Sargent NB8710E 32D – Frequently Asked Questions

1) What does the dummy / exit only function on the NB8710 actually do?
Exit only means there is no outside operation at all. Push the pad from inside and the doors release; from the outside there is no lever, no cylinder, no way in. Use it on stair discharge, rear service doors, and egress-only openings. If you need people to come back in through the door, you want a device that accepts lever trim instead, such as the Corbin Russwin ED5600AL, which takes passage or classroom lever trim.
2) Do I need a mullion to use the NB8710 on a pair of doors?
No. It is a surface vertical rod device, so it latches into the frame at the head rather than into a center mullion. That lets you hang it on both leaves of a pair and keep the full clear opening with nothing standing in the middle. A rim device on that same pair would need a removable mullion between the leaves.
3) Which rail length do I order for my door width on the Sargent NB8700 device?
Match the rail to the door leaf width: E Rail covers 24 to 32 inch doors, F Rail 33 to 36 inch, J Rail 37 to 42 inch, and G Rail 43 to 48 inch. Standard sizes need no cutting. The orderable sizes run 32, 36, 42 and 48 inches.
4) Is handing required when ordering the Sargent NB8710?
Yes, it is handed and you must pick one when you order: RHR (right hand reverse) or LHR (left hand reverse). Exit devices are always reverse bevel since the door swings out in the direction of egress, so stand outside the opening to call it. If you would rather not track handing across a building, the Von Duprin 8875 and 9875 wide stile mortise devices are non-handed.
5) Will the NB8710 work on a wood door, or is it hollow metal only?
Both. The NB8700 Series mounts on wood or metal doors at 1-3/4 inches thick. That matters if you are standardizing a building with mixed leaves, because several wide stile mortise devices we carry are metal door only, including the Von Duprin 8875, the Von Duprin 9875, and the Detex 30 Series Advantex.
6) What is the closest equivalent to the Sargent NB8710 exit-only device from another manufacturer?
The Falcon 25-M-EO is the nearest straight equivalent: it is a Grade 1 wide stile mortise exit device built for exit only function on 1-3/4 inch doors, matching the NB8710's Grade 1 wide stile exit-only role. The Falcon part is supplied as a 36 inch, 3 foot device, while the Sargent NB8710 covers 32, 36, 42 and 48 inch door widths in one series. BEST Precision 2301 is another exit-only mortise device, built with heavy wrought construction.
7) My opening is a narrow stile aluminum storefront door - what should I use instead of the Sargent NB8710?
The NB8710 is a wide stile device and calls for a 4-1/2 inch minimum stile with trim, so it does not suit a narrow aluminum stile. For narrow stile aluminum doors, the Adams Rite 8400 is a Grade 1 life-safety narrow stile mortise exit device built for aluminum doors. The Von Duprin 5575 is also a narrow stile Grade 1 mortise exit device, in a crossbar style and field reversible.
8) I need a lever trim that unlocks from outside, not an exit-only device like the NB8710 - what is the alternative?
The NB8710 is a dummy/exit only function, so there is no outside operation. If the opening needs entry from the pull side, the Corbin Russwin ED5600AL is a Grade 1 mortise exit device that accepts passage or classroom lever trim (trim sold separately). Within the Sargent NB8700 line itself, ET trim levers in A, B, E, F, J, L, P and W styles are the trim families offered alongside the device.
9) Can the NB8710 go on a fire rated opening?
The NB8700 Series is made for both rated and non-rated openings. Note the exit only version has no outside trim, which suits a stair door on the discharge side. If your spec calls out a device the manufacturer lists as fire rated in its own right, the Adams Rite 3300 Series mortise exit device is carried as fire rated for wood and hollow metal doors.
10) If I order ET lever trim with the Sargent NB8700 device, which lever styles are available?
ET trim comes with A, B, E, F, J, L, P or W lever designs, or you can order the device with no trim at all for straight exit only use. Remember the trim raises the stile requirement to 4-1/2 inches minimum, versus 3-1/2 inches for the bare device.
11) Is the Sargent NB8710 Grade 1, and what else is Grade 1 in a wide stile mortise exit device?
Grade 1, which is the heaviest commercial duty classification and what most institutional specs call for. Grade 1 wide stile mortise alternatives we carry include the Corbin Russwin ED5600AL, the Falcon 25-M-EO exit only, the Detex 30 Series Advantex, the Adams Rite 8300 Series, and the Von Duprin 9875.
12) We are standardizing a building on one exit device family - how do the wide stile Grade 1 mortise options line up?
All of the main wide stile choices carry a Grade 1 rating: the Sargent NB8710, the Adams Rite 3300 and 8300, the Corbin Russwin ED5600AL, the Falcon 25-M-EO, the Detex 30, and the Von Duprin 8875, 9875 and 9475/9575. The separators are opening type and function rather than grade: the Adams Rite 3300 and Corbin ED5600AL are fire rated, the Adams Rite 8300 and the Von Duprin devices are listed non fire rated, and the Falcon 25-M-EO, Detex 30 and Sargent NB8710 are exit only devices. The Sargent NB8700 line adds twelve finishes and four device lengths for matching across a facility.
13) Is a Von Duprin 8875 or 9875 a drop-in substitute for the Sargent NB8710?
Not a drop-in. Both Von Duprin parts are Grade 1 wide stile mortise exit devices for 1-3/4 inch doors and are non-handed, whereas the Sargent NB8710 is ordered as RHR or LHR. The 8875 uses a crossbar and the 9875 a smooth case push rail, and both are supplied as 36 inch, 3 foot devices; the NB8710 is a surface vertical rod device covering 32 through 48 inch door widths. Door prep and rod hardware differ, so treat them as a specification change rather than a direct swap.
14) What finishes does the Sargent NB8700 exit device come in to match my other 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 and WSP white suede powder coat. 32D satin stainless is the usual choice for matching commercial hardware already in a building.
