Sargent WD8643E 10BE – Frequently Asked Questions

1) Will the Sargent WD8643 exit device fit my door stile and thickness?
The WD8643 is a wide stile device: it needs at least 4-1/2 inches of stile width and a door thickness of 1-3/4 to 2-1/4 inches. If your opening is a narrow stile aluminum door, this is the wrong device. Door widths from 24 to 48 inches are covered by factory-cut rails, with door height up to 120 inches.
2) What does classroom function mean on the Sargent WD8643, and how does the freewheeling trim behave?
Classroom function with freewheeling trim: the outside lever is controlled by key, and when the device is locked the lever spins free instead of binding, so nobody can force the trim and damage the lock. Egress from the inside is always free by pushing the pad. Sargent lists it as a classroom-function device in the WD8600 Series.
3) Do I need a mullion to use the WD8643 on a pair of doors?
No. The WD8643 is a concealed vertical rod device, so it latches at the head and the threshold on its own leaf using a top strike 650 and bottom strike 606. That lets it secure a pair of doors without a center mullion, which is the reason people pick vertical rod over a rim device. If you want a rim device instead, you have to add a removable mullion to a pair.
4) Is handing required when ordering the Sargent WD8643?
Yes, handing is a required selection. The WD8643 is built either RHR (right hand reverse) or LHR (left hand reverse), so you have to know which way the door swings and which side the hinges are on before you order. Some competing mortise devices are field reversible or non-handed, but this one is not ordered that way.
5) Does the Sargent WD8643 come with lever trim, or do I order that separately?
Trim is a selection you make on the order. You can take the device with ET trim in A, B, E, F, J, L, P or W lever design, or choose Exit Device Only if you are reusing trim or want a pull. If you need the classroom key control described for this device, order it with an ET lever trim.
6) Can I hold the WD8643 unlocked during school hours?
Yes. Hex key dogging is standard on non-fire rated WD8643 devices, so you can depress and hold the pushpad down for push-pull traffic during the day. Cylinder dogging is available as an option if you would rather staff dog the device with a key than a hex wrench, and electric dogging (option 58) or remote dogging / latch retraction (option 56) can be ordered where you want it controlled from the access control system.
7) Which alternative to the Sargent WD8643 carries a stated fire rating?
The Adams Rite 3300 Series is a Grade 1 wide stile fire-rated mortise exit device for wood and hollow metal doors, and the Corbin Russwin ED5600AL is a Grade 1 wide stile mortise device rated 3 hour that accepts classroom or passage lever trim. The Sargent WD8643 ships with hex key dogging standard on non-fire-rated applications, with cylinder dogging optional, so confirm the labeled opening requirements before substituting either way.
8) Which mortise exit device should be used instead of the Sargent WD8643 on a narrow stile aluminum door?
The WD8643 is a wide stile device and calls for a 4-1/2 inch minimum stile, so it does not suit a narrow stile aluminum opening. The Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device for aluminum doors. The Von Duprin 5575 is another narrow stile Grade 1 mortise exit device, in a 3 ft crossbar style and field reversible.
9) If the opening only needs free egress with no outside lever, what is a simpler alternative to the Sargent WD8643?
Exit-only mortise devices cover that. The Falcon 25-M-EO is a Grade 1 wide stile exit-only mortise device in a 36 inch, 3 ft size for 1-3/4 inch doors, the Detex 30 Series Advantex is a Grade 1 wide stile device-only mortise unit, and the BEST Precision 2301 is a 2300 Series exit-only mortise device with heavy wrought construction. The WD8643 carries classroom function with freewheeling ET lever trim, which those exit-only devices do not provide.
10) What is the closest equivalent to the Sargent WD8643 if the opening needs a classroom-function mortise exit device from another manufacturer?
The Corbin Russwin ED5600AL is the nearest peer: a Grade 1 wide stile mortise exit device that accepts passage or classroom lever trim, listed for 1-3/4 inch doors. The WD8643 is a Grade 1 wide stile device with classroom function and freewheeling ET lever trim, ordered with the trim lever design as part of the configuration, while the ED5600AL is an exit-only chassis that takes the classroom lever trim separately. The Corbin Russwin device also carries a 3 hour fire rating.
11) Is a Von Duprin 9875 or 8875 a substitute for the Sargent WD8643?
They are not a direct swap. The Von Duprin 9875 and 8875 are both Grade 1 wide stile mortise exit devices for 1-3/4 inch doors, non-handed, and both are listed as not wood door compatible; the 9875 is a smooth case touchpad style and the 8875 is a crossbar style. The WD8643 is a concealed vertical rod device ordered by handing, RHR or LHR, for hollow metal doors of 1-3/4 inch to 2-1/4 inch thickness, so the door prep and the latching hardware differ.
12) What size should I order for a 36 inch door, and what are the rail options?
Rails are factory cut and ordered by size: 32, 36, 42 or 48 inches. Match the size to the door leaf width, so a 36 inch door takes the 36 inch device. Sargent designates these rails E, F, J and G across the 24 to 48 inch door width range.
13) What mounting height should the exit device be installed at?
Set the device centerline at 41 inches from the finished floor for standard applications, or 38 inches for elementary schools and accessibility. Plan the concealed rod routing in the door before you drill, and allow for the center case at 8-3/8 x 2-5/8 inches. The pushbar travels from 3 inches neutral to 2-1/8 inches depressed, so keep that clearance in front of the pad.
14) Is the WD8643 heavy duty enough for a high traffic school or hospital entry?
It is a BHMA Grade 1 device, the heaviest commercial duty rating, and the top bolt is stainless steel for corrosion resistance. Grade 1 is what institutional specs normally call for on high-traffic egress openings.
15) What is the difference between a concealed vertical rod device like the WD8643 and a mortise exit device?
A concealed vertical rod device latches top and bottom with rods hidden inside the door, so you get a clean face and a pair of doors secured without a mullion. A mortise exit device latches into the frame or mullion at the lock edge with a mortise lock body, which is simpler to service but does not secure a pair on its own. If you want the mortise route on a wide stile door, the Corbin Russwin ED5600AL and the Von Duprin 9875 are both Grade 1 wide stile mortise devices ZenSupply carries.
16) What wide stile mortise exit device should be specified if the Sargent WD8643 opening is a wood door?
The Adams Rite 3300 Series is a Grade 1 wide stile mortise exit device for wood and hollow metal doors and is fire rated; the Adams Rite 8300 Series is the same wide stile Grade 1 mortise device for wood and hollow metal in a non-fire-rated life-safety version. The Sargent WD8643 is specified for wide stile hollow metal doors with a 1-3/4 inch minimum thickness.
17) Do any alternatives to the Sargent WD8643 avoid having to specify handing?
Yes. The Von Duprin 9875 and 8875 wide stile mortise exit devices are listed as non-handed, and the Von Duprin 5575 narrow stile mortise device is field reversible. The Sargent WD8643 is ordered by handing, either RHR right hand reverse or LHR left hand reverse, because of its concealed vertical rod construction.
18) Which mortise exit devices cover door widths beyond 36 inches as alternatives to the Sargent WD8643?
The Sargent WD8643 uses factory-cut rails for door widths from 24 inches to 48 inches and is ordered in 32, 36, 42 and 48 inch sizes. Among comparable devices, the Falcon 25-M-EO is listed at 36 inch 3 FT, the Von Duprin 8875 at 36 inch, and the Von Duprin 9875 at 3 ft, so those are single-size 3 foot devices rather than a range covering 42 and 48 inch leaves.
19) What finishes does the Sargent WD8643 come in so I can match the other doors in my 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, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, plus BSP black and WSP white suede powder coat. 32D satin stainless is the usual match for institutional openings, and the powder coats are the option when you are matching painted doors.
