Installation & Operation

  1. Review manufacturer specifications and verify door preparation requirements including door thickness (1-3/4" to 2-1/4"), stile width (4-1/2" minimum), and door width for proper rail selection.
  2. Use manufacturer-provided templates to mark mounting hole locations accurately on door and frame surfaces, ensuring proper device centerline positioning at 41" from finished floor for standard applications.
  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 rail assembly (factory-cut to door width if specified) and secure all mounting hardware per manufacturer torque specifications using supplied machine screws.
  5. Mount top and bottom strikes (650 Top Strike and 606 Bottom Strike) and adjust for proper alignment with vertical rod mechanism.
  6. Test device operation to verify proper function including pushbar travel (3" neutral to 2-1/8" depressed) and make final adjustments as needed. Refer to manufacturer documentation for complete installation details and troubleshooting.

Sargent WD8640E 10BE – Frequently Asked Questions

1) How do I pick the right rail size for a Sargent WD8640 concealed vertical rod device?
Rail selection follows door width: E Rail covers 24 to 32 inches, F Rail 33 to 36 inches, J Rail 37 to 42 inches, and G Rail 43 to 48 inches. Orderable sizes are 32, 36, 42 and 48 inches, so measure the actual door leaf width before you specify. Rails are factory cut to door width.
2) What does the dummy function on the Sargent WD8640 actually do?
Dummy function with freewheeling trim means the lever spins free and does not retract latches. It is used to keep the appearance consistent with active exit devices on adjacent leaves or openings while the pushbar side handles egress. If you need the outside lever to unlatch the door, you need an active function, not the WD8640.
3) Do I have to specify handing when ordering the Sargent WD8640?
Yes, handing is required: RHR (right hand reverse) or LHR (left hand reverse). Stand outside the door, on the side that does not receive the pushbar, and determine the swing before ordering. There is no field-reversible option on this configuration.
4) The WD8640 needs a 4-1/2 inch stile. What mortise exit device works on a narrow stile aluminum door instead?
The Sargent WD8640 is a wide stile device requiring a 4-1/2 inch minimum stile width, so it will not fit a narrow stile aluminum storefront door. For those openings, the Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device built for aluminum doors, and the Von Duprin 5575 is a Grade 1 narrow stile crossbar mortise device for 1-3/4 inch doors that is field reversible.
5) Is a Von Duprin 9875 a direct substitute for the Sargent WD8640?
They are not interchangeable in prep. The Sargent WD8640 is a concealed vertical rod device that latches at the top and bottom of the door and is handed RHR or LHR. The Von Duprin 9875-3FT is a smooth case wide stile mortise exit device, non-handed, for 1-3/4 inch doors and listed as not wood door compatible, and the Von Duprin 8875-3FT is the crossbar version in the same 36 inch wide stile non-handed arrangement. Both mortise the lock into the door edge rather than running rods to top and bottom strikes, so the door and frame preparation differs.
6) Can I get classroom or passage lever function instead of the dummy trim on the Sargent WD8640?
The Sargent WD8640 is a dummy function device with freewheeling trim, so the outside lever does not retract a latch. If the opening needs a keyed or passage lever on the outside, the Corbin Russwin ED5600AL is a Grade 1 wide stile mortise exit device for 1-3/4 inch doors that accepts passage or classroom lever trim, sold exit only with the trim ordered separately.
7) What door prep and clearance does the Sargent WD8640 center case need?
Center case measures 8-3/8 x 2-5/8 inches, with 3 inch neutral projection and 2-1/8 inch depressed projection off the door face. Standard device centerline is 41 inches from finished floor. Top and bottom latching uses the 650 top strike and 606 bottom strike.
8) Should I use a concealed vertical rod device or a surface mounted one on a pair of doors?
Concealed vertical rod, like the WD8640, runs the rods inside the door so nothing shows on the face, which is why it gets specified where appearance matters and where rods would otherwise be damaged. It requires a door prepped for concealed rods, so it is a new door or factory-prepped door decision, not a quick retrofit. A surface vertical rod or a mortise exit device such as the Von Duprin 9875 or the Falcon 25-M-EO mounts on the face and is easier to add to an existing door.
9) What electrified and alarm options can I add to the Sargent WD8640?
Options include AL alarmed (requires a 36 inch minimum door width), BT beacon, PL SARGuide photoluminescent, TL SARGuide illuminated touchpad, plus monitoring and control options 53 latchbolt monitor switch, 54 internal micro switch in ET control, 55 signal switch in rail, 56 remote dogging / latch retraction, 58 electric dogging, and 59 Electroguard. These are specified at order time.
10) What lever trims and finishes come on the Sargent WD8640?
Trim choices are ET Trim in A, B, E, F, J, L, P and W lever styles, or device only with no trim. Twelve finishes are offered, from 03 bright brass and 04 satin brass through 10B dark oxidized satin bronze oil rubbed, 20D dark statuary bronze, 32 bright stainless and 32D satin stainless, plus BSP black suede and WSP white suede powder coat. For a property manager matching existing openings, 32D is the usual commercial standard.
11) Is the Sargent WD8640 heavy duty enough for a school or hospital corridor?
It carries a Grade 1 rating, which is the highest ANSI/BHMA commercial durability tier, and it is a commercial-rated device intended for high traffic openings in schools, healthcare, retail, government and multi-tenant buildings.
12) What are the alternatives to the Sargent WD8640 for a wide stile hollow metal door?
If you want a mortise exit device rather than concealed vertical rods, ZenSupply carries the Corbin Russwin ED5600AL, a Grade 1 wide stile mortise device rated 3 hour fire that accepts passage or classroom lever trim on 1-3/4 inch doors, and the Von Duprin 8875 crossbar wide stile mortise device, Grade 1 and non-handed. The Detex 30 Series Advantex is another Grade 1 wide stile mortise option, though it is not rated for wood doors. For an aluminum narrow stile opening none of these apply; the Adams Rite 8400 Series is the narrow stile choice.
13) I do not need lever trim, just a push bar for egress. What is simpler than the Sargent WD8640?
The Sargent WD8640 is supplied with dummy function freewheeling trim and offers ET lever trim options in A, B, E, F, J, L, P and W levers. If the opening only needs a device with no outside trim, exit only mortise devices include the BEST Precision 2301 Series with heavy wrought construction, the Falcon 25-M-EO in a 36 inch wide stile 3 foot size, and the Detex 30 Series Advantex, which is a Grade 1 wide stile device supplied as device only.
14) What wide stile mortise exit device should I look at for a high abuse opening compared to the Sargent WD8640?
The Sargent WD8640 is a Grade 1 wide stile device with a touchpad style rail in sizes from 32 inch through 48 inch. For openings that take heavy abuse, the Von Duprin 9475/9575 Impact Series is a Grade 1 wide stile mortise lock exit device with a recessed push pad, and the BEST Precision 2301 Series is described with heavy wrought construction. Note the 9475/9575 is listed as not fire rated.
15) Does anything comparable to the Sargent WD8640 come non-handed so I do not have to specify hand?
The Sargent WD8640 must be ordered RHR or LHR because of the concealed vertical rod mechanism. If handing is a concern on a mixed order, the Von Duprin 8875-3FT and 9875-3FT wide stile mortise devices are both non-handed, and the Von Duprin 5575 narrow stile crossbar device is field reversible.
