Sargent AD8446E 10BE – Frequently Asked Questions

1) Will the Sargent AD8446 fit a narrow stile aluminum-style door, and what is the minimum stile width?
The AD8446 needs a 1-3/4 inch minimum stile width, and the stile has to be hollow with a 1-3/8 inch square inside dimension so the concealed vertical rods have somewhere to run. If your stile is solid, or narrower than 1-3/4 inches, this device will not go in. Door thickness range is 1-3/4 to 2-1/4 inch hollow metal.
2) What does storeroom function mean on the Sargent AD8446, and how does the freewheeling trim behave?
Storeroom function means the outside lever is always locked. You use a key to retract the latch and get in; pushing the touchbar from inside always gives free egress and relocks behind you. The lever is freewheeling, so it spins loose when locked instead of taking force through the lock case, which is what keeps it alive on abused doors like janitor closets, electrical rooms and stock rooms.
3) Which rail size do I order for my door width on the Sargent AD8400 narrow stile device?
Rails are factory cut to four sizes: 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. The ordering sizes offered are 32, 36, 42 and 48 inch, so pick the one that brackets your actual door width. Maximum door height is 120 inches.
4) Do I need to specify handing on the Sargent AD8446?
Yes, handing is required and there is no field-reversible option. You choose RHR (right hand reverse) or LHR (left hand reverse). Exit devices are always reverse bevel, so stand outside the door: if the hinges are on your right it is RHR. Get this wrong and the trim and latching will not work. If you want a non-handed device instead, the Von Duprin 5575 narrow stile crossbar mortise device is field reversible.
5) What is the closest narrow stile mortise exit device to the Sargent AD8446 from another brand?
For a narrow stile aluminum or hollow metal opening, the closest peers are the Von Duprin 5575 and the Adams Rite 8400 Series. The Von Duprin 5575-3ft is a Grade 1 narrow stile crossbar mortise lock exit device in a 3 ft size, field reversible, with a 1-3/4 inch door thickness. The Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device for aluminum doors. The Sargent AD8446 differs from both in that it is a concealed vertical rod device with storeroom function and freewheeling ET lever trim, latching at top and bottom rather than into the frame jamb only.
6) I need a fire rated mortise exit device but my doors are wide stile wood - what should I use instead of the Sargent AD8446?
The AD8446 is built for narrow stile hollow metal openings with a 1-3/4 inch minimum stile width, so it is the wrong device for a wide stile wood door. Two peers fit that opening: the Adams Rite 3300 Series is a fire rated Grade 1 mortise exit device for wood and hollow metal doors, and the Corbin Russwin ED5600AL is a Grade 1 three hour fire rated mortise exit device for 1-3/4 inch doors that can be ordered exit only or with passage or classroom lever trim.
7) Is the Von Duprin 9875 or 8875 a substitute for the Sargent AD8446?
They are not a direct swap. The Von Duprin 9875-3FT and 8875-3FT are both Grade 1 wide stile mortise exit devices for 1-3/4 inch doors, non-handed, and neither is fire rated or wood door compatible. The AD8446 is a narrow stile concealed vertical rod device, UL Fire and Panic listed, and is ordered by hand as RHR or LHR. If your opening is a narrow stile hollow metal door or the assembly is fire rated, the 9875 and 8875 will not prep into it.
8) How much does the Sargent AD8446 push bar stick out into the opening?
Neutral projection is 3 inches and it drops to 2-1/8 inches when the bar is depressed. Center case is 8-3/8 by 2-5/8 inches. Standard mounting centerline is 41 inches from finished floor, or 38 inches for elementary schools. Those numbers matter on tight vestibules and where a door swings past adjacent hardware.
9) Should I use a concealed vertical rod device or a rim device with a mullion on a pair of doors?
The AD8446 concealed vertical rod latches at the head and the threshold, so a pair of doors works with no center mullion and you get the full clear opening for carts and gurneys. Everything is inside the stile, so nothing is exposed to abuse. The trade off is prep: the stile has to be hollow with a 1-3/8 inch square inside channel, and bottom rod and strike maintenance means pulling the door. Rim plus removable mullion is easier to service but you lose the clear opening.
10) What lever trim choices come with the Sargent AD8446, and can I buy the device without trim?
Eight ET trim levers are offered: A, B, E, F, J, L, P and W. You can also order the device on its own with no trim if the opening is exit only or you are reusing existing trim. If you want a storeroom function, the ET lever is what gives you the keyed outside access.
11) Is the Sargent AD8446 heavy duty enough for a high traffic school or hospital exit?
It is a Grade 1 commercial device, the highest ANSI/BHMA duty level, with a stainless steel top bolt for corrosion resistance. Grade 1 is what specs call for on schools, hospitals and municipal buildings. For elementary schools note the device mounts at a 38 inch centerline rather than the standard 41 inches.
12) My opening is not fire rated - do I have a non-fire-rated mortise exit device option besides the Sargent AD8446?
Yes. The Adams Rite 8300 Series is a Grade 1 life-safety wide stile mortise exit device for wood and hollow metal doors, and the Adams Rite 8400 Series is the Grade 1 narrow stile version for aluminum doors; neither carries a fire rating. The Sargent AD8446 is UL Fire and Panic listed and is supplied with hex key dogging on non-fire rated devices, with cylinder dogging available, so it also suits a non-rated opening where you want dogging.
13) If I only need exit-only and no lever trim, is there a simpler alternative to the Sargent AD8446?
Yes. The AD8446 is a storeroom function device that pairs with freewheeling ET lever trim, though it can be ordered as exit device only. If the opening never needs outside key access, a dedicated exit only device is simpler: the Falcon 25-M-EO is a Grade 1 exit only mortise device for 36 inch wide stile doors with 1-3/4 inch thickness, the BEST Precision 2301 is an exit only mortise device with heavy wrought construction, and the Detex 30 Series Advantex is a Grade 1 device only mortise exit device. All three are wide stile, so confirm your stile width before switching.
14) For a high abuse opening like a gym or dorm corridor, what mortise exit device competes with the Sargent AD8446?
The Von Duprin 9475/9575 Impact Series is a Grade 1 mortise lock exit device with a recessed push pad for wide stile doors, designed so the pad sits back from the face of the device. The Sargent AD8446 uses an exposed pushbar with a 3 inch neutral projection that depresses to 2-1/8 inch, and it is a narrow stile device. The 9475/9575 is not fire rated, so on a fire rated assembly the AD8446 with its UL Fire and Panic listing is the one that carries the label.
15) Which of these mortise exit devices work on wood doors?
Among the peers, the Adams Rite 3300 Series and Adams Rite 8300 Series are both described for wood and hollow metal doors, and the Corbin Russwin ED5600AL is a Grade 1 mortise exit device for 1-3/4 inch doors. The Von Duprin 8875, 9875 and the Detex 30 Series are listed as not wood door compatible. The Sargent AD8446 is specified for hollow metal doors from 1-3/4 inch to 2-1/4 inch thick with a hollow stile requiring a 1-3/8 inch square inside dimension.
16) I need a crossbar style device instead of a pushbar - what is the alternative to the Sargent AD8446?
The Von Duprin 5575-3ft is a narrow stile crossbar mortise lock exit device, Grade 1, field reversible, for 1-3/4 inch doors, and the Von Duprin 8875-3FT is the wide stile crossbar version, Grade 1 and non-handed. The Sargent AD8446 uses a pushbar rail rather than a crossbar and is ordered in 32, 36, 42 and 48 inch sizes with a hand specified as RHR or LHR.
17) What finishes does the Sargent AD8446 come in for matching existing openings in a building?
Twelve finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE, 10BL, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, plus BSP black suede and WSP white suede powder coat. 32D satin stainless is the usual commercial standard, and the two powder coats are what to specify when you are matching painted aluminum storefront.
