Von Duprin 880DT-R 26D – Frequently Asked Questions

1) What does the Von Duprin 880DT dummy trim actually do on the door?
The 880DT is a dummy function trim, which means it gives the outside of the door a pull with no key and no way to retract the latch. Push from inside on the 88 Series device and you get out; from outside the door stays secured until someone opens it from within. If you need the outside to open the door with a key, order a keyed function from the 880 family instead, such as the 880NL nightlatch.
2) Will the 880DT fit my Von Duprin exit device?
It mounts to Von Duprin 88 Series wide-style cross bar exit devices, and only those. The 88 Series covers rim, surface mounted vertical rod, concealed vertical rod, and mortise configurations, and the 880DT works across all of them. If your device is a 99, 33A, or another Von Duprin family, this trim is not the one for it.
3) Do I have to specify a device prep when ordering the 880DT trim?
Yes, that is the one thing you must get right. The 880DT is ordered in three device preps: Rim Prep, Vertical Rod Prep (Surface Applied), and Mortise/Vertical Rod Prep. The prep matches the mounting pattern of the 88 Series device already on the door, so identify whether you have a rim device, a surface vertical rod, or a mortise/concealed rod before you order.
4) Does the 880DT need to be handed for a left hand reverse door?
No handing to call out. The 880DT is non-handed, so a single part covers left and right hand openings and you can set it in the field either way. For a property manager keeping trim on the shelf for a building full of 88 Series devices, that means one trim and one finish covers every door regardless of swing.
5) My door needs the outside handle to unlock with a key or a code, not a dummy pull. What should I look at instead?
A dummy trim will not do that job, so pick a keyed or electronic trim. Within Von Duprin's 880 family the 880NL and 880K are the keyed functions for an 88 Series device. Across other brands, ZenSupply carries the Sargent 704ET night latch lever trim with field reversible operation, the Corbin Russwin VT957ET nightlatch escutcheon trim for ED5000 Series devices, and the Design Hardware KIL storeroom function trim with a Schlage C keyway. For pushbutton access without wiring a strike, the Dormakaba E-Plex 201U electronic pushbutton exit trim is a wide stile option.
6) What trim should I use instead of the 880DT if the outside needs to unlock with a key?
The 880DT is a dummy trim function, so it is fixed and does not retract the latch. For a keyed exterior, nightlatch trims include the Sargent 704ET, a Grade 1 heavy duty night latch lever trim with field reversible operation, and the Sargent 744, a Grade 1 night latch trim for surface vertical rod and mortise 8700 and 8900 Series devices. The Corbin Russwin VT957ET is a nightlatch escutcheon trim in stamped or formed stainless steel for ED5000 Series devices, and the Accentra 121NL is a nightlatch trim. Each preps to its own device family.
7) I need a lever on the outside that always operates, not a fixed dummy. What replaces the 880DT?
The 880DT is a dummy trim, so the lever or pull is fixed. Passage function trims give a lever that always retracts the latch: the Corbin Russwin 3310AET is a passage function trim for rim, surface vertical rod, and mortise ED300 Series devices, the Corbin Russwin x910ET is a passage function heavy-duty trim for ED5200S, ED5200, ED5400, and ED5800 Series devices, and the Arrow SRX01 is a passage function Sierra lever with rose for ED910, S1150, and S1250 devices. The Marks USA M195N is a passage leverset trim in the M195N Series.
8) My door is narrow stile aluminum. Will the 880DT work, or do I need something else?
The Von Duprin 880DT is made for the 88 Series wide-style cross bar platform. For narrow stile openings, BEST lists the 2001 exit only pull trim with a cover plate and the 2901 exit only lever trim, both narrow stile, for 2000 Series exit devices. BEST's wide stile equivalents are the 1701 pull trim and the 4901 lever trim. Stile width governs how much room the trim has on the door face, so confirm it against the device before ordering.
9) Where does the 880DT trim land vertically on the door?
Center line height depends on the device it goes with. On a rim device the centers are A 39-13/16 inches (1011 mm) and B 33-11/32 inches (847 mm). On a mortise lock or a surface mounted vertical rod device it is A 39-13/16 inches (1011 mm) and B 33-1/2 inches (851 mm). Use those to lay out the through-bolt holes and to confirm the trim clears any existing prep, glass stop, or vision lite on the door.
10) How far does the 880DT stick out from the door face?
Projection is 2 inches (51 mm) off the door face. That matters on a pair of doors with a narrow reveal, on an opening next to a wall return, or anywhere a door has to swing past an adjacent leaf or handrail without the trim catching.
11) Is the 880DT heavy enough for a school or hospital entrance?
It is built for that traffic. The trim is fabricated from heavy 10 gauge (2.4 mm) brass, bronze, or stainless steel and carries a Grade 1 Heavy Duty rating, which is the top rating tier for commercial door hardware. It is a commercial product, not a residential one, and Von Duprin lists it for offices, schools, healthcare, retail, warehouses, multi-tenant residential, and government buildings.
12) I want a plain pull on the outside of an 88 Series device but no trim at all on some doors. What are my options?
Two different parts. The 880DT gives you a dummy trim with a pull on the outside. If the door needs no outside operation at all, Von Duprin offers the 880EO exit only trim plate, which is ordered together with the device as 88EOx880EO rather than as a loose trim. The rest of the 880 family covers the keyed and lever options: 880K, 880NL, and 880TP.
13) Can I use the 880DT on a fire rated opening?
The 88 Series device platform it mounts to is listed for panic and fire rated applications, and since the 880DT is a dummy trim it adds no outside latch retraction that would interfere with the device's operation. The fire label on the opening follows the exit device and the door assembly, so match the trim to the specific 88 Series device already listed for that opening.
14) I have a pair of doors with 88 Series vertical rod devices. Do I need two 880DT trims?
One per leaf that needs an outside pull. On a pair with surface mounted vertical rod devices you would order the Vertical Rod Prep (Surface Applied) version for each active leaf; the center line for that prep is A 39-13/16 inches (1011 mm) and B 33-1/2 inches (851 mm), the same on both leaves. Since the trim is non-handed, the left and right leaf take the identical part number and finish.
15) Which dummy or blank trims can I standardize on across a facility with mixed exit device brands?
Fixed, non-operating trims exist across several device families. The Von Duprin 880DT covers 88 Series devices non-handed with a 2 inch (51 mm) projection. The Detex 02BN is a dummy S-lever trim with a blank escutcheon for Value Series devices, the Dexter ED1500T-DUMM-PULL is a dummy function trim with a handle pull plate for ED1500 Series devices, and the Falcon 212L is a blank escutcheon trim for 20 Series devices with shear pin protection. Trim is device-specific, so a facility standard has to be set per device family rather than one part number across all doors.
16) Which exit trim should I specify for a classroom door instead of a dummy trim?
A dummy trim like the 880DT does not control access, so a classroom function trim is the substitute. The Falcon 510L is a heavy duty classroom function trim with a lever handle for 24 and 25 Series devices. The Accentra 446F is a Grade 1 classroom function exit device trim with an Augusta lever. The Dexter ED1000T-CLRM-TP-NC is a Grade 1 classroom trim supplied as thumbpiece by pull plate by cylinder, less cylinder, if a thumbpiece suits the opening better than a lever.
17) Can I put an access control reader or electrified trim on an 88 Series door instead of the 880DT?
The 880DT is a mechanical dummy trim with no electrical function. For electrified control, Command Access makes the 230L, an electrified Von Duprin 230L exit trim with 12V/24V operation and fail safe or fail secure options for V96, 36, and 23 Series devices, and the ET26, an electrified exit trim with Grade 1 construction and a field reversible design. Falcon offers the 510L-FSA/FSE, an electrified heavy duty trim with a lever handle for 25 Series devices. For standalone credential control, the Dormakaba E-Plex 201U is an electronic pushbutton exit trim for wide stile doors.
18) I have a 1-3/4 inch door and need a keyed entry trim rather than a dummy. What are my options?
The 880DT is a non-handed dummy trim and takes no cylinder. For keyed entry, the Tell EDELT53 is an escutcheon lever trim with entry function for doors 1-3/8 inch to 1-3/4 inch, and the Tell EDTHP53 is the thumbpiece version of the same entry function across the same door thickness range. Design Hardware lists the LE08 entry function trim with a flat lever and escutcheon for 1000R and 2000R devices, Grade 1, and the KIL entry function trim in a Schlage C keyway if the building keys to Schlage C.
19) What finishes can I get the 880DT dummy trim in to match the rest of my openings?
Eleven finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 629 bright stainless steel, 643E aged bronze, and 693 black painted. All eleven are offered on each of the three device preps, so you can standardize a building on one finish whether the doors carry rim, surface vertical rod, or mortise 88 Series devices.
20) Is there a lighter duty exit device trim than the Von Duprin 880DT?
The 880DT carries a Grade 1 Heavy Duty rating for commercial use. Falcon lists medium duty trims in the same category: the 179L lever control trim for 1790 Series devices, classroom function, medium duty, and the 212L escutcheon lever trim for 20 Series devices with shear pin protection, also medium duty. Falcon's 510L is heavy duty if you want to stay at the same duty level in that brand. Duty level and device family both need to match the opening, so check which device is installed before choosing.
