    Adams Rite 8410-27136 – Frequently Asked Questions

    1) Which backset do I order on an Adams Rite 8400 mortise exit device?
    Three backsets are offered on the 8400: 31/32 inch, 1-1/8 inch, and 1-1/2 inch. The right one is whatever your existing aluminum door prep already is, measured from the face of the stile to the centerline of the cylinder hole. These are the standard narrow stile aluminum backsets, so on a retrofit you are matching the hole that is already in the door, not choosing a preference. Get this wrong and the cylinder and mortise pocket will not line up with the existing cutout.
    2) Do I have to specify handing on the Adams Rite 8400, or is it reversible in the field?
    Handing is reversible in the field on the 8400, but it still ships handed: orders are placed as either Left Hand Reverse or Right Hand Reverse. Exit devices are always a reverse-bevel hand because the door swings out for egress, so stand outside the door, note which side the hinges are on, and that gives you LHR or RHR. Ordering the opposite hand is recoverable here since the device reverses on the job, unlike many mortise locks.
    3) What cylinder does the Adams Rite 8400 take, and does it come with one?
    The 8400 accepts a standard mortise cylinder from 1 inch to 1-1/4 inch in length with an MS cam. The cylinder is a separate line item, so budget one per device if you are keying the outside for entry. If you are keying to an existing system, hand your locksmith the length and the MS cam requirement, since a standard mortise cam will not throw the mechanism. Adams Rite sells an 8000 Series cylinder kit for these devices, and the Adams Rite 4581 universal cam plug is the non-handed cam plug used across their mortise line.
    4) Can the Adams Rite 8400 be tied into an access control system with electric latch retraction?
    Electric latch retraction is available on the 8400, which lets a card reader or a remote release pull the latch back so the door can be pushed or pulled open without the push bar. That is the usual setup for a main entrance that is unlocked on a schedule and secured after hours. The 8400 also works with the Adams Rite 7800 Series electric strike if you would rather switch the strike than the device. Egress is unaffected either way: pushing the bar releases in a single motion regardless of the electrical state.
    5) My doors are wide stile hollow metal, not narrow stile aluminum. Which mortise exit device should I use instead of the Adams Rite 8400?
    The Adams Rite 8400 Series is built for narrow stile aluminum doors with a minimum 3-3/4" stile, so a wide stile opening calls for a different device. The wide stile mortise counterparts are the Von Duprin 9875-3FT, a 3 ft smooth case device, Grade 1 and non-handed for a 1-3/4" door; the Falcon 25-M-EO at 36", Grade 1, exit only, also for 1-3/4" doors; and the Detex 30 Series Advantex, Grade 1, device only exit only. The Von Duprin 8875-3FT is the wide stile crossbar version, 36", Grade 1, non-handed, for 1-3/4" doors. All of them are mortise devices like the 8400, so the lock stile still has to be prepped with a mortise pocket rather than for a rim strike.
    6) What is the closest cross-brand equivalent to the Adams Rite 8400 Series narrow stile mortise exit device?
    The Sargent 8304 is the nearest match in kind: a narrow stile mortise exit device rated ANSI/BHMA Grade 1, the same grade the Adams Rite 8400 Series carries, built in the Sargent 8300 Series. It is specified as a night latch function device, so outside access is by key. The other narrow stile mortise option is the Von Duprin 5575-3ft, Grade 1, field reversible, in a 3 ft length for a 1-3/4" door, which uses a crossbar rather than a push bar. The Adams Rite 8400 Series is ordered to the aluminum door prep in 31/32", 1-1/8", and 1-1/2" backsets and in 30", 36", 42", and 48" lengths, with an extruded aluminum push bar. When cross-referencing, match the backset and the stile width first: the 8400 needs a minimum 3-3/4" stile.
    7) Which mortise exit device carries a 3 hour fire rating?
    The Corbin Russwin ED5600AL is the 3 hour fire rated mortise exit device to specify. It is Grade 1, built for wide stile doors at 1-3/4" thickness, and it can be ordered exit only or set up to accept passage or classroom lever trim on the outside, with the trim ordered separately. Because it is a wide stile device, it goes on hollow metal or wood-thickness commercial doors rather than storefront. The Adams Rite 8400 Series is the Grade 1 mortise device for the narrow stile aluminum opening, minimum 3-3/4" stile, with 31/32", 1-1/8", and 1-1/2" backsets. If the drawing calls out a rated opening on a wide stile door, the ED5600AL is the device that answers it.
    8) Mortise or rim exit device for an aluminum storefront door, and what makes the 8400 a mortise?
    A mortise exit device puts the lock case inside a routed pocket in the lock stile, which is why the 8400 needs a 3-3/4 inch minimum stile and a specific backset. A rim device instead surface-mounts a latch on the face of the door into a strike on the frame stop, so it needs no pocket and no backset match, but the hardware sits proud on the door. Choose mortise when you want the case concealed in the stile and a cleaner storefront look, and when the door is already prepped for one. Choose rim when the existing door has no mortise pocket and you would rather not route it. The 8400 also carries a top latching mechanism with a rotating deadlatch bolt that engages a header strike, so it locks at the head as well as the stile.
    9) Is the Adams Rite 8400 heavy duty enough for a high traffic commercial entrance?
    The 8400 is an ANSI/BHMA Grade 1 device, the highest of the three BHMA duty grades and what is normally specified for commercial entrances, schools, and healthcare corridors. It is a commercial product, not residential, built with an extruded aluminum push bar and a hardened top latching mechanism with a rotating deadlatch bolt. For a school vestibule or an office lobby getting hundreds of cycles a day, Grade 1 is the level a spec writer will be asking for.
    10) What is the difference between the flat radius bevel and the weatherstrip face on the Adams Rite 8400?
    Two face shapes are offered: flat radius bevel, and radius with weatherstrip. The weatherstrip version is the one to order on an exterior door where the stile carries a weatherstrip channel, so the faceplate sits correctly against the existing seal. On an interior opening or an exterior door without a weatherstrip channel in the stile, the flat radius bevel is the standard face. Check what is on the door now before ordering, because the two faceplates are not interchangeable once the pocket is cut.
    11) What is included with the Adams Rite 8400, and what else do I need to order to finish the job?
    The 8400 comes with machine screws for mounting the device. Plan on ordering separately: a mortise cylinder of 1 to 1-1/4 inch with an MS cam if the outside is keyed, and the header strike hardware for the top bolt. If the opening is going on access control, that is where the electric latch retraction option or a 7800 Series electric strike comes in. Installation is a routed mortise pocket plus drilled mounting holes using the manufacturer templates, so a shop with a router setup or an experienced storefront installer is the realistic scope, not a maintenance tech with a hand drill.
    12) I have four aluminum entrance doors of different widths. Do I order the same Adams Rite 8400 for all of them?
    The 8400 is sized to the door, offered for 30, 36, 42, and 48 inch openings, so measure each leaf and order per door rather than buying four of one length. Backset, finish, and face shape can be kept identical across all four for a consistent look and one set of spare parts, provided every door has the same prep. What must match on each opening individually is the stile width, which has to be at least 3-3/4 inches, and the hand, ordered as LHR or RHR even though the device reverses in the field.
    13) Is the Sargent 1256NB-8710G a substitute for an Adams Rite 8400 Series device?
    No, and it is an easy one to mistake because both are Grade 1 and both are described for narrow stile doors. The Sargent 1256NB-8710G is an 84" surface mount vertical rod exit device with electric latch retraction, and it is fire rated. A vertical rod device runs rods along the door face and needs the door prepped for those rods and for top and bottom strikes. The Adams Rite 8400 Series is a mortise device: the case sets into a pocket in the lock stile, ordered to a 31/32", 1-1/8", or 1-1/2" backset to match the existing aluminum door prep. Moving between the two is a change of door and frame preparation, not a swap of devices on the same holes.
    14) Can I use a Sargent 810 in place of an Adams Rite 8400 on an egress door?
    No. The Sargent 810 is dummy pull exit device trim from the PE80 Series, dummy function, meaning it is a pull with no latching mechanism and no releasing action behind it. It is used where a matching appearance is wanted on a leaf that does not operate. The Adams Rite 8400 Series is the operating device, a Grade 1 mortise exit device for narrow stile aluminum doors with a minimum 3-3/4" stile and an extruded aluminum push bar. Any leaf that is part of an egress path needs an operating exit device, so dummy trim can only sit on the inactive leaf alongside it.
    15) I need electric latch retraction on a narrow stile aluminum door for access control. What are my options?
    The Adams Rite 8400 Series is available with electric latch retraction and is compatible with the 7800 Series electric strike, which keeps the whole assembly inside the mortise prep the aluminum door already has. The Sargent 1256NB-8710G is the other narrow stile device with electric latch retraction, but it is an 84" surface mount vertical rod unit, so it needs rod and top and bottom strike preparation rather than a mortise pocket. The Sargent 8904 is a nightlatch mortise device with 24VAC/DC operation, and it is a wide stile device, which puts it on hollow metal rather than storefront. For a storefront opening already prepped for a mortise device, staying with the 8400 Series avoids new door prep.
    16) Which mortise exit device accepts a lever on the outside instead of a key cylinder?
    The Corbin Russwin ED5600AL is the one specified when the outside needs a lever: it accepts passage or classroom lever trim, ordered separately, and it is a Grade 1 wide stile device for 1-3/4" doors. The Adams Rite 8400 Series handles outside access through a cylinder instead, taking standard 1" to 1-1/4" mortise cylinders with an MS cam, which is the usual arrangement where the stile is only 3-3/4" wide at minimum and there is no room for a full lever escutcheon. The Sargent 8304 narrow stile mortise device is also key operated from the outside, as a night latch function. Choose by what the outside has to do: key only on the storefront leaf, or a lever where the door is wide stile.
    17) If nobody needs to get in from the outside, is there a simpler exit only mortise device?
    Yes. Exit only means the device releases the door from the inside with no cylinder or trim on the outside, which removes the keying question from the order entirely. The Falcon 25-M-EO is exit only, Grade 1, 36" wide stile for a 1-3/4" door. The Detex 30 Series Advantex is a device only, exit only Grade 1 wide stile unit. The BEST Precision 2301 from the 2300 Series is an exit only mortise device with heavy wrought construction. All of these are mortise devices, so the lock stile still takes a pocket. On a narrow stile aluminum door with a 3-3/4" stile, the Adams Rite 8400 Series is the device sized for that opening, in 30", 36", 42", and 48" lengths.
    18) Do I have to specify handing on a mortise exit device, or are there non-handed options?
    It varies by device, and getting it wrong on a handed device means a return. The Adams Rite 8400 Series has field reversible handing and is ordered as left hand reverse or right hand reverse, so the hinge side and swing have to be confirmed before ordering even though the device can be reversed in the field. The Von Duprin 8875-3FT and the Von Duprin 9875-3FT wide stile mortise devices are non-handed, so one part number covers either swing. The Von Duprin 5575-3ft, the narrow stile mortise device, is field reversible in the same way the 8400 Series is. Stand outside the door, note which side the hinges are on and which way the leaf swings, and carry that to the order.
    19) What finish options does the Adams Rite 8400 come in, and can I match the other doors in my building?
    Seven finishes are offered on the 8400: 313 dark bronze anodized, 335 black anodized, 605 bright brass, 606 satin brass, 628 clear anodized, 629 bright stainless steel, and 630 satin stainless steel. On aluminum storefront, 628 clear anodized and 313 dark bronze are the two that typically match existing framing, since those are the common anodize colors on the door itself. If you are standardizing across a property, order every opening in the same finish code rather than by description, because bright and satin stainless read very differently side by side.
    20) Is there a mortise exit device built to take abuse from carts and equipment traffic?
    The Von Duprin 9475/9575 Impact Series mortise lock exit device is the one built around that problem, using a recessed push pad on a Grade 1 device for wide stile doors. The recessed pad keeps the actuating surface inside the case profile so it takes less of a direct hit from a passing cart. On narrow stile aluminum doors the Adams Rite 8400 Series is the Grade 1 mortise device for the opening, with an extruded aluminum push bar and a minimum 3-3/4" stile, and it is ordered in 30", 36", 42", and 48" lengths. The deciding factor is the door: the Impact Series belongs on a wide stile leaf, not on storefront.
    21) Sargent 8304 or Sargent 8904 - which one goes on an aluminum storefront door?
    The Sargent 8304 is the narrow stile one. It is a night latch function mortise exit device, Grade 1, from the 8300 Series, and narrow stile is what a storefront leaf needs. The Sargent 8904 is also a nightlatch mortise device, Grade 1, from the 8900 Series with 24VAC/DC operation, but it is a wide stile device and belongs on hollow metal. The Adams Rite 8400 Series is the narrow stile aluminum door device from Adams Rite, Grade 1, with a minimum 3-3/4" stile and backsets of 31/32", 1-1/8", and 1-1/2" to land on the existing prep. Measure the lock stile before deciding: if it is close to 3-3/4", a wide stile device will not fit the leaf.
