Von Duprin 608NL-R 26D – Frequently Asked Questions

1) Will the Von Duprin 608NL trim work on any exit device, or only the 88 Series?
The 608NL night latch trim is built for Von Duprin 88 Series exit devices only. If the device on the door is a 98/99, 33A/35A, or another maker's device, this trim won't mount to it. Check the stamping on the device chassis or touchbar end cap before ordering.
2) What's the difference between the Rim Prep and Mortise Prep versions of the 608NL trim?
It comes down to which 88 Series device is on the door. The rim prep version is made for a rim exit device, the mortise prep version for a mortise lock device. The cylinder and tailpiece arrangement differs between the two, so they are not interchangeable. Identify the device type first, then pick the matching prep. Both preps are offered across the same eleven finishes.
3) The 608NL only fits Von Duprin 88 Series devices. What night latch trim do I use on a different manufacturer's exit device?
The Von Duprin 608NL is engineered for Von Duprin 88 Series exit devices, so it is not a drop-in on another maker's chassis. Match the trim to the device family instead: Corbin Russwin VT957ET is a nightlatch escutcheon trim for ED5000 Series devices in stamped or formed stainless steel; Sargent 744 is a Grade 1 night latch trim with freewheeling action and key retracts latch for 8700 and 8900 Series surface vertical rod and mortise devices; Design Hardware 2P-03NL is a Grade 1 pull trim with cylinder hole for 1000R and 2000R devices; and Accentra 121NL is a nightlatch exit device trim.
4) We are adding card access. Is there an electrified trim I should use instead of the 608NL?
The Von Duprin 608NL is a mechanical night latch trim operated by key, with no electrical function. For access control, Command Access offers electrified exit trims with 12V/24V operation and fail safe or fail secure options, including the 230L built for Von Duprin V96/36/23 Series devices, plus the ET15, ET25, and ET26 series, the ET26 being Grade 1 with a field reversible design. Dormakaba also offers keypad-operated exit trim such as the E-Plex 201U and the PowerPlex P201U for rim, mortise, and SVR devices.
5) What is the closest night latch pull trim to the Von Duprin 608NL if I need a lever instead of a flat pull?
The Von Duprin 608NL is a night latch function trim with a narrow flat pull grip, non-handed, Grade 1 heavy duty. If the opening calls for a lever rather than a pull, the Sargent 704ET is a night latch lever exit device trim, Grade 1 heavy duty, with field reversible operation, and the Sargent 704-ETL in the PE Series is a night latch lever trim with key retract function, also Grade 1 heavy duty. Both put a lever in the user's hand where the 608NL gives a flat grip pull.
6) What night latch pull trim should I spec if I need Grade 1 but the door has a Design Hardware or Dexter device?
The Von Duprin 608NL is Grade 1 heavy duty and is matched to Von Duprin 88 Series devices. For a Design Hardware 1000R or 2000R device, the Design Hardware 2P-03NL is a Grade 1 pull trim with cylinder hole in night latch function. For a Dexter device, the ED1500T-PULL-NC is a Grade 1 nightlatch function trim with a raised lip pull plate. All three keep the pull-style outside grip with a key cylinder.
7) How does a night latch exit trim actually operate on an exterior door?
Night latch means the outside pull grip is fixed, and a key in the cylinder retracts the latch to let someone in. From the inside, the push bar always gives free egress, key or no key. It's the usual choice for a back door or after-hours entrance where staff need keyed access but the door stays locked to the public.
8) Do I need to specify left or right hand when ordering the 608NL?
No handing to specify. The 608NL is non-handed, so one part number covers left and right hand openings. That makes it simpler to stock a spare for a building running multiple 88 Series doors.
9) How far does the 608NL pull grip stick out from the door face?
Projection is 2 1/6 inches off the door. Worth checking against anything in the swing path, a wall, an adjacent door leaf, or a gate, and against the 3/16 inch (5 mm) plate thickness if you're matching an existing trim footprint.
10) Is this exit trim rated for a high traffic commercial entrance?
Grade 1, heavy duty, and specified as a commercial product. That's the top ANSI/BHMA durability tier, which is what you want on a school, hospital, or retail entrance seeing constant use.
11) Should I use a pull grip night latch trim or a lever trim on my exit device?
A flat pull grip like the 608NL carries has no moving handle, so there's less to break and nothing to lever on, which is why it's common on service and rear entrances. Go to a lever when the opening needs ADA-style operation or a function other than night latch. Lever options in the same category include the Sargent 704ET night latch lever and, for other functions, storeroom or classroom trims such as the Falcon 510L classroom lever or the Design Hardware KIL storeroom trim.
12) Does the 608NL trim come with a cylinder?
Plan on supplying the cylinder separately. Night latch trim is keyed by the cylinder you install in it, so order a mortise cylinder in the keyway and keying your building already runs. That's also how you get this door onto the same master key system as the rest of the site.
13) Is a storeroom or classroom lever trim a substitute for the Von Duprin 608NL?
No, they are different functions even though they mount on the same side of the door. The 608NL is night latch: the key retracts the latch for momentary entry and the grip does not operate the device on its own. A storeroom trim such as Design Hardware KIL Storeroom or Tell EDELT80, or a classroom trim such as Falcon 510L or Accentra 446F, uses a lever that stays fixed or is released by key depending on function and gives a different outside-operation behavior. Order by the function on the door schedule, not by appearance.
14) My door is a narrow aluminum stile. Does the 608NL suit it, and what else should I look at?
The Von Duprin 608NL uses a narrow 3/16 inch thick profile with a flat pull grip and a 2 1/6 inch projection, which is the low-profile shape typically chosen for slim stiles, and it is built for Von Duprin 88 Series devices. If your device is not an 88 Series, BEST Precision offers narrow stile trim for its 2000 Series devices: the 2001 exit only pull trim with cover plate and the 2901 narrow stile exit only lever trim. Those are exit only, so confirm whether the opening needs keyed re-entry before substituting.
15) Von Duprin 608NL versus Dormakaba YR03R - what is the difference?
Both are night latch function outside trim for exit devices. The Von Duprin 608NL is a non-handed narrow flat pull grip trim, Grade 1 heavy duty, built for Von Duprin 88 Series devices, and is offered in rim prep and mortise prep versions. The Dorma YR03R is a wide stile escutcheon with an R lever, nightlatch function, supplied less cylinder. The decision comes down to pull grip against lever and which device family is on the door.
16) Is a passage function exit trim interchangeable with the 608NL?
No. The Von Duprin 608NL is a night latch trim that requires a key to retract the latch from outside. Passage function trim always allows outside entry with no key: examples include the Corbin Russwin 3310AET for ED300 Series, the x810ET for ED4000 Series, the x910ET heavy-duty trim for ED5200S, ED5200, ED5400 and ED5800 Series, and the Arrow SRX01 Sierra lever with rose. Use passage trim only where the opening is not meant to be secured from the outside.
17) Which finishes does the Von Duprin 608NL come in for matching the rest of my door hardware?
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/US32 bright stainless, 643E aged bronze, and 693/SPBLK black painted. Satin chrome 626 is the usual match for commercial openings already running aluminum and stainless hardware.
18) Would a blank escutcheon or dummy trim work in place of the 608NL?
Only if the opening is meant to have no outside operation at all. The Von Duprin 608NL is a night latch trim, keyed from outside with free egress inside. A blank or dummy trim covers the device prep without any entry function: the Falcon 212L is a blank escutcheon lever trim for 20 Series devices, and the Detex 02BN is a dummy S-lever trim with blank escutcheon for Value Series devices. Neither retracts the latch.
19) Is there a thumbpiece alternative to the 608NL flat pull grip?
Yes, if you prefer a thumbpiece-operated outside trim to a flat grip pull. The Von Duprin 608NL uses a narrow flat pull grip with a 2 1/6 inch projection. Tell EDTHP53 is a thumbpiece exit device trim in keyed entry function for doors 1-3/8 to 1-3/4 inch thick, and the Dexter ED1000T-CLRM-TP-NC is a Grade 1 classroom trim combining thumbpiece, pull plate, and cylinder, supplied less cylinder. Confirm the device family before ordering either.
