Break-Away Protection Design

All lever trims feature standard break-away protection to prevent permanent damage from vandalism and abuse. When the lever is forced past the locking point, it drops down and appears broken. The internal disengaging clutch mechanism allows the lever to be easily reset by pulling it back to its original position, eliminating costly repairs and maintaining security functionality.

Why Choose Detex Quality?

Detex exit device trim products deliver professional-grade reliability with heavy-duty construction designed to match the durability of Detex panic devices. The break-away lever design and internal disengaging clutch provide vandal resistance while maintaining easy reset capability. Engineered for demanding commercial applications where dependable performance and security are essential.

Detex 02DNFSB 1016 RHR – Frequently Asked Questions

1) Will Detex FSB lever trim work on my 40 Series exit device?
Yes. The Detex FSB narrow stile lever trim is built specifically for Detex 40, 50 and 51 Series exit devices. It is not a universal trim, so it won't mount to another brand's rim device. If you're trimming a Von Duprin, Sargent or Corbin Russwin device, you need that manufacturer's own trim for the matching series.
2) Do I have to order Detex FSB lever trim handed?
Yes, handing is part of the order. The FSB trim is built Left Hand Reverse or Right Hand Reverse, which are the two handings exit devices use since the door always swings out. Stand outside the door: if the hinges are on your right and the door pulls toward you, it's right hand reverse.
3) What is the difference between the 08 and 09 functions on Detex FSB trim?
Both are key-controlled lever functions. Function 08 lets the key lock or unlock the outside lever, and the lever stays in whatever state you left it. Function 09 also locks and unlocks by key, but the trim returns to locked when the key is removed, so it can't be left unlocked by accident. Function 02 is a dummy lever with no latch retraction at all, and 14 leaves the lever always active for free outside entry.
4) Will this lever trim fit an aluminum storefront door with a narrow stile?
That's what it's for. The FSB is a narrow stile trim, so the escutcheon and lever footprint suit doors with limited stile width, the typical aluminum glass front. Wide stile trim like the Sargent 802 for PE80 devices or Von Duprin's 370 Series escutcheon is sized for hollow metal and wide stile openings instead.
5) What lever trim works with an Arrow S1150 exit device instead of the Detex FSB narrow stile trim?
The Detex DNFSB lever trim is built for Detex 40/50/51 Series exit devices, so it will not mount to an Arrow chassis. For Arrow openings, the Arrow SRX87 trim is made for the S1150/S1250/ED910/PEC910 Series and comes in classroom function with a Sierra lever on a rose, prepped for 1-3/4 inch doors. Match the trim to the device brand and series rather than to the lever shape.
6) I need a classroom-function trim for a Corbin Russwin ED2200 device, not a Detex. What is the equivalent?
The Detex DNFSB covers classroom-style control through its 08 and 09 models, where the key locks and unlocks the lever, but only on Detex 40/50/51 Series devices. On a Corbin Russwin ED2200 or ED2400, use the Corbin Russwin K157ET, a Grade 1 heavy duty key-only trim with rose in classroom function for that series.
7) What is the difference between the Detex 02 dummy lever trim and a blank plate or escutcheon trim?
The Detex DNFSB 02 is a dummy lever: the lever is present and can be grabbed, but it does not retract the latch. A blank trim has no lever at all. The Sargent 802 is a Grade 1 blank plate trim with GTB design for PE80 Series devices and is not rated for wood doors, and the Von Duprin 379L-BE is a Grade 1 heavy duty blank escutcheon for 55 Series rim devices. Choose the dummy lever if you want the outside to look and feel like a working lever, and a blank if you want no outside operation at all.
8) Is there a keyless alternative to the Detex FSB key-operated lever trim for a panic device?
The Detex DNFSB 08 and 09 models rely on a key to lock and unlock the lever. If you want to eliminate keys, the Lockey 115P is a heavy duty keyless passage lever panic trim with a 1150 lock body for doors 1 3/16 to 2 inches thick, and the Lockey 285P is a keyless mechanical panic trim with a lever handle over the same thickness range. For electronic credential control, the Dormakaba E-Plex E5010 is a Grade 1 push button exit device lever trim with key override for 1-3/8 to 2-1/4 inch doors, and the BEST EXZ is an electronic keypad exit device trim with key override in the EZ Series.
9) Can I change the function later without pulling the exit device off the door?
Yes. The FSB trim mounts to a device mounting plate, so a function change is done by swapping the outside trim only. The exit device itself stays on the door. That matters for a property manager who starts with an always-active lever on a tenant entrance and later needs key control on it.
10) What happens if someone forces the lever on this Detex trim?
It gives before it breaks. Forced past the locking point, the lever drops down and looks broken, but an internal disengaging clutch means you just pull it back up to its original position to reset it. No parts to replace, no lock to rekey. Break-away is standard on every lever in the FSB line, not an extra you specify.
11) I need keyless code entry on an exit device instead of a keyed lever. What should I look at?
The Detex FSB is a mechanical keyed or dummy lever trim, so it won't give you code entry. For pushbutton access on a panic device, look at the Dormakaba E-Plex E5010 electronic trim with key override, rated Grade 1 for 1-3/8 to 2-1/4 inch doors, the BEST EXZ keypad trim with key override, or the mechanical Lockey 285P keyless panic trim for 1-3/16 to 2 inch doors. Each of those still has to match the exit device series you already have.
12) I just need a pull on the outside of the exit device, not a lever. Is this the right trim?
No. The FSB is a lever trim, so if the outside only needs a grab point choose a pull or blank instead: the Sargent 862 offset pull, the Sargent 814 PSB nightlatch pull for 80 Series, or a blank plate such as the Sargent 802 or the Von Duprin 379L-BE for 55 Series rim devices. Match the trim to the device series on your door.
13) Which Detex FSB function should I order for a classroom door?
Function 08 or 09. Both let a key lock and unlock the outside lever from the corridor side while the panic device always allows free egress. Choose 09 if you want the lever to go back to locked as soon as the key comes out, which is the safer default for lockdown. Function 14 keeps the lever always active and is wrong for a room that needs to be secured.
14) If I only need a pull with no lever on the outside, what should I use instead of the Detex FSB lever trim?
The Detex DNFSB is a lever trim in all configurations, including the 02 dummy lever, so the outside always carries a lever. If the opening calls for a pull instead, the Sargent 814 PSB is a heavy duty nightlatch pull trim for 80 Series devices, and the Sargent 862 is a Grade 1 offset pull handle for P800 Series devices. Both keep the outside grip without a rotating lever.
15) Can I use a Deltana lever trim in place of the Detex narrow stile FSB trim?
They serve different devices. The Detex DNFSB is narrow stile trim for Detex 40/50/51 Series devices and offers dummy, key-locking, and always-active lever functions. The Deltana trims are matched to their own exit devices: the LTED80LS is entry function and the LTED80LP is passage function for the Exit Device 80, the DDS-36 is storeroom function for the Exit Device 80, and the LTED60LST is storeroom function for the Exit Device 60. Pick the Deltana part only if the device on the door is the matching Deltana 60 or 80.
16) Will the Detex narrow stile FSB trim work on a wide stile aluminum or hollow metal door setup?
The DNFSB is designed as narrow stile trim for doors with limited stile width, and it pairs with Detex 40/50/51 Series devices. If the opening is a wide stile assembly, that is a different device platform entirely; the ACSI ED4200-W036, for example, is a Grade 1 wide stile rim exit device with 24 volt electric latch retraction. Confirm the stile type of the door before ordering trim.
17) I want the outside lever always unlocked. Is the Detex 14 model the right pick or should I use a passage trim from another brand?
The Detex DNFSB model 14 is the always-active lever and is the correct choice when the device is a Detex 40/50/51 Series. On other platforms the equivalent is a passage trim: the Deltana LTED80LP is passage function for the Exit Device 80, and the Lockey 115P is a keyless passage lever panic trim with a 1150 lock body for doors 1 3/16 to 2 inches thick.
18) Which trims offer vandal resistance comparable to the Detex break-away lever?
The Detex DNFSB uses a break-away lever with an internal disengaging clutch: forced past the locking point the lever drops and appears broken, then resets by pulling it back. Among other approaches to abuse resistance, the Sargent 802 blank plate for PE80 Series and the Von Duprin 379L-BE blank escutcheon for 55 Series rim devices remove the lever from the outside altogether, and both are Grade 1. The break-away keeps a usable lever; the blank removes the target.
19) How many lever designs does the Detex FSB trim come in?
Eight lever styles: 1016, 1035, 1058, 1075, 1076, 1093, 1119 and 1147. If you're standardizing a building, pick one style number and carry it across every opening so the FSB trim matches the passage and office levers elsewhere in the facility.
20) Is there an option for hospital or food service use on this Detex lever trim?
An anti-microbial (AM) coating is offered on all FSB levers, which is the reason it turns up on patient corridors, clinics and kitchen exits. It's an option you specify, not the default.
21) Is the Detex FSB trim suitable for a high traffic commercial entrance?
It's a commercial-duty trim, built to the same durability standard as Detex panic devices, and it's used on office buildings, schools, hospitals, retail, warehouses, apartment buildings and municipal facilities. The break-away lever is the part that earns its keep on a public entrance, since vandalism resets by hand rather than turning into a service call.
