Sargent NB8746E 10BE – Frequently Asked Questions

1) Does the Sargent NB8746 work on a door thicker than 1-3/4 inches?
Standard build covers wood or metal doors 1-3/4 inches thick. For doors over 1-3/4 inches up to 2-1/4 inches, you have to add the 31- prefix when ordering; the standard device will not make up the extra thickness.
2) Do I have to specify handing on the Sargent NB8746?
Yes, handing is a required choice and the device is built to it. Options are RHR (right hand reverse) and LHR (left hand reverse), which are the two hands that apply to an outswinging exit door. Get it wrong and the device will not work on the opening. If you need a non-handed wide stile mortise device, the Von Duprin 9875 and 8875 are listed as non-handed.
3) What does storeroom function mean on this exit device, and is the lever always locked?
Storeroom function on the NB8746 means the outside lever is always locked; entry is by key only, and the key retracts the latch without unlocking the lever. Free egress from the inside is always available through the push rail. The freewheeling ET trim lets the outside lever rotate without load when locked, so someone yanking on it does not damage the mechanism, which is why it holds up on high traffic openings.
4) Do I get the lever trim with the Sargent NB8746, or is that ordered separately?
Trim is a selection you make on the order. ET trim is offered in eight lever designs (A, B, E, F, J, L, P and W), or you can take the device only with no outside trim. Remember the stile rule: with ET trim you need 4-1/2 inches of stile, without it 3-1/2 inches. Ordering device only also means no outside key access, so for storeroom operation you want the trim.
5) I have an aluminum narrow stile door - can I use the Sargent NB8746?
No. The NB8746 is a wide stile device requiring 4-1/2 inch minimum stile with trim and 3-1/2 inch minimum without trim. For narrow stile aluminum doors, the Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device built for aluminum doors, and the Von Duprin 5575-3ft is a Grade 1 narrow stile crossbar mortise exit device for 1-3/4 inch doors that is field reversible.
6) Which mortise exit device should I specify for a fire-rated opening instead of the Sargent NB8746?
Two peers are explicitly fire-rated: the Adams Rite 3300 Series is a fire-rated Grade 1 wide stile mortise exit device for wood and hollow metal doors, and the Corbin Russwin ED5600AL is a Grade 1 3 hour fire rated wide stile mortise device for 1-3/4 inch doors, used exit only or with classroom or passage lever trim ordered separately. By contrast the Adams Rite 8300, Von Duprin 8875, 9875 and 9475/9575 are listed as not fire rated. The Sargent NB8746 NB8700 Series is stated as suitable for both rated and non-rated openings.
7) What is the closest Von Duprin equivalent to the Sargent NB8746 for a wide stile door?
The Von Duprin 9875-3FT is the nearest wide stile counterpart. It is a 3 ft smooth case wide stile mortise exit device, Grade 1, non-handed, for doors 1-3/4 inch thick. The Sargent NB8746 is also Grade 1 and wide stile, with storeroom function and freewheeling ET lever trim, and it is ordered handed as RHR or LHR. One practical difference: the 9875 is listed as not wood door compatible, while the NB8746 is specified for wood or metal doors 1-3/4 inch thick.
8) Which of these mortise exit devices work on wood doors?
The Sargent NB8746 is specified for wood or metal doors 1-3/4 inch thick, with a 31- prefix for doors over 1-3/4 inch up to 2-1/4 inch. The Adams Rite 3300 and 8300 Series are both described for wood and hollow metal doors. The Von Duprin 8875-3FT and 9875-3FT and the Detex 30 Series are listed as not wood door compatible, so rule those out on a wood opening.
9) Is a surface vertical rod device the right choice, or should I use a rim device?
The NB8746 is a top latch surface vertical rod device, so it latches vertically at the head rather than into a strike on the frame jamb. That is what you want on a pair of doors with no center mullion, and on doors where a rim strike on the jamb is not workable. If you have a single door in a frame with a solid jamb, a rim device is simpler to prep and install. Rods are surface mounted here, so no concealed routing in the door is required.
10) Is the Sargent NB8746 Grade 1, and what does that get me on a high traffic door?
Grade 1 is the top ANSI/BHMA commercial durability tier, and the NB8746 carries it. For a school corridor, hospital, or warehouse door cycling all day, that is the grade specifications call for. Every wide stile mortise peer worth comparing it against is also Grade 1, including the Corbin Russwin ED5600AL, Falcon 25-M-EO, Detex 30 Series and Von Duprin 9875, so the decision between them comes down to fire rating, wood door compatibility and function rather than grade.
11) Can I dog the Sargent NB8746 open during business hours?
Dogging is available as an electric option rather than something you assume is included: order 58 for electric dogging, or 56 for remote dogging with latch retraction if you want it tied to an access control schedule. Keep in mind that on a fire rated opening dogging is not permitted, so specify accordingly for rated doors.
12) The opening does not need lever trim - what is a simpler alternative to the Sargent NB8746?
If the door only needs free egress with no outside access, an exit-only device skips the trim entirely. The Falcon 25-M-EO is a Grade 1 wide stile mortise exit device in exit-only function for 1-3/4 inch doors in a 36 inch, 3 ft size, and the BEST Precision 2301 is a mortise exit device in exit only with heavy wrought construction. The Detex 30 Series Advantex is another Grade 1 wide stile device-only option, though it is not wood door compatible. The NB8746 carries storeroom function with freewheeling ET trim, so choose it when you need keyed outside entry.
13) Is the Von Duprin 8875 a drop-in substitute for the Sargent NB8746?
They are not interchangeable at the door. Both are Grade 1 wide stile mortise exit devices, but the Von Duprin 8875-3FT is a crossbar device, non-handed, for 1-3/4 inch doors and listed as not wood door compatible. The Sargent NB8746 is a push rail surface vertical rod device ordered handed RHR or LHR and specified for wood or metal doors. Mounting prep and the look of the finished door both differ, so treat the 8875 as a different device rather than a direct swap.
14) If I need lever trim on the outside, which devices include it and which do not?
The Sargent NB8746 is offered with ET trim in A, B, E, F, J, L, P and W lever styles, or as exit device only. The Corbin Russwin ED5600AL is sold exit only or for use with classroom or passage lever trim that is not included, so the trim is a separate line. The Falcon 25-M-EO and BEST Precision 2301 are exit-only devices with no outside lever. Confirm the lever style before ordering so the finish and design match the rest of the openings.
15) What finishes does the Sargent NB8746 come in so I can match the rest of my openings?
Twelve finishes: 03 bright brass and 04 satin brass (clear coated), 09 bright bronze and 10 satin bronze (clear coated), 10B oil rubbed dark oxidized satin bronze, 10BE and 10BL dark oxidized satin bronze, 20D dark statuary bronze lacquered, 32 bright stainless and 32D satin stainless, plus BSP black suede and WSP white suede powder coat. For most commercial corridors 32D satin stainless is the standard match; the powder coats are the ones to pick when you are matching painted aluminum or dark frames.
16) Is the Sargent NB8746 a crossbar or a push pad device?
The NB8746 uses a push rail, not a crossbar, and the rail length is matched to the door width you order. If your building is standardized on crossbar devices and you want to keep the look consistent, the Von Duprin 8875 (wide stile, 36 inch) and the 5575 (narrow stile) are crossbar mortise devices. The Von Duprin 9475/9575 Impact Series uses a recessed push pad.
17) What wide stile alternative holds up best to abuse in a high-traffic corridor?
The Von Duprin 9475/9575 Impact Series is a Grade 1 wide stile mortise exit device with a recessed push pad, which keeps the actuator out of the line of carts and equipment. The Detex 30 Series Advantex is a Grade 1 wide stile mortise device rated for device-only use on non-wood doors. The Sargent NB8746 is a Grade 1 NB8700 Series device offered in 32, 36, 42 and 48 inch sizes with storeroom function, so it is the pick when the corridor door also needs keyed outside entry.
