Sargent NB8713E 10BE – Frequently Asked Questions

1) Will the Sargent NB8713 exit device fit a 1-3/4 inch door, and what if my doors are thicker?
1-3/4 inch (44mm) wood or metal doors are the standard build for the NB8713. For openings thicker than 1-3/4 inch up to 2-1/4 inch, the device has to be ordered with the 31- prefix. That prefix is specified at order time, so thicker doors need to be identified before the order goes in rather than corrected on site.
2) What stile width do I need for a Sargent NB8713 surface vertical rod device?
With lever trim, you need a 4-1/2 inch (114mm) minimum stile. Device only, with no trim on the outside, the minimum drops to 3-1/2 inch. That makes it a wide stile device, so a narrow stile aluminum storefront door will not take it. For narrow stile aluminum, look at the Adams Rite 8400 Series mortise exit device instead.
3) How do I pick the right rail length for my door width on the Sargent NB8713?
Rail selection runs by door width: E Rail covers 24 to 32 inches, F Rail 33 to 36 inches, J Rail 37 to 42 inches, and G Rail 43 to 48 inches. Sizes are ordered as 32, 36, 42, and 48 inch, and at those four standard widths the rail installs with no cutting. Odd widths inside each range are handled by trimming within that same rail size.
4) Do I have to specify handing when ordering the Sargent NB8713?
Yes, handing is required. The NB8713 is built either RHR (right hand reverse) or LHR (left hand reverse), and it is not field reversible the way some crossbar devices are. Stand outside the door: if it swings toward you and the hinges are on the right, it is RHR. Von Duprin's 8875 and 9875 wide stile mortise devices are non-handed if you need stock that covers either hand.
5) Can I use the Sargent NB8713 on a pair of doors without a mullion?
Surface vertical rod is the configuration for pairs without a center mullion, because each leaf latches into the frame at the head rather than into a strike on the other leaf. The NB8713 is a top latch surface vertical rod device, so it latches at the head. Order one device per leaf and confirm the hand of each.
6) What is the closest Grade 1 wide stile mortise exit device to the Sargent NB8713 if I need classroom lever trim?
The Corbin Russwin ED5600AL is the nearest match on function. It is a Grade 1 mortise exit device for wide stile doors that accepts passage or classroom lever trim, with a 1-3/4 inch door thickness, and it carries a 3 hour fire rating. The Sargent NB8713 is a Grade 1 classroom function wide stile device that can be ordered with ET lever trim in A, B, E, F, J, L, P or W lever styles or as device only. The main practical difference is that the ED5600AL lever trim is not included and must be specified separately, while the NB8713 trim option is chosen as part of the device order.
7) Can I use the Sargent NB8713 on a narrow stile aluminum storefront door?
No. The NB8713 is a wide stile device and needs a 4-1/2 inch minimum stile with trim, or 3-1/2 inch without trim. A narrow stile aluminum storefront will not give you that. For those openings the Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device built for aluminum doors, and the Von Duprin 5575 is a Grade 1 narrow stile crossbar mortise device for 1-3/4 inch doors that is field reversible. Measure the stile face before ordering either way.
8) I only need free egress with no outside trim - is there a simpler device than the Sargent NB8713?
Yes. If nobody needs to key back in from the outside, an exit only device removes the lever trim and cylinder entirely. The Falcon 25-M-EO is a Grade 1 wide stile mortise exit device built as exit only for 1-3/4 inch doors in a 36 inch, 3 foot size, and the BEST Precision 2301 is a mortise exit device in exit only configuration with heavy wrought construction. The Detex 30 Series Advantex is another Grade 1 wide stile mortise device supplied as device only. The Sargent NB8713 is a classroom function device, which exists specifically so the outside lever can be locked and unlocked by key - if that is not part of the opening, the exit only devices do the same egress job with less to specify.
9) Does the Sargent NB8713 work on a fire rated opening, or do I need a different device?
The NB8713 is a surface vertical rod device with a top latch, ordered for classroom function on wood or metal doors 1-3/4 inch thick. If your drawing calls for a labeled fire exit mortise device, the Corbin Russwin ED5600AL is a Grade 1 3 hour fire rated mortise exit device for wide stile 1-3/4 inch doors, and the Adams Rite 3300 Series is a fire rated Grade 1 wide stile mortise exit device for wood and hollow metal doors. Note that several common wide stile mortise devices are not fire rated at all, including the Adams Rite 8300, Von Duprin 8875, 9875 and 9475/9575 - check the label requirement before you pick.
10) My doors are wood - which wide stile mortise exit devices actually go on wood?
The Sargent NB8713 is built for wood or metal doors 1-3/4 inch thick, with an over 1-3/4 inch to 2-1/4 inch option when ordered with the 31- prefix. Among the wide stile alternatives, the Adams Rite 3300 and 8300 Series are listed for wood and hollow metal doors, and the Falcon 25-M-EO is a wide stile mortise device for 1-3/4 inch doors. Rule out the Von Duprin 8875 and 9875 and the Detex 30 Series for wood openings - those are listed as not wood door compatible.
11) What does classroom function mean on the Sargent NB8713 and is it right for a school door?
Classroom function means the outside lever is locked or unlocked by key, while the push rail always retracts the latch for free egress from inside. Nobody gets locked in, and staff control entry from the corridor side. That is the standard arrangement for classroom and controlled-access commercial openings. If you want an exit-only door with no outside trim at all, order it without trim rather than using a classroom device.
12) What lever trim options come with the Sargent NB8713?
ET trim is offered in eight lever designs: A, B, E, F, J, L, P and W. You can also order the device by itself with no outside trim. Remember the stile rule, with any ET trim on the door you need 4-1/2 inches of stile, not 3-1/2.
13) I need a fire rated mortise exit device for a wood door. Is the Sargent NB8713 the right choice?
For a stated fire rated mortise exit device on wood or hollow metal, the Adams Rite 3300 Series is the wide stile Grade 1 option carrying a fire rating in our records. Bear in mind that a surface vertical rod device on a fire door normally cannot be dogged, so if the opening is rated, avoid the dogging and electric dogging options and confirm the label requirements for that door.
14) What is the difference between the Sargent NB8713 and the Von Duprin 8875 or 9875 wide stile mortise devices?
All three are Grade 1 wide stile mortise exit devices. The Von Duprin 8875 is a crossbar device in a 36 inch, 3 foot size, non-handed and not fire rated; the 9875 is a smooth case 3 foot device, also non-handed and not fire rated. The Sargent NB8713 is a push rail style surface vertical rod device with a top latch that is ordered by hand, RHR or LHR, in 32, 36, 42 and 48 inch sizes with classroom function. If the opening is a pair of doors needing vertical rod latching, the NB8713 addresses that; if it is a single leaf and a crossbar look is acceptable, the Von Duprin devices are the non-handed route.
15) Is there a wide stile mortise exit device better suited to an abuse-prone opening than the Sargent NB8713?
For high-abuse traffic, the Von Duprin 9475/9575 Impact Series is a Grade 1 wide stile mortise lock exit device with a recessed push pad, which keeps the pad out of the line of carts and equipment. The Detex 30 Series Advantex is a Grade 1 wide stile mortise device as well, though it is listed as device only and not wood door compatible. The Sargent NB8713 is Grade 1 for heavy duty commercial use and is the choice when you need classroom function with keyed lever trim, which the exit only devices do not provide.
16) What finishes does the Sargent NB8713 come in for matching existing hardware in a building?
Twelve finishes are offered: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE, 10BL clear coated, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, plus BSP black suede powder coat and WSP white suede powder coat. For standardizing across a facility, 32D satin stainless is the usual commercial default and the powder coats are the route when doors need to match a painted frame color.
