  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and frame surfaces, ensuring proper 41" centerline positioning from finished floor.
  3. Prepare door and frame by drilling required holes and routing as specified in manufacturer instructions, accommodating the 8-3/8" x 2-5/8" center case dimensions.
  4. Install appropriate rail size (E, F, J, or G) based on door width and secure all mounting hardware per manufacturer torque specifications.
  5. Install top strike (650) and bottom strike (606) components and adjust vertical rod mechanism for proper alignment and latching throughout the full range of motion.

Sargent AD8643E 10BE – Frequently Asked Questions

1) What does classroom function mean on the Sargent AD8643?
Classroom function means the outside lever trim is freewheeling, so access from the outside is controlled while the push rail always allows free egress from the inside. It is the usual choice for school and institutional openings where the corridor side stays locked but nobody can be trapped inside. If you only need exit with no outside trim at all, an exit-only device like the Falcon 25-M-EO or BEST Precision 2301 covers that instead.
2) Do I have to specify handing when ordering the Sargent AD8643?
Handing is required. The AD8643 is ordered either RHR (right hand reverse) or LHR (left hand reverse), so determine the swing before you order. It is not field reversible the way a non-handed device is. If you need something that can be flipped on site, the Von Duprin 5575 is listed as field reversible and the 8875 and 9875 as non-handed.
3) What door widths and rail sizes does the Sargent AD8643 cover?
Rail comes in four sizes (E, F, J, G) covering doors from 24 to 48 inches wide, and Sargent will cut the rail to the exact door width when you specify it. Orderable device sizes are 32, 36, 42 and 48 inches. Door openings up to 120 inches tall are supported, with the rail centerline at 41 inches from finished floor.
4) I need a fire-rated mortise exit device instead of the Sargent AD8643 - what should I look at?
For a labeled opening, the Corbin Russwin ED5600AL is a Grade 1 3 hour fire rated mortise exit device that will take classroom or passage lever trim, and the Adams Rite 3300 Series is a fire-rated wide stile mortise exit device for wood and hollow metal doors. Note that the AD8643 ships with hex key dogging standard on non-fire rated devices, so if you are moving to a labeled door the dogging function goes away and the Corbin or Adams Rite device is the more direct path.
5) What is the closest cross-brand equivalent to the Sargent AD8643 for a classroom-function mortise exit device?
The Corbin Russwin ED5600AL is the nearest cross-brand counterpart. Like the Sargent AD8643, it is a Grade 1 mortise exit device, and it is built to accept passage or classroom lever trim, so it lands on the same classroom-function opening. Two differences to weigh: the ED5600AL is a wide stile device listed for 1-3/4 inch doors, while the AD8643 covers 1-3/4 inch to 2-1/4 inch door thickness, and the Corbin trim is ordered separately where the Sargent takes ET trim with A, B, E, F, J, L, P or W levers as part of the order.
6) The AD8643 is for hollow metal doors - what mortise exit device works on a wood door?
Both Adams Rite mortise series are built for wood as well as hollow metal: the 3300 Series is the fire-rated version and the 8300 Series is the non-fire-rated life-safety version, both Grade 1 wide stile. By contrast the Von Duprin 8875, 9875 and the Detex 30 Series are all listed as not wood door compatible, so they are not the answer on a wood leaf. The Sargent AD8643 itself is engineered for hollow metal doors in the 1-3/4 inch to 2-1/4 inch thickness range.
7) My opening is a narrow stile aluminum storefront door - can I use the Sargent AD8643?
The AD8643 needs a minimum 4-1/2 inch stile width, which most aluminum storefront stiles do not give you. For narrow stile aluminum, the Adams Rite 8400 Series is a Grade 1 narrow stile life-safety mortise exit device made specifically for aluminum doors, and the Von Duprin 5575 is a Grade 1 narrow stile mortise device in a crossbar style, field reversible, for 1-3/4 inch doors. Measure the stile before ordering either one.
8) Why choose a concealed vertical rod device instead of a rim device or surface rods?
Concealed vertical rod means the rods run inside the door and latch at the head and the threshold, so you get two-point latching with nothing exposed on the door face. That suits a pair of doors with no center mullion and openings where appearance matters. The tradeoff is door prep: the door has to be built or prepped for concealed rods, which is why this is specified on hollow metal doors. A surface rod or rim device is easier to retrofit onto an existing door that was never prepped.
9) What lever trim options come with the Sargent AD8643?
Trim is ordered with the device: ET trim in A, B, E, F, J, L, P or W lever designs, or None if you want the device only. The ET trim is what delivers the freewheeling classroom operation, so pick a lever style that matches the other openings in the building. Ordering None gets you a push-to-exit device with no outside operation.
10) Is the Sargent AD8643 Grade 1, and what strikes does it use?
Grade 1, built for commercial traffic, with a stainless steel top bolt. It latches into a 650 top strike and a 606 bottom strike, so order those with the device and confirm the frame head and threshold can take them.
11) I do not need outside lever access - is there a simpler alternative to the Sargent AD8643?
Yes. If the door only needs egress with no outside trim, exit-only mortise devices cover it: the Falcon 25-M-EO is a Grade 1 wide stile exit-only device for 1-3/4 inch doors, the Detex 30 Series Advantex is a Grade 1 wide stile device-only configuration, and the BEST Precision 2301 is an exit-only mortise device with heavy wrought construction. The AD8643 differs in that it is a classroom-function device with freewheeling ET lever trim for controlled outside entry, so choose it only when you actually need keyed access from the pull side.
12) How does the Sargent AD8643 compare with the Von Duprin 9875 or 8875 mortise exit devices?
All three are Grade 1 wide stile mortise exit devices. The Von Duprin 9875 is a smooth case, non-handed device for 1-3/4 inch doors and the 8875 is a crossbar version, also non-handed for 1-3/4 inch doors; both are listed as not wood door compatible. The Sargent AD8643 is ordered handed as RHR or LHR, covers 1-3/4 inch to 2-1/4 inch door thickness, and is a concealed vertical rod device with top and bottom latching rather than a mortise-lock-only latch at the lock stile.
13) For a high-abuse opening, is the Von Duprin 9475/9575 a substitute for the Sargent AD8643?
They are not interchangeable, though both are Grade 1 wide stile mortise exit devices. The Von Duprin 9475/9575 Impact Series uses a recessed push pad intended to shield the touchpad from cart and traffic impact, and it is non-fire-rated. The Sargent AD8643 is a concealed vertical rod device with a conventional touchpad rail, offered in 32, 36, 42 and 48 inch sizes with freewheeling classroom lever trim. If abuse resistance at the pad is the driver, the Impact Series addresses it; if you need concealed top and bottom latching with keyed lever access, the AD8643 is the one that does that.
14) What finishes can I get the Sargent AD8643 in to match the rest of my building?
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, 10BL, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, plus BSP black and WSP white suede powder coat. 32D is the usual institutional standard if you are matching existing school or hospital hardware.
