex key dogging, and the Dormakaba QED200 is the same series in a 36 inch narrow device with a 7 ft rod. The Design Hardware 1000R is a 33 inch heavy duty rim device with hex key dogging, and the 2000R is the standard duty wide stile counterpart. Note the 33A can also be ordered with cylinder dogging or with dogging indicators rather than hex key.
    17) Is a crossbar panic device the same thing as the Von Duprin 33A push pad?
    No. The Von Duprin 33A is a push pad style device with a 3-13/16 inch projection and a grooved mechanism case. Crossbar devices are a different actuator and a different look: the CRL Jackson 1095 Series is a 48 inch crossbar rim panic device in wide stile, exit only, and the Corbin Russwin ED3200 is a 48 inch Grade 1 crossbar rim device. The CRL Jackson 1095P is the paddle version and the 1295 Series is a non-handed push pad wide stile device for 1-3/4 inch doors. If a facility is standardizing on push pads, a crossbar device will not match the existing doors even at the same width.
    18) Is there a simpler exit only device instead of the Von Duprin 33A when no outside trim is needed?
    Yes. The 33A is ordered with trim functions ranging from exit only through lever, night latch, and thumbturn, so it can be specified as exit only. If the opening needs nothing but egress, a dedicated exit only device is a simpler order: the Dexter ED1000 Series is a Grade 1 rim device offered in 3FT and 4FT exit only sizes, the Marks USA M9900 is a 36 inch exit only rim device, and the Orca OED55 is a 36 inch exit only rim device. The BEST 2401 Series is a narrow stile exit only, non-handed rim device, which keeps both the narrow stile fit and the non-handed behavior of the 33A.
    19) What is the difference between the Von Duprin 33A and the Cal-Royal A9820 for a 48 inch opening?
    Both cover a 48 inch device size - the Von Duprin 33A is a 48 inch push pad device certified Grade 1, and the Cal-Royal A9820 is a 48 inch exit only rim device carrying a Grade 2 rating, as does the Cal-Royal 5500 48 inch push bar device. The 33A is non-handed and includes hex key dogging as standard, and it is specified for 1-3/4 inch doors. For a 48 inch wide stile opening on a Grade 1 platform, the Corbin Russwin ED3200 is a 48 inch crossbar rim device and the Dormakaba 9300A is a 48 inch wide stile exit only device covering 1-3/4 inch to 2-1/4 inch doors.
    20) Which narrow stile rim exit devices are non-handed like the Von Duprin 33A?
    The Von Duprin 33A is non-handed except when the SS signal switch option is used, so one part number covers both hands on single doors and on double doors with a mullion. Among peers, the BEST 2401 Series is a narrow stile non-handed exit only rim device and the BEST Precision 5101 Series is a non-handed universal design rim device. On the wide stile side, the CRL Jackson 1295 Series is non-handed for 1-3/4 inch doors, and the Sargent 2828 and 3828 are reversible Grade 1 devices for 48 inch minimum door width. Non-handed and reversible both remove the handing decision, but reversible devices are set at install rather than shipping ready for either hand.
    21) What should I order instead of the Von Duprin 33A if the opening is a concealed vertical rod door rather than a rim application?
    The Von Duprin 33A is a rim device, and the 33A platform itself is available in surface vertical rod, concealed vertical rod, and concealed vertical cable configurations. If the specification calls for another brand on a concealed vertical rod opening, the Hager 4601 Series is a 36 inch Grade 1 concealed vertical rod narrow stile exit device, which keeps the narrow stile fit; the Hager 4501 Series is the 36 inch Grade 1 concealed vertical rod device with a wide stile pushpad. Hager's 4701 Series is a 36 inch standard duty rim device with Grade 1 BHMA certification if the opening turns out to be rim after all.
    22) Which narrow stile rim device should I use if I need a night latch function rather than the Von Duprin 33A configuration I have?
    The Von Duprin 33A is ordered in night latch and night latch with optional pull trim functions alongside lever, thumbturn, and exit only, so the function is a trim selection on the same device. If the job calls for a different brand in that function, the Sargent 8504 is a narrow design rim exit device in night latch function, Grade 1. The Detex V4003A/03AN is a Grade 1 wide stile rim device with night latch trim, so it only suits an opening with the stile width for it.
    23) What are the Grade 2 alternatives to the Von Duprin 33A and what changes?
    The Von Duprin 33A is certified to ANSI/BHMA A156.3 2014 Grade 1. The Cal-Royal 5000 is a 36 inch heavy duty touch bar rim device and the Cal-Royal 5500 a 48 inch heavy duty push bar rim device, both Grade 2. The Cal-Royal A9800 and A9820 are also carried at Grade 2. For a facility standardizing on Grade 1 for institutional traffic, those are a different certification tier, and where a spec sheet or code review calls out Grade 1 they will not satisfy it.
    24) Which exit device gives the heaviest duty rating for a high traffic narrow stile opening compared to the Von Duprin 33A?
    The Von Duprin 33A is a Grade 1 commercial device built for school, hospital, and government traffic. Among narrow stile peers, the Detex 40 Advantex Series is rated extra heavy duty and Grade 1, while the Stanley QED200 and Dormakaba QED200 are rated heavy duty and Grade 1. On the wide stile side the Detex 10 Advantex is extra heavy duty Grade 1. Duty level and ANSI grade are separate marks - all of these hold Grade 1 - so a duty rating is an additional description of the chassis, not a higher certification.
    25) Is the Adams Rite EX88 an alternative to the Von Duprin 33A on an aluminum storefront door?
    It is a narrow stile option for the same kind of opening. The Adams Rite EX88 is a Grade 1 interlocking rim exit device with narrow stile design, so it suits the aluminum storefront and narrow stile doors the 33A is built for. The difference is the mechanism: the EX88 is an interlocking rim device, while the 33A is a grooved case push pad device with a 3/4 inch latch throw and hex key dogging. Where an existing storefront already runs Adams Rite interlocking hardware, the EX88 or the 8800 Series stays in that family.
    26) What is a dummy exit device and can it replace the Von Duprin 33A on an inactive leaf?
    A dummy device gives the matching push bar appearance without a working latch. The Von Duprin 33A is ordered with a DT dummy trim and an L-DT lever dummy trim function, so the 33A family covers that on the same device. From other brands, the Detex Advantex 00 Series is a super heavy duty dummy exit device in wide stile design, Grade 1, and the Sargent 12-8810-LTRIM is a fire rated wide stile device in dummy function with RX and motorized latch retraction. A dummy will not latch or secure the leaf, so it belongs only where the active leaf carries the egress hardware.
    27) What finishes does the Von Duprin 33A come in for matching existing doors?
    Ten finishes across the 33A: 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. On storefront work 628 and 710 are the ones that line up with common aluminum door finishes.
    28) Do the Arrow rim exit devices cross to the Von Duprin 33A?
    Partly, depending on the stile. The Arrow 4800 Series is a 36 inch narrow stile rim device, exit only, for 1-3/4 inch doors, which matches the 33A on stile type and door thickness. The Arrow 3880 Series is a 30 inch wide stile pushpad exit only device for 1-3/4 inch doors, so it needs the wider stile. The Arrow ED910 is a 36 inch rim device for 1-3/4 inch doors. None of these are wood door compatible, the same as the 33A.
