Not every door needs a fire-rated exit device

Specifying panic hardware for a rated stairwell or a fire-separation door means paying for a fire rating, because code requires it there. But a lot of exit devices go on doors that will never see a fire inspector's tape measure: a storage room with occupant load requirements, a warehouse man-door, a non-rated back exit off a retail floor. Speccing full fire-rated hardware on those doors isn't wrong, exactly, but it's paying for a rating the door doesn't need and doesn't use.

The 88 Series: Von Duprin's non-fire-rated pushpad line

The Von Duprin 88 Series is a narrow stile pushpad rim exit device, built specifically for aluminum storefront and glass doors that need code-compliant panic hardware without the fire-rated construction and price of the 99 or 9927 lines. It's the same manufacturer, the same general engineering pedigree, aimed at the doors that don't carry a fire-separation requirement.

Pushpad, not crossbar — and it fits a narrower stile

Where the older-style Von Duprin devices use a full-width crossbar, the 88 Series uses a pushpad design that sits closer to the door surface for a cleaner, lower-profile look. That's a real functional difference, not just cosmetic: the pushpad geometry lets the 88 Series fit door stiles as narrow as 2 inches, which is tight even by narrow-stile aluminum storefront standards. If you've got a slim-frame glass door where a bulkier device physically won't clear the stile, the 88 Series is built for exactly that constraint.

Exit Only or Night Latch: match the function to what the door needs

The 88EO-US26D is the Exit Only function: push bar operation from the inside, no outside trim, free egress at all times, no cylinder required. This is the right pick on a door that only ever needs to let people out from the secure side, like a warehouse man-door or a code-required exit off a back room.

The 88NL-US26D adds a night latch function with the 880NL trim, letting authorized staff enter from the outside with a key while the door still provides free egress from the inside at all times. That's the better fit on a retail back door or an office entrance where staff need their own way in after hours, but the panic function itself can never be defeated from the inside.

Handed hardware — don't order this one blind

The 88 Series is a handed device, meaning it's built specifically for a left-hand-reverse or right-hand-reverse door swing, and the two aren't interchangeable in the field the way some hardware is. Verify LHR or RHR before ordering. Getting the handing wrong on a narrow stile device is a worse problem than on a wider door, because there's less room to improvise a fix on-site.

UL listed, Grade 1, hex key dogging — the parts that don't get cut for the lower price

Being non-fire-rated doesn't mean the 88 Series skips certification. It's UL listed for panic exit hardware and carries the same ANSI/BHMA A156.3 Grade 1 certification as Von Duprin's heavier fire-rated lines, with hex key dogging standard for holding the latch retracted during business hours if the door needs to stay open for traffic. The savings versus a fire-rated device comes from not building in the fire-rated components a rated door requires, not from cutting the exit device's own grade or listing.

Dummy trim: covering the second leaf of a pair without a second active device

On a pair of doors where only one leaf needs to be an active exit, Von Duprin builds an 880DT dummy trim option into the 88 Series line for the inactive leaf. That covers the appearance and push surface of a matching device on the second door without paying for a second fully functional exit mechanism the opening doesn't need. It's a detail worth raising at quote time on any storefront pair where only one door actually gets used for daily traffic.

Where the 88 Series doesn't belong

Do not spec this line on a rated stairwell, a fire-separation corridor door, or anywhere the building code or the door's own label calls for fire-rated hardware. A non-fire-rated exit device on a door that requires one is a code violation regardless of how well the hardware otherwise performs, and it's the kind of mistake an inspector catches immediately by checking the door label against the installed hardware. Confirm the door's fire rating, or lack of one, before specifying anything in this line.

Pro tip from the counter: keep the EO and NL functions straight when quoting a job with several similar back doors. It's an easy mix-up on a multi-door punch list, and swapping trim after installation costs more time than getting the order right the first time. For the doors that do need a fire rating, see our Von Duprin 99 guide; for a budget comparison against another maker's economical exit device, our Falcon 25 guide covers that ground.

Common questions

Is the Von Duprin 88 Series fire rated?

No. It's built as a non-fire-rated exit device for doors that don't carry a fire-separation requirement. Do not use it on a rated stairwell or fire door.

What's the narrowest stile the 88 Series fits?

The pushpad design fits door stiles as narrow as 2 inches, which is why it's specified on narrow-stile aluminum storefront and glass doors where bulkier devices won't clear.

What's the difference between the 88EO and the 88NL?

The 88EO is exit-only with no outside trim or cylinder. The 88NL adds a keyed night latch function for outside entry while keeping the panic function always active from the inside.

Is the 88 Series lower grade than Von Duprin's fire-rated lines?

No. It carries the same ANSI/BHMA A156.3 Grade 1 certification and UL listing for panic hardware. The savings comes from not building in fire-rated construction, not from a lower grade.

Do I need to specify handing when ordering?

Yes. This is a handed device, ordered LHR or RHR to match the door swing. Confirm handing before ordering rather than assuming it can be adjusted on-site.
