Von Duprin 996K-NL-R/V 26D – Frequently Asked Questions

1) What does the night latch function on the Von Duprin 996K-NL knob trim actually do at the door?
With the K-NL (night latch/storeroom) setup, the key retracts the latch to let someone in from the outside. The knob itself stays rigid, so it never operates the latch. The door is always locked from outside and always free to exit from the inside through the push bar. That is the right function for storerooms, mechanical rooms, and any opening where you want key-only entry.
2) Which Von Duprin exit devices does the 996K-NL knob trim work with?
The 996K-NL is built for Von Duprin 98 and 99 Series exit devices. When you order it you pick the device type it is going onto: one version is for mortise devices, the other covers rim, surface vertical rod, and concealed vertical rod devices. Those are not interchangeable, so match the trim to the device you have on the door.
3) Do I have to specify handing when I order the 996K-NL knob trim?
No handing to call out. The 996K-NL is non-handed, so the same part goes on a left- or right-hand opening. What you do have to specify is the device type (mortise, or rim/SVR/CVR) and the finish.
4) Can I use the 996K-NL knob trim on a fire rated door?
Yes. The 996K trim line meets ANSI/UL 10C and CAN/ULC-S104 in fire rated configurations, along with ANSI/UL 305 and CAN/ULC-S132 for panic hardware. It is also certified to ANSI/BHMA A156.3 2014 Grade 1. Note that on a fire rated opening the trim has to be mounted on a fire labeled 98/99 device, and no dogging is permitted on fire exit hardware.
5) Should I use knob trim or lever trim on an exit device?
Knob trim like the 996K-NL is a fixed-grip pull that the key operates. Lever trim is what most jurisdictions want on an accessible egress route, since a lever needs no tight grasping or twisting. If accessibility is driving the spec, look at a lever nightlatch trim instead, such as the Sargent 704ET or 704-ETL night latch lever trim, or the Corbin Russwin VT957ET nightlatch escutcheon. Where a knob is acceptable, the 996K-NL gives you the same key-retracts-latch operation in a Grade 1 heavy duty trim.
6) What is the equivalent night latch exit trim if I am not on a Von Duprin device?
Trim is device-specific, so match the brand and series of the exit device already on the door. For Sargent devices, the 704ET or the 704-ETL is the Grade 1 night latch lever trim; the 744 covers Sargent 8700 and 8900 surface vertical rod and mortise devices with a key-retracts-latch freewheeling trim. On Corbin Russwin ED5000 devices, the VT957ET nightlatch escutcheon is the counterpart. For Design Hardware 1000 and 2000 series devices, the KIL storeroom trim is the Grade 1 storeroom option. The 996K-NL fits Von Duprin 98/99 only.
7) What is the closest night latch exit device trim to the Von Duprin 996K-NL if I need a lever instead of a knob?
The 996K-NL is a knob trim with Night Latch (Storeroom) function, so the key retracts the latch while the knob stays rigid. If the opening calls for a lever instead, the Sargent 704ET is a night latch lever exit device trim, Grade 1 and heavy duty with field reversible operation, and the Sargent 704-ETL is a night latch lever trim with key retract function for PE Series devices, also Grade 1 heavy duty. Both keep the key-retracts-latch behavior and change only the handle style. Confirm the lever trim matches the exit device family already on the door.
8) Is the Accentra 121NL the same thing as the Von Duprin 996K-NL?
They share the night latch idea but are not interchangeable. The 996K-NL is a knob night latch trim certified to ANSI/BHMA A156.3 Grade 1 and fitted to Von Duprin 98 and 99 Series devices, with fire-rated configurations compliant to ANSI/UL 10C. The Accentra 121NL is an exit device nightlatch trim listed with a fire rating of No. On a fire-rated opening, that distinction decides the order.
9) How far does the 996K knob stick out from the door face?
Projection is 3-1/4 inches from the door. That matters if the opening sits next to a wall return, a column, or a second leaf, and on any door where a knob could catch a passing cart. Measure your side clearance before you commit to knob trim.
10) I need classroom function instead of storeroom on my 98/99 device. Do I have to replace the whole trim?
Stay in the 996 family. The 996 trim line covers four functions on the same platform: classroom (K), storeroom/night latch (K-NL), dummy (K-DT), and passage (K-BE). Because the 98/99 trim system is modular, a facility can change the trim function later without reworking the device, so the -NL is not a dead end if the room's use changes.
11) Is the 996K-NL heavy duty enough for a school or hospital corridor?
It is rated heavy duty and designated commercial, certified to ANSI/BHMA A156.3 2014 Grade 1, which is the top ANSI grade for exit device hardware. That is the level specified for schools, healthcare, government buildings, and high traffic retail.
12) I want card reader control on the outside of my Von Duprin 98/99 device. Is the 996K-NL the right trim?
No. The 996K-NL is mechanical only, keyed from the outside. For access control you want electrified trim, where the lever or knob is released by 12V or 24V power. Command Access builds electrified exit trim for Von Duprin, including the 230L for V96/36/23 series devices, with fail safe and fail secure options. Pick fail safe or fail secure based on whether the opening must release or must stay locked when power drops.
13) Does the 996K-NL knob trim come with a cylinder?
Plan on supplying the cylinder separately. The night latch function is driven by a key from the outside, so the trim needs a cylinder keyed into your system, and in a facility that means matching the keyway and keying of the other openings before the trim goes on the door.
14) I need a storeroom function exit trim but the door has a Design Hardware 1000 or 2000 series device. What do I use instead of the 996K-NL?
The 996K-NL matches Von Duprin 98 and 99 Series devices only. For Design Hardware 1000 and 2000 Series devices, the Design Hardware KIL Storeroom trim is a Grade 1 storeroom function exit trim with a flat lever and Schlage C keyway. If you need entry function on that same device family instead of storeroom, the Design Hardware KIL Entry trim covers it, also Grade 1.
15) Can I swap a passage function exit trim for the Von Duprin 996K-NL?
They behave differently. The 996K-NL is a night latch (storeroom) trim, so the knob does not retract the latch and a key is required from the outside. Passage trims such as the Arrow SRX01 Sierra lever with rose, the Corbin Russwin 3310AET for ED3000 Series, and the Corbin Russwin x910ET for ED5200/ED5400/ED5800 Series are passage function, meaning the handle retracts the latch with no key. Use passage only where the opening does not need to stay secured from outside.
16) What night latch trim works on a Corbin Russwin ED5000 device rather than a Von Duprin 98/99?
The 996K-NL is specific to Von Duprin 98 and 99 Series devices. For Corbin Russwin ED5000 Series devices, the VT957ET is a nightlatch escutcheon trim in stamped or formed stainless steel. The Dorma YR03R is another night latch option, a wide stile escutcheon lever trim supplied less cylinder.
17) If I want classroom function instead of night latch on my exit device, what are my options?
Within the 996 knob trim family, classroom is the K function while the 996K-NL is the K-NL storeroom/night latch version. Across other device brands, the Falcon 510L is a heavy duty classroom function lever trim for 24/25 Series devices, the Accentra 446F is a Grade 1 classroom function trim with an Augusta lever, and the Dexter ED1000T-CLRM-TP-NC is a Grade 1 classroom trim with thumbpiece and pull plate, less cylinder.
18) Does a medium duty exit trim substitute for the Von Duprin 996K-NL in a high traffic corridor?
The 996K-NL is rated Heavy Duty and certified Grade 1 for commercial use. Falcon's 179L lever control trim for 1790 Series and the Falcon 212L escutcheon lever trim for 20 Series are both listed as Medium Duty. If you want to stay at heavy duty on another device platform, the Falcon 510L is Heavy Duty for 24/25 Series devices and the Pamex E9000 is a Grade 1 heavy duty storeroom L3 lever trim covering 1-3/8 inch to 2 inch doors.
19) What looks like a substitute for the 996K-NL but will not secure the door?
Dummy and blank escutcheon trims mount in similar locations but have no keyed control. The Detex 02BN is a dummy S-lever trim with a blank escutcheon for Value Series devices, and the Falcon 212L is a blank escutcheon lever trim for 20 Series. The 996 family also includes a Dummy (K-DT) and Passage (K-BE) version alongside the K-NL night latch. Only the night latch version gives you key-retracts-latch with a rigid outside knob.
20) What finishes does the Von Duprin 996K-NL come in?
Eleven finishes, and the same eleven are offered on both the mortise version and the rim/vertical rod version: 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, 643E aged bronze, 693/SPBLK black painted, and 695/SP313 dark bronze. 626 satin chrome is the usual match for existing commercial openings.
