    Von Duprin 3327AEO-F 4 US26D – Frequently Asked Questions

    1) Will the Von Duprin 3327AF fit a narrow stile aluminum storefront door?
    Yes. The 3327AF is a narrow stile device and fits stiles as narrow as 1-3/4 inches (44mm), which is why it goes on aluminum-framed storefront and other narrow stile commercial doors. Door thickness is 1-3/4 inches, the standard commercial thickness. If your stile is narrower than 1-3/4 inches, this device will not land on the door face.
    2) Can I use the Von Duprin 3327AF on a fire rated opening?
    Yes. The 3327AF is fire rated and listed under ANSI/UL 10C and CAN/ULC-S104 for fire rated panic exit hardware, and it is ANSI/BHMA A156.3 2014 Grade 1. One consequence of the fire listing: fire rated exit devices are supplied less dogging, so you cannot hold the latches retracted mechanically.
    3) Will a surface vertical rod exit device secure a pair of doors without a mullion?
    Yes. A surface vertical rod device like the 3327AF latches into a strike at the head and at the threshold rather than into the door edge, so a pair of doors can be secured with no center mullion. If you would rather keep a mullion and a simpler single latch point, a rim device is the other route, but then you are adding the mullion to the opening.
    4) How do I get this exit device to work with an access control system?
    Two separate choices. For monitoring, the switch options are RX request to exit, LX latchbolt monitor, LX-RX combination, RX2 double request to exit, WP-RX waterproof, ALK alarm kit less switch, RX-ALK, and LXRX-ALK. For remote unlocking, latch retraction options are EL electric, QEL quiet electric, or PN pneumatic. Getting power across the opening usually means an electric power transfer such as the Von Duprin EPT2.
    5) I need the exit device to meet the 5 lb ADA operating force. Can this one do it?
    Order it with the AX accessible device option. AX meets the 5 lb force requirement under 2010 ADA Chapters 404.2.7 and 30934 and the 2013 California Building Code Chapter 11B-309.4. It is a build option, not a field adjustment, so specify it at time of order.
    6) Will the 3327AF latch into the strikes already on my opening?
    Latch throw on the 3327A is 3/4 inch at both top and bottom, so the existing top and floor strikes have to be set for that throw and aligned to a surface vertical rod device. If you are replacing a different brand or a concealed rod device, plan on new top and bottom strikes and latch brackets rather than reusing the old prep.
    7) What is the closest fire rated surface vertical rod alternative to the Von Duprin 3327AF if I need a different brand?
    The Von Duprin 3327AF-4ft is a fire rated Grade 1 surface vertical rod device for narrow stile doors with a 1-3/4 inch door thickness. For a fire rated cross-brand equivalent, the Adams Rite 3100 Series 30 inch surface vertical rod device is also fire rated and Grade 1 with a 1-3/4 inch door thickness, though it is a wide stile device. The Arrow S1150 30 inch is fire rated and listed for narrow or wide stile applications at 1-3/4 inch doors, which keeps it closer to the narrow stile profile.
    8) My door is a wide stile hollow metal door on a rated opening - what should I use instead of the Von Duprin 3327AF?
    The Von Duprin 3327AF-4ft is built for narrow stile doors down to 1-3/4 inch stiles, so a wide stile leaf is better served by a wide stile device. Fire rated wide stile options include the Adams Rite 3100 Series 30 inch Grade 1 device, the Sargent 2727 Grade 1 reversible exit only device, and the TownSteel EF9727 36 inch by 84 inch Grade 1 heavy duty device, which is also listed as wood door compatible.
    9) Do I have to order a handed version of this Von Duprin vertical rod device?
    The device itself is non-handed, so one part number covers both single and double door installs. Handing is still specified on the order (RHR or LHR) because trim and options key off it, and the one exception called out is the SS signal switch option, which makes the device handed.
    10) Should I order the 3327AF less bottom rod?
    Less bottom rod is an option on the 3327AF, and it is what most people pick where the bottom rod and floor strike are a maintenance problem: dirty thresholds, snow and ice, carts and gurneys catching the rod, or where the floor strike is a trip hazard. With LBR you lose the bottom latching point, so the top latch is doing the work. Keep the bottom rod where the opening needs the two-point latching.
    11) What trim functions can I get with the Von Duprin 3327A vertical rod device?
    Ten trim functions are offered: EO exit only, L lever, L-BE lever with blank escutcheon, L-DT lever dummy trim, NL night latch, NL-OP night latch with optional pull, T thumbturn, T-BE thumbturn with blank escutcheon, TL thumbturn and unlocks, and TL-BE thumbturn and unlocks with blank escutcheon. If you pick an L function, you also choose the lever style: 06 is the default, with 01, 02, 03, 05, 07, 17 and 18 also available.
    12) What fasteners come with the Von Duprin 3327AF, or do I need to buy mounting hardware?
    Mounting hardware ships with the device: 1-3/4 inch and 2-1/4 inch wood and metal door fasteners plus SNB (sex nuts and bolts). That covers both hollow metal and wood door constructions without a separate fastener order. Strikes, trim, and any electrified accessories are separate.
    13) What is the difference between the Von Duprin 3327A and the 3527A?
    Case profile. The 3327A carries a grooved mechanism case; the 3527A is the smooth case version of the same 33A/35A Series device. Function, narrow stile fit, and Grade 1 fire rated performance are the same, so the choice is architectural appearance and matching what is already on the other openings in the building.
    14) I need a crossbar style device rather than a push pad - what is the alternative to the 3327AF?
    The Von Duprin 3327AF-4ft is a push pad style device. If the specification calls for a crossbar on a narrow stile door, the Corbin Russwin ED7400 is a Grade 1 narrow stile crossbar surface vertical rod device for 1-3/4 inch doors that accepts operator trim. It is not fire rated, so it suits non-rated openings only.
    15) Is there a lighter duty vertical rod exit device than the Von Duprin 3327AF for a non-rated interior door?
    The 3327AF-4ft is an ANSI/BHMA Grade 1 fire rated device. Where the opening is not rated and the traffic is lighter, the Dexter ED2000 Series is a Grade 2 surface vertical rod panic device and the TownSteel TS5100 Series 36 inch by 84 inch is a Grade 2 heavy duty wide stile device; neither is fire rated. The Design Hardware 2000V 33 inch is a standard duty surface vertical rod device, also without a fire rating.
    16) Does the Von Duprin 3327AF need to be handed the way a reversible competitor device does?
    The Von Duprin 3327AF-4ft surface vertical rod device is non-handed, so one device covers left and right hand reverse openings. Some comparable devices reach the same flexibility by being reversible in the field, such as the BEST Precision 5201 Series 36 inch and the Sargent 2727, both described as reversible surface vertical rod devices.
    17) How does the Von Duprin 3327AF compare with the Sargent 12-8710 for a rated door?
    The Von Duprin 3327AF-4ft is a Grade 1 fire rated narrow stile surface vertical rod device with a working push pad and a 3/4 inch latch throw. The Sargent 12-8710 is a Grade 1 wide stile surface vertical rod device with a dummy function, meaning it is non-operating trim rather than an active egress device. For an opening that must release for egress, the 3327AF-4ft is the operating device.
    18) Is there a less bottom rod alternative to the Von Duprin 3327AF?
    The Von Duprin 3327AF-4ft can be configured less bottom rod. Among comparable devices, the Orca Hardware OED56 Series 36 inch is supplied less bottom rod as a non-handed exit only device for 1-3/4 inch doors, though it is standard duty and not fire rated, so it does not carry over to a rated opening.
    19) What finishes does the Von Duprin 3327A come in for matching other hardware in the building?
    Ten finishes: 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. 628 aluminum and 710 dark bronze anodized are the usual matches on aluminum storefront.
