Von Duprin 88EO-F US26D-3 – Frequently Asked Questions

1) Will the Von Duprin 88F rim exit device work on a fire rated door?
Yes, that's exactly what the 88F is for. The 88F is fire rated and certified to ANSI/BHMA A156.3, 2008 Grade 1, with ANSI/UL 10C and CAN/ULC-S104 listings for fire rated door assemblies. Because it's a fire device it ships less dogging, which is correct for a fire opening: the latch must never be held retracted. If you want a device you can dog open during business hours, you need a non-fire rim device instead.
2) What door thickness and door type does the Von Duprin 88 Series rim device fit?
The 88F is built for 1-3/4 inch doors only, which is the standard commercial thickness. It is not rated for wood doors; it covers stock hollow metal doors with 86 or 161 cutouts. If you're hanging it on a wood door or anything thicker than 1-3/4 inches, this is the wrong device.
3) Do I need to order the Von Duprin 88F by hand?
The 88 Series device is non-handed and field reversible, so one device covers both a left hand reverse and a right hand reverse opening. Handing is still called out on the order (RHR or LHR) so it arrives set up the way your door swings, but if the opening turns out opposite in the field, you reverse it on site rather than reordering.
4) Will the Von Duprin 88 rim exit device latch into the strike I already have?
The 88 latches with a 3/4 inch throw into a surface rim strike mounted on the frame stop, not into an ANSI mortise lock prep. If your existing opening has a Von Duprin style rim strike from another rim device, the geometry is the same class of prep, but a mortise or vertical rod opening will need the rim strike added. Mount height matters too: the device centerline sits at 39-13/16 inches from the finished floor.
5) Can I use a rim exit device on a pair of doors, or do I need vertical rods?
A rim device latches into the frame or into a mullion, so on a pair of doors the 88 works with a removable mullion between the leaves. The 88F is UL listed for installations on single and double doors with mullion. If you cannot have a mullion in the opening, a rim device is the wrong choice and you want vertical rods instead: the 88 Series is also built as a surface vertical rod (27) and concealed vertical rod (47), plus a mortise lock (75) version.
6) What trim can I get with the Von Duprin 88 crossbar device, and what do I order for exit only?
Trim function is specified on the order. Ten choices: EO exit only (no outside trim at all), NL night latch, K knob, K-BE knob with blank escutcheon, K-NL knob with night latch, L lever, L-BE lever with blank escutcheon, TP thumb piece, TP-BE thumb piece with blank escutcheon, and DT dummy trim. Pick EO for a pure egress door where nobody re-enters. If you choose L or L-BE you also pick the lever design: 06 (default), 01, 02, 03, 07 or 17.
7) What else is a fire rated Grade 1 rim exit device I could use instead of the Von Duprin 88F?
Closest peer on the same door is the Sargent 8800 Series wide stile rim device, fire rated and Grade 1. The Dexter ED1000 Series fire rated rim device is also Grade 1. If you only need exit only with no outside trim, the Marks USA M9900F comes fire rated in 36 inch and 48 inch, and the Orca OED85 Series is a fire rated 36 inch exit only rim device. All of those are fire rated; a non-fire device cannot substitute onto a rated opening no matter how close the rest of the spec looks.
8) Can the Von Duprin 88F-3FT go on a wood door, and what rim device should I use if it cannot?
The Von Duprin 88F-3FT is not wood door compatible; it is built for hollow metal doors at 1-3/4 inch thickness. For a wood door on a fire rated opening, the Adams Rite 3700 Series 30 inch fire rated rim exit device is wood door compatible and carries Grade 1 with a fire rating. Note the format change: the Adams Rite 3700 is a narrow stile device with starwheel interlocking at 30 inches, where the 88F-3FT is a 36 inch wide stile crossbar device. Confirm the stile width on the wood door before ordering, since a narrow stile device and a wide stile device do not share a prep.
9) What is the closest fire rated wide stile rim exit device to the Von Duprin 88F-3FT?
The Sargent 12-8810-LTRIM is the nearest match on the core specs that matter for a fire rated opening: it is a fire rated wide stile rim exit device carrying Grade 1, the same fire rating and Grade 1 certification and the same wide stile format as the 88F-3FT. The difference is in the operating bar and the trim. The Von Duprin 88F-3FT uses a crossbar and is offered in less dogging form as fire rated openings require, while the Sargent 8800 Series device is supplied with L trim and RX. If the crossbar look is what the other doors in the building already carry, stay with the 88F-3FT; if a push pad reads acceptable on the opening, the Sargent 12-8810-LTRIM covers the same fire and grade requirement.
10) What is a simpler fire rated 36 inch rim exit device if the door only needs exit only egress?
Two fire rated 36 inch rim devices are built for exit only and skip the trim selection entirely: the Marks USA M9900F 36 inch fire rated rim exit device, which is exit only with a panic protector end cap, and the Orca Hardware OED85 Series 36 inch fire rated rim exit device, also exit only. Both carry a fire rating like the Von Duprin 88F-3FT. The 88F-3FT covers a much wider range of outside trim, including knob, lever, thumb piece, night latch and dummy trim, so it is the one to specify when the opening needs keyed or lever entry from the outside. When the door is pure egress with no outside operation, the M9900F-36 or the OED85 answers the same fire rated requirement with a single part number.
11) The opening is a 48 inch door and needs a fire rated rim device - what replaces the Von Duprin 88F-3FT there?
The Von Duprin 88F-3FT is sized at 36 inches. For a 48 inch fire rated opening, the Marks USA M9900F 48 inch fire rated rim panic exit device is the direct answer in the same fire rated rim format, supplied exit only with a panic protector end cap. It is a device only solution, so an opening that needs outside lever or knob entry is a different conversation than one that needs egress alone.
12) What looks like a substitute for the Von Duprin 88F-3FT but is not a fire rated exit device?
The SDC MSB550 Series 36 inch mechanical switch bar and the SDC SureExit PSB560 Series 36 inch pressure sense bar both mount at 36 inches on narrow or wide stile doors and read as exit bars, but they are switching devices rather than latching rim exit devices - the MSB550 works with electromagnetic lock release and the PSB560 is a pressure sense bar - and both are listed as not fire rated. The Securitron EMB is likewise an electromechanical exit bar, listed for 2-1/4 inch door thickness rather than the 1-3/4 inch the 88F-3FT is built for. On a fire rated opening that needs a mechanical latch with a 3/4 inch throw, none of the three replaces the 88F-3FT.
13) Which rim exit device should I use if the door is narrow stile instead of wide stile?
The Von Duprin 88F-3FT is a wide stile device and will not fit a narrow stile door. On a fire rated narrow stile opening, the Adams Rite 3700 Series 30 inch is fire rated, Grade 1 and narrow stile. For non rated narrow stile openings, the Corbin Russwin ED4200 is a Grade 1 36 inch narrow stile rim device that accepts trim, the Falcon 19-R is a Grade 1 36 inch narrow stile exit only device, and the Adams Rite 8800 Series 30 inch is Grade 1 narrow stile with a 1-3/4 inch to 2-1/4 inch door thickness range. Check the fire rating on the assembly first, since only the Adams Rite 3700 among those is fire rated.
14) If the exit device needs hex key dogging, what should I look at instead of the Von Duprin 88F-3FT?
The Von Duprin 88F-3FT is supplied less dogging, which is what a fire rated assembly calls for. When the opening is not rated and you want the bar dogged down during business hours, the Design Hardware 1000R 33 inch heavy duty rim device and the Design Hardware 2000R 33 inch standard duty rim device both come with hex key dogging, and the Stanley Security QED200 Series is a Grade 1 heavy duty narrow stile rim device with hex key dogging. None of those three is a fire rated device, so keep the 88F-3FT on any rated door.
15) How much does the Von Duprin 88 crossbar device stick out from the door face?
Projection is 4-3/4 inches off the door face. That's the number to check against any door in a tight vestibule, a corridor with a clear width requirement, or an opening where the leaf swings back against a wall. The case footprints are 6 x 1-3/4 x 15/16 inches at the hinge stile and 8-1/4 x 2-3/4 x 15/16 inches at the lock stile.
16) Can I tie a Von Duprin 88 exit device into my access control system?
Yes. The 88 Series takes the E8875 electrified option for access control or fire alarm integration, and an RX request-to-exit switch that signals the panel whenever someone pushes the bar. RX is selected on the order (None or RX), so specify it up front if the door is monitored.
17) What is the difference between the standard, RCB and KN crossbar on a Von Duprin 88?
Three crossbar choices. Standard is the plain crossbar. RCB is a reinforced crossbar, worth specifying on high abuse openings like schools, loading areas and back-of-house doors. KN is a knurled crossbar, a tactile hazard warning surface used where code or the facility requires occupants to feel by touch that the door leads somewhere hazardous. Pick the crossbar when you order; it is not a field swap decision.
18) Is the 36 inch Von Duprin 88 device cut down for narrower doors?
The 88F-3FT is the 3 foot (36 inch) device and it is field sizeable, so a narrower leaf is handled by trimming on site rather than by ordering a different length. Note this is a wide stile device, so the door needs a wide stile to accept it. On aluminum storefront or any narrow stile leaf, you want a narrow stile rim device instead, such as the Adams Rite 3700 Series, which is also fire rated and Grade 1.
19) Do I need to buy mounting hardware separately for the Von Duprin 88 exit device?
No extra fastener order needed. All necessary mounting fasteners come with the 88 device. What you do specify separately is the outside trim function, the lever design if you chose lever trim, the crossbar type, the finish, and the RX switch if the door is monitored. On a pair, the mullion is a separate item.
20) Which crossbar rim exit devices are comparable to the Von Duprin 88 Series but are not fire rated?
Two crossbar rim devices sit in the same wide stile crossbar format without a fire rating: the Corbin Russwin ED3200, a Grade 1 48 inch crossbar rim exit device for wide stile doors at 1-3/4 inch thickness, and the CRL Jackson 1095 Series 48 inch crossbar rim panic device, a wide stile exit only device. Both are listed with a fire rating of no, so neither belongs on a fire rated door assembly. The Von Duprin 88F-3FT is the crossbar device to specify when the opening is in a fire rated assembly; the Corbin Russwin ED3200 or the CRL Jackson 1095 keeps the crossbar appearance on a non rated 48 inch opening.
21) Are there Grade 2 alternatives to the Von Duprin 88F-3FT for a lower traffic opening?
The Cal-Royal 5000 is a 36 inch wide rim exit device with a touch bar and a Grade 2 chassis, rated heavy duty and not fire rated. The Cal-Royal A9800 Series 36 inch exit only device is likewise Grade 2 and heavy duty. Both step down from the Grade 1 certification the Von Duprin 88F-3FT carries, and neither is fire rated, so they suit a non rated interior opening rather than a rated assembly. Where a facility standard calls for Grade 1 across all egress hardware, the 88F-3FT is the one that meets it.
22) I need request to exit monitoring on an exit device - how does the Von Duprin 88F-3FT compare to the Sargent 12-8810?
Both cover it. The Von Duprin 88F-3FT is offered with an RX request to exit switch as an ordering option alongside a no switch version, so the monitoring is selected as part of the device. The Sargent 12-8810-LTRIM is a fire rated wide stile Grade 1 device supplied with RX and MELR and L trim as a fixed build. The practical difference for an integrator is configurability: the 88F-3FT lets you pick the trim function and finish independently of the switch, where the Sargent part arrives as a set configuration.
23) Does the Arrow FS1250 work in place of the Von Duprin 88F-3FT?
The Arrow FS1250 is a fire rated 32 inch rim exit device for 1-3/4 inch doors and is not wood door compatible, so it shares the fire rating and the door thickness with the Von Duprin 88F-3FT. The size is the split: the FS1250 is 32 inches where the 88F-3FT is 36 inches. Confirm the door width against the device length before substituting, and note the 88F-3FT is non handed and field reversible, so one part covers both hands of a pair.
24) Which rim exit device matches the Von Duprin 88F-3FT if the facility standard is extra heavy duty wide stile?
The Detex 10 Advantex Series 36 inch is a wide stile rim exit device rated extra heavy duty and Grade 1 at the same 36 inch length as the Von Duprin 88F-3FT, and the Detex V4003A wide stile device is Grade 1 with night latch trim. Both are wide stile Grade 1 like the 88F-3FT. The Detex 10 is listed as not fire rated, so on a rated assembly the 88F-3FT remains the device that carries the fire rating along with Grade 1.
25) The opening needs vertical rod rather than rim - what takes the place of the Von Duprin 88F-3FT?
The 88F-3FT is a rim device, which latches to a strike on the frame or a mullion. For a pair of doors latching top and bottom instead, the Hager 4501 Series 36 inch is a Grade 1 concealed vertical rod device with a wide stile pushpad, and the Hager 4601 Series 36 inch is the Grade 1 concealed vertical rod device in narrow stile. Both are listed as not fire rated, so a rated pair is a different specification. The 88 Series itself supports surface vertical rod and concealed vertical rod configurations, which is worth confirming before you change brands to solve a rod requirement.
26) What finishes does the Von Duprin 88 Series crossbar exit device come in?
Nine finishes, so you can match the 88 to whatever is already on the other openings: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome, 626 satin chrome, 643E aged bronze and 693 black. For a building standardizing on one look, 626 satin chrome and 630-family satin finishes are the usual institutional pick; 613 and 643E suit a darker architectural package.
