Sargent 8304E 10BE – Frequently Asked Questions

1) What does the night latch function on the Sargent 8304 exit device actually do?
Night latch means the outside trim is always locked and a key retracts the latch for entry. Push the pad from the inside and you get free egress every time. There is no outside lever operation without the key, which is what you want on an after-hours entrance or a service door where staff carry keys but the public should never be able to pull the door open.
2) Is the Sargent 8304 right for an aluminum storefront door, or do I need a wide stile device?
The 8304 is the narrow stile version of Sargent's 8300 mortise exit devices, so it is built for the slim stiles you find on aluminum storefront and glass front doors. If your opening is a hollow metal or wood door with a full-width stile, a wide stile device is the better fit, such as the Corbin Russwin ED5600AL or the Von Duprin 9875. Check your actual stile before ordering, since a wide stile chassis will not land on a narrow storefront rail.
3) Do I have to specify handing on the Sargent 8304?
Yes, handing is required and there is no field-reversible option. You pick either RHR (right hand reverse) or LHR (left hand reverse). Stand outside the opening: if the door swings toward you and the hinges are on the right, it is RHR. Get this wrong and the device will not mount. If you need a non-handed mortise device, the Von Duprin 5575 narrow stile crossbar device is field reversible.
4) What door widths does the Sargent 8304 cover?
Four device lengths are offered: 32, 36, 42 and 48 inches. Pick the length that matches your door width, not one that overhangs. One caveat on options: the AL alarmed version requires a 36 inch minimum door width, so it cannot be combined with the 32 inch device.
5) Does the Sargent 8304 come with outside trim, or do I order that separately?
Trim is a choice you make on the order. You can take the device on its own (Exit Device Only) or add ET trim with your choice of lever design: A, B, E, F, J, L, P or W. Since the 8304 is night latch function, that outside lever is a dummy pull until the key is used. If you are replacing an existing device and reusing the trim, order the device only.
6) Can I use the Sargent 8304 on a pair of doors without a mullion?
No. A mortise device latches into the frame jamb, so it needs a solid strike point at the lock edge. On a pair of doors that means either an inactive leaf with a strike or a mullion between them. If you need to secure a pair and keep the full opening clear, a surface vertical rod device is the right type instead, since it latches at the head and threshold rather than the jamb.
7) What is the closest narrow stile mortise exit device to the Sargent 8304 from another manufacturer?
For an aluminum or other narrow stile opening, the two closest peers are the Adams Rite 8400 Series narrow stile mortise exit device for aluminum doors and the Von Duprin 5575 narrow stile mortise lock exit device, which is listed at Grade 1, non fire rated, with a 1-3/4 inch door thickness and field reversible handing in the 3 ft size. The Sargent 8304 is a Grade 1 narrow stile mortise device in the 8300 Series with night latch function, ordered RHR or LHR. The Von Duprin 5575 uses a crossbar actuator rather than a push rail, so confirm which look the opening calls for before substituting.
8) I need a fire rated mortise exit device - can I use the Sargent 8304?
The 8304 is a Grade 1 narrow stile mortise device in the 8300 Series. Where the opening requires a fire rated mortise device, the Adams Rite 3300 Series is listed as fire rated Grade 1 for wood and hollow metal doors, and the Corbin Russwin ED5600AL is listed as a Grade 1 3 hour fire rated mortise exit device. Both of those are wide stile devices, so they suit a wood or hollow metal leaf rather than a narrow aluminum stile.
9) My doors are wide stile hollow metal, not narrow stile - what mortise exit device should I use instead of the Sargent 8304?
The 8304 is built for narrow stile openings. For a wide stile hollow metal leaf, the Von Duprin 9875-3FT is a Grade 1 smooth case wide stile mortise device, non-handed, for 1-3/4 inch doors, and the Von Duprin 8875-3FT is the crossbar wide stile equivalent at the same grade and door thickness. The Falcon 25-M-EO is another Grade 1 wide stile mortise device for 1-3/4 inch doors. Note that both Von Duprin devices are listed as not wood door compatible.
10) Is the Adams Rite 8300 Series the same thing as the Sargent 8300 Series?
No - the series numbers match but the products do not. The Adams Rite 8300 Series is a life-safety mortise exit device for wood and hollow metal doors, listed as wide stile, Grade 1, and non fire rated. The Sargent 8300 Series device covered by model 8304 is a narrow stile mortise exit device with night latch function at Grade 1. If your spec calls out an 8300 mortise device, confirm the manufacturer before ordering, since the stile type and door material are different.
11) I need a non-handed mortise exit device - does the Sargent 8304 work or should I choose something else?
The Sargent 8304 is ordered by hand, RHR or LHR, so the handing has to be confirmed at the time of order. If you want to stock one device for either hand, the Von Duprin 9875-3FT and 8875-3FT are both listed as non-handed Grade 1 wide stile mortise devices for 1-3/4 inch doors, and the narrow stile Von Duprin 5575-3ft is listed as field reversible.
12) Is the Sargent 8304 narrow stile exit device Grade 1?
Grade 1 is what the 8304 carries, exceeding ANSI/BHMA Grade 1 requirements for cycle and strength testing. That is the highest commercial rating and the one usually written into institutional and government specs. If you are standardizing a facility, note that most of the mortise exit devices in this class are Grade 1 as well, including the Adams Rite 8400 narrow stile device.
13) What is the difference between a mortise exit device like the Sargent 8304 and a rim device?
A mortise device puts the lock case inside a pocket routed into the door edge, so the latch engages a strike in the frame jamb and the whole assembly sits flush and clean. A rim device bolts to the face of the door and latches into a surface strike. Mortise prep is more work up front and the door has to be machined for it, but you get a concealed lock body and, on the 8304, key access from outside through night latch function. If your doors are not already mortise prepped, expect machining as part of the job.
14) I do not need outside trim - is there a simpler mortise exit device than the Sargent 8304?
If the opening is exit only with no outside operation, the Falcon 25-M-EO is listed as exit only, Grade 1, wide stile for 1-3/4 inch doors, the Detex 30 Series Advantex is listed as device only exit only at Grade 1, and the BEST Precision 2301 is a 2300 Series exit only mortise device. The Sargent 8304 is a night latch function device and can be ordered without trim as exit device only, or with ET trim in A, B, E, F, J, L, P or W lever styles if key access from outside is wanted later.
15) What mortise exit device has a recessed push pad instead of a rail or crossbar?
The Von Duprin 9475/9575 Impact Series is a mortise lock exit device with a recessed push pad, listed as Grade 1, non fire rated, for wide stile doors. The Sargent 8304 is a narrow stile mortise device in the 8300 Series, so the two suit different door constructions - use the Impact Series where abuse resistance on a wide stile leaf is the concern and the 8304 where the stile is narrow.
16) Do the mortise exit device alternatives to the Sargent 8304 cover door widths other than 36 inches?
The Sargent 8304 is offered in 32, 36, 42 and 48 inch sizes. Several peers are catalogued at a single 3 ft size, including the Falcon 25-M-EO at 36 inches, the Von Duprin 5575-3ft, the Von Duprin 8875-3FT at 36 inches and the Von Duprin 9875-3FT at 3 ft. If your openings vary in width, the 8304 size range covers more of them in one model.
17) Can I match the Sargent 8304 to the finishes already on my storefront doors?
Twelve finishes are offered, covering brass, bronze, stainless and painted: 03 bright brass clear coated, 04 satin brass clear coated, 09 bright bronze clear coated, 10 satin bronze clear coated, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 10BL dark oxidized satin bronze clear coated, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, BSP black suede powder coat and WSP white suede powder coat. For most aluminum storefront work, 32D satin stainless or BSP black matches existing door rails and closers.
18) Will the Sargent 8304 hold up on a high traffic entrance?
It is built for it. The 8304 is a commercial-only device with modular construction meant to last the lifetime of the building, and it exceeds ANSI/BHMA Grade 1 cycle and strength testing. Modular also means a worn component can be replaced rather than swapping the whole device, which matters when you are maintaining a fleet of openings across a portfolio.
