Von Duprin 550DT 26D – Frequently Asked Questions

1) What does the Von Duprin 550DT dummy trim actually do on the door?
The 550DT is a non-operational trim. There's no lever, no cylinder, and no way to retract a latch with it. It mounts on the pull side of a door fitted with a 55 Series exit device to give the opening a finished look, so the door is exit-only from the outside. If you need someone to get in from the outside with a key or lever, a dummy trim is the wrong function and you want a keyed nightlatch or lever trim instead.
2) How far does the 550DT trim stick out from the door face?
Projection on the 550DT is 2-5/8 x 1-7/8 inches. That's a narrow stile profile, so it clears aluminum storefront and glass front doors where a wide escutcheon trim would overhang the stile or foul the glass stop. Worth checking against any adjacent door, frame return, or push bar on a pair before you commit.
3) I'm replacing trim on a pair of aluminum storefront doors. Is the 550DT the right piece for the inactive leaf?
If the leaf carries a Von Duprin 55 Series device and you want the outside face finished with no operating hardware, yes. The 2-5/8 x 1-7/8 inch projection is sized for narrow stile aluminum doors, and because it's non-handed the same part works on either leaf. Order two in the same finish if you're dressing both leaves so the pair matches.
4) What is the closest equivalent to the Von Duprin 550DT if the exit device on the door is not a 55 Series?
The 550DT is a dummy trim built for Von Duprin 55 Series exit devices, so it does not carry over to another manufacturer's device. The direct counterpart on a Detex Value Series opening is the Detex 02BN dummy S-lever trim with blank escutcheon, which is also a dummy function trim in the BN Series. On a Dexter ED1500 device, the equivalent is the Dexter ED1500 Series dummy function exit device trim with handle pull plate. Match the trim to the device family already on the door, because exit trim mounts to that device's through-bolt pattern.
5) The door needs to be openable from the outside with a key, not just pulled - what should be ordered instead of a dummy trim?
A dummy trim like the Von Duprin 550DT is non-operational and gives a finished appearance only; it will not retract a latch. For key-operated outside entry, look at night latch trim such as the Sargent 704ET night latch lever trim with field reversible operation, a Grade 1 heavy duty trim in the 700 Series, or the Sargent 704-ETL night latch lever trim with key retract function in the PE Series, also Grade 1 heavy duty. Corbin Russwin's VT957ET is a nightlatch escutcheon trim in stamped or formed stainless steel for ED5000 Series devices. Each is tied to its own device series, so confirm the device family before ordering.
6) What is the difference between a dummy trim and a passage or exit-only trim on an exit device?
The Von Duprin 550DT is a dummy trim: it is fixed and does not operate the device. A passage trim does operate the latch from the outside without a key, such as the Arrow SRX01 Sierra lever with rose for ED910, S1150 and S1250 devices, or the Corbin Russwin 3310AET passage trim for ED300 Series rim, surface vertical rod and mortise devices. An exit-only trim is a fixed pull with no operating function, like the BEST Precision 2000 Series narrow stile exit only pull trim with cover plate. If someone needs to enter through the door without a key, dummy trim is the wrong choice.
7) Do I have to specify handing when ordering the 550DT exit trim?
No handing to call out. The 550DT is non-handed, so one part covers left and right hand doors. That matters if you're standardizing across a building: you can stock one trim for every 55 Series opening regardless of swing, and the 55 Series device itself is field reversible.
8) Is the 550DT heavy enough for a high traffic entrance?
Grade 1, heavy duty. That's the top ANSI/BHMA durability tier for door hardware, and it's the level you want on school, hospital, and retail entrances where the door cycles all day. Since a dummy trim doesn't operate anything, the grade here is about the trim surviving being pulled and leaned on rather than latch cycles.
9) What finishes does the 550DT dummy trim come in, and can I match older bronze hardware?
Nine finishes: 626 satin chrome, 625 bright chrome, 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 643E aged bronze, 622 matte black, and 693/SPBLK black painted. For a historic or retro building where the rest of the hardware is dark bronze, 613 oil rubbed bronze and 643E aged bronze are the close matches. 626 is the default on most commercial openings.
10) Is there another brand's dummy exit trim if I'm not running Von Duprin devices?
Two in the same function. The Detex 02BN is a dummy S-lever trim with a blank escutcheon for Detex Value Series devices, and the Dexter ED1500T dummy function trim uses a handle pull plate and is Grade 1. Neither one mounts on a Von Duprin 55 Series device, and the 550DT won't mount on theirs. Pick the trim that belongs to the device already on the door.
11) Can a Command Access electrified exit trim replace a Von Duprin dummy trim for access control?
No, those solve different problems. The Von Duprin 550DT is a fixed dummy trim with no operating function. Command Access builds electrified exit trims that run on 12V or 24V with fail safe and fail secure options, including the ET15, ET25 and the 230L, which is an electrified version of the Von Duprin 230L trim for V96, 36 and 23 Series devices. The Command Access ET26 is Grade 1 with a field reversible design. Choosing an electrified trim means running power to the door, which a dummy trim does not require.
12) Which exit device trims match the Grade 1 heavy duty rating of the Von Duprin 550DT?
The 550DT is rated Grade 1 and heavy duty. Peers carrying both a Grade 1 rating and a heavy duty designation include the Sargent 704ET night latch lever trim in the 700 Series and the Sargent 704-ETL night latch lever trim in the PE Series. Falcon's 510L is heavy duty in a classroom function for 24/25 Series devices, and the Pamex E9000 storeroom L3 lever trim is Grade 1 heavy duty. By contrast, the Falcon 179L lever control trim for 1790 Series devices and the Falcon 212L escutcheon lever trim for 20 Series devices are medium duty.
13) What looks like a substitute for the 550DT but will not work on the same door?
Trims that mount independently of the exit device are the common mistake. The Dormakaba E-Plex 5000 Series model 5067 is a mechanical pushbutton mortise lock for wide stile doors, not exit device trim in the sense of a 55 Series companion. The Dormakaba E-Plex 201U electronic pushbutton exit trim and the PowerPlex P201U for rim, mortise and SVR devices carry their own credential hardware and their own device series. The Von Duprin 550DT is dedicated to 55 Series exit devices, and a trim built for a different device platform will not line up with the 55 Series through-bolt pattern.
14) Is a pull trim a reasonable alternative to a dummy lever trim on the inactive leaf of a pair?
It can be, if a graspable pull is acceptable in place of a fixed lever. The Von Duprin 550DT is non-handed dummy trim sized at 2 5/8 inch by 1 7/8 inch projection. Pull alternatives include the BEST Precision 2001 narrow stile exit only pull trim with cover plate and the Dexter ED1500 Series dummy function trim with handle pull plate. Note that some pull trims are prepped for a cylinder and carry an operating function, such as the Tell exit device pull trim with cylinder hole, less cylinder, and the Design Hardware 2P-03NL pull trim with cylinder hole in an entry function, so a blank pull and a keyed pull are not interchangeable.
15) Which exit trims list a door thickness range when standardizing hardware across doors of varying thickness?
The Pamex E9000 storeroom L3 lever heavy duty trim covers 1-3/8 inch to 2 inch doors. The Tell escutcheon and thumbpiece trims cover 1-3/8 inch to 1-3/4 inch: the EDELT53 in keyed entry, the EDELT80 in storeroom, the EDTHP53 thumbpiece trim in keyed entry, and the EDPT pull trim. If a facility has thicker doors in the mix, the Pamex range extends further at the top end.
16) What are the lever style choices if a lever trim is preferred over the 550DT dummy plate?
The 550DT is a dummy trim in the 55 Exit Trim family. If a lever look is wanted, Delaney offers the 500L exterior trim in an entrance function in three lever styles, the CT, MD and SD levers. Accentra uses the Augusta lever across the 426F escutcheon trim for 6000 and 1800 Series devices, the AU-441F night latch keyed lever trim, and the 446F classroom trim. Marks USA offers the M195F storeroom lever and rose trim with spring loaded roses for M9900 touchbar devices. These are operating trims, unlike a dummy.
