Von Duprin 880K-BE-R 26D – Frequently Asked Questions

1) Will the Von Duprin 880K-BE trim work on my 88 Series exit device, or do I need a different trim for a vertical rod device?
The 880K-BE is made for Von Duprin 88 Series exit devices, and it is ordered to match the device prep. Three prep choices cover the family: Rim Prep, Mortise Prep, and Vertical Rod Prep. So a surface or concealed vertical rod 88 device takes the Vertical Rod Prep version, an 88 rim device takes Rim Prep, and an 88 mortise device takes Mortise Prep. Pick the prep off the device you already have on the door, not off the door type.
2) What does the Passage Knob with Blank Escutcheon function on the Von Duprin 880K do on the outside of the door?
Passage means the outside knob always retracts the latch, with no key and no locking. The escutcheon is blank, so there is no cylinder hole in the plate. That makes it the right trim for a door that has to stay usable from the outside all the time (a stairwell that is not secured, a vestibule, a corridor pair), and the wrong trim if anyone needs to lock that opening from the outside. For a keyed outside function on the same kind of door, look at a nightlatch or storeroom trim instead, such as the Sargent 704ET night latch lever trim.
3) What height do I mount Von Duprin 88 Series exit trim at?
Von Duprin publishes center line dimensions for the 88 Series, and they differ by device type. Rim: A 39 13/16 (1011 mm), B 36 13/16 (935 mm). Surface mounted vertical rod: A 39 13/16 (1011 mm), B 38 5/16 (973 mm). Mortise lock: A 39 13/16 (1011 mm), B 38 9/16 (979 mm). The A dimension is the same across all three, the B dimension is what changes, so a door prepped for one device type is not automatically prepped for another.
4) I want a lever instead of a knob on my exit device trim - what are my options?
The 880K-BE is a knob trim with a blank escutcheon. If the opening calls for a lever with the same free passage operation, the Arrow SRX01 is a passage function Sierra lever with rose for ED910, S1150 and S1250 devices. The Corbin Russwin 3310AET is a passage function lever trim for ED3000 Series rim, surface vertical rod and mortise devices. Both are passage, meaning the trim always retracts the latch and nothing is keyed. Levers are also the answer where a facility standardizes on lever hardware for accessibility reasons across a door schedule.
5) What is the equivalent passage-function exit device trim for a Corbin Russwin ED4000 device?
The Von Duprin 880K-BE is a passage function trim built for Von Duprin 88 Series exit devices, so it does not go on a Corbin Russwin device. For an ED4000 Series opening, the matching passage function trim is the Corbin Russwin x810ET, which covers SecureBolt, rim, surface vertical rod and concealed vertical rod devices. On ED5200S, ED5200, ED5400 and ED5800 devices the passage function trim is the Corbin Russwin x910ET, and on ED3000 Series devices it is the 3310AET, which covers rim, surface vertical rod and mortise. Match the trim to the device series first; passage function is the same operation in all four cases.
6) The 880K-BE is passage - I need the outside trim to be keyed. What do I use instead?
A passage knob such as the 880K-BE always allows entry from the outside; nothing locks it. When the door needs key control from the outside, the function changes, not just the handle. Nightlatch trim, where the key retracts the latch and the trim is otherwise rigid, is available as the Sargent 704ET, a Grade 1 heavy duty night latch lever trim with field reversible operation, and the Sargent 704-ETL in the PE Series with key retract. The Corbin Russwin VT957ET is a nightlatch escutcheon trim for ED5000 Series devices. For storeroom function, where the lever is locked outside until keyed, the Tell EDELT80 is a storeroom escutcheon lever trim and the Pamex E9000 is a Grade 1 storeroom L3 lever heavy duty trim.
7) Do I have to specify handing when I order Von Duprin 880 Series exit trim?
No handing to call out. The 880 trim is non-handed, so one part covers left and right hand doors. For a property manager buying several openings at once, that means one line item instead of splitting the order by swing, and no wrong-hand returns.
8) How much does the Von Duprin 880K knob trim stick out from the door face?
Projection is 2 3/4 inches (70 mm) off the door. That matters where a door swings into a tight vestibule, near a wall return, or next to an adjacent door leaf, and it is the number to check against clearance on the pull side before you commit to knob trim.
9) Is the Von Duprin 880K-BE trim Grade 1, and is it heavy enough for a school or hospital corridor?
Grade 1, heavy duty, and built for commercial use. The trim is fabricated from heavy 10 gauge (2.4 mm) brass, bronze, or stainless steel. That is the specification level facility and MRO buyers standardize on for high traffic openings in schools, healthcare, and government buildings.
10) I want the outside of the door to be exit only with no knob at all. Do I still order the 880K-BE?
No. Exit only means no operating trim on the outside, and the 880 family covers that with the 880EO exit only trim plate. Ordered together with the device you would specify 88EOx880EO. The 880K-BE is the opposite case: a knob that always lets people back in. Other functions in the 880 line are 880DT, 880K, and 880NL.
11) Will the Von Duprin 880K-BE trim work on a fire rated door with an 88 Series device?
The 88 Series is offered in rim, surface mounted vertical rod, concealed vertical rod, and mortise configurations for panic and fire rated applications, and the 880 trim is made for that full range. Note the function though: passage trim leaves the outside always operable, which is often not what a fire rated stair or corridor door needs. If the opening has to stay secure from the outside, order a keyed function from the 880 line instead.
12) Can I get access control on the outside of my exit device instead of mechanical passage trim?
The 880K-BE is mechanical passage trim with no electrical function. If the opening needs to be released or locked electrically, electrified exit trim replaces it. Command Access offers the ET15, ET25 and ET26 electrified exit trims with 12V and 24V operation and fail safe or fail secure options, with the ET26 built to Grade 1 with a field reversible design; the Command Access 230L is an electrified version of Von Duprin 230L trim for V96, 36 and 23 Series devices. For standalone credential control without wiring to an access system, the Dormakaba E-Plex 201U is an electronic pushbutton exit trim for wide stile devices, and the PowerPlex P201U covers rim, mortise and surface vertical rod devices.
13) Is Falcon 212L blank escutcheon trim the same thing as the Von Duprin 880K-BE?
They share the blank escutcheon description but they are not interchangeable. The Falcon 212L is a 20 Series escutcheon lever trim with shear pin protection, rated Medium Duty. The Von Duprin 880K-BE is a knob trim built for 88 Series exit devices and rated Grade 1 Heavy Duty. Two things separate them for an ordering decision: the device series each one mounts to, and the duty rating, which matters on a high traffic opening or where a specification calls out heavy duty trim.
14) What Grade 1 heavy duty exit trim options are there besides the Von Duprin 880K-BE?
The 880K-BE is rated Grade 1, Heavy Duty for commercial use. Other Grade 1 heavy duty exit trims include the Sargent 704ET and 704-ETL night latch lever trims and the Pamex E9000 storeroom L3 lever, which fits doors 1-3/8 inch to 2 inch thick. The Sargent 744 is Grade 1 night latch trim for surface vertical rod and mortise 8700 and 8900 Series devices. Dexter ED1500T and ED1000T are also Grade 1 trims. The dividing question is not the grade, which several of these share, but which device series the trim mounts to and what function the opening needs.
15) What is the difference between a blank escutcheon trim and a trim with a cylinder hole?
A blank escutcheon, as on the Von Duprin 880K-BE, has no cylinder preparation because the passage knob is never keyed. Trims prepared for a cylinder are a different order: the Tell EDPT is an exit device pull trim with a cylinder hole supplied less cylinder, and the Design Hardware 2P-03NL is a Grade 1 pull trim with a cylinder hole in night latch form for 1000R and 2000R devices. Trims sold less cylinder, including the Corbin Russwin VT957ET nightlatch escutcheon and the Dormakaba YR03R wide stile nightlatch lever escutcheon, need a cylinder specified separately in the keyway the building uses. If the door never needs a key on the outside, a blank escutcheon removes that line item entirely.
16) Is there a trim that works on rim, mortise and vertical rod devices, or do I need a different part for each?
The Von Duprin 880K-BE is non-handed and is prepared for the device type, offered in rim prep, mortise prep and vertical rod prep so one model number covers all three 88 Series configurations with the right prep selected. Peers handle this the same way: the Corbin Russwin 3310AET covers rim, surface vertical rod and mortise on ED3000 Series devices, the x810ET covers SecureBolt, rim, surface and concealed vertical rod on ED4000 Series, and the Dormakaba PowerPlex P201U covers rim, mortise and SVR devices. The Sargent 744 is narrower, built for surface vertical rod and mortise 8700 and 8900 Series devices.
17) What finishes does the Von Duprin 880K-BE knob trim come in, and can I match the other hardware in the building?
Eleven finishes, and all eleven are offered on each of the three device preps: 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/US32 bright stainless steel, 643E aged bronze, and 693/SPBLK black painted. 626 satin chrome is the usual commercial match on aluminum and hollow metal openings; 629 pairs with stainless entrances.
