BEST 2308 626W 36 – Frequently Asked Questions

1) Will the BEST Precision 2308 mortise exit device fit a 1-3/4 inch door?
That is the only thickness it is built for. The 2308 is specified for 1-3/4 inch doors, on openings up to 4'-0" wide, with 3'-0" the standard configuration. If your openings are 1-3/8 inch, this is the wrong device. Backset is the standard commercial 2-3/4 inches, so it lands where a mortise lock prep normally sits.
2) Do I have to specify handing when ordering the Precision 2308 mortise exit device?
Yes, handing is a required choice: LHR (left hand reverse) or RHR (right hand reverse). Exit devices are always reverse-bevel because the door swings out. That said, the touchbar assembly, mortise lock and trim can be reversed in the field, and the complete device is reversible with the appropriate mortise strike, so a mis-ordered hand is recoverable on site rather than a return.
3) Will the 2308 mortise exit device latch into my existing strike?
The 2308 uses a stainless steel deadlocking latchbolt with a 3/4 inch throw and an anti-friction design, and it covers ANSI A115.1 (Type 86) mortise lock preparation. If the door already has a Type 86 mortise pocket and a mortise strike cut for a 3/4 inch throw, it lands. A cylindrical or rim strike will not work, that is a different prep entirely.
4) Can I replace another brand's mortise exit device with a Precision 2300 Series without redrilling the door?
That is what the 2300 Series is built to do. The devices are designed to retrofit into other manufacturers' mounting hole locations, so on an existing wide stile opening with a Type 86 mortise prep you are typically reusing the holes rather than patching and re-templating. Verify the door is 1-3/4 inch thick and the existing prep is Type 86 before you pull the old device.
5) Is the BEST Precision 2308 fire rated, and does that change what I can order?
It is offered both ways: Non-Rated (Standard) and Fire-Rated are a required selection, and the hardware is UL listed for panic and fire exit applications. The catch is dogging. Standard hex key dogging is not available on fire exit hardware, so if you pick the fire-rated build the touchbar cannot be held down for daytime free access. On a fire door that is correct behaviour, the latch has to stay projected.
6) Does the Precision 2308 come with lever trim, or do I order that separately?
Trim is a selection on the device. You can take it with 4908A, 4908B, 4908C, 4908D or 4908K lever trim, or as None (Device Only) if the opening is exit-only or the trim is already on site. Order it device-only by mistake and you get a push-to-exit with no outside operation. Compare that to the Corbin Russwin ED5600AL, where passage or classroom lever trim is accepted but is not included at all.
7) I need a 4 foot exit device for a wide opening. Does the Precision 2308 come long enough?
The 2308 is sold in 36 inch and 48 inch device lengths, covering openings up to 4'-0" wide, with 3'-0" the standard. Size the device to the door leaf, not the frame opening. Many competing mortise devices are cataloged only in a 3 foot length, such as the Falcon 25-M-EO at 36 inches and the Von Duprin 9875 and 8875 at 3 feet, so the 48 inch build is the one to specify for a full 4 foot leaf.
8) The opening is an aluminum storefront with a narrow stile. What mortise exit device works there instead of the Precision 2308?
The Precision 2308 is a wide stile style mortise device built for 1-3/4 inch doors up to 4 feet wide, not for narrow aluminum stiles. For a narrow stile aluminum door, the Adams Rite 8400 Series is a Grade 1 narrow stile mortise exit device made for aluminum doors. The Von Duprin 5575-3ft is another narrow stile Grade 1 mortise device, a crossbar type at 3 feet for 1-3/4 inch doors and field reversible. The Sargent 8304 is a narrow stile Grade 1 mortise device in night latch function if the outside trim needs to be key retracting only.
9) What is the closest equivalent to the BEST Precision 2308 mortise exit device from another manufacturer?
The Precision 2308 is a Grade 1 mortise exit device that takes lever trim, so the nearest match from another maker is the Corbin Russwin ED5600AL, a Grade 1 wide stile mortise exit device that accepts passage or classroom lever trim on 1-3/4 inch doors. The 2308 carries its lever trim as an ordered option in the 4908A, 4908B, 4908C, 4908D and 4908K styles, while the ED5600AL lever trim is not included with the device. Both are Grade 1; the Precision handles fire-rated and non-rated openings by rating selection, and the ED5600AL is a 3 hour fire rated device.
10) The door is wood. Which wide stile mortise exit devices suit a wood door?
The Precision 2308 is a Grade 1 mortise device for 1-3/4 inch doors that covers ANSI A115.1 Type 86 mortise lock prep. Among wide stile alternatives, the Adams Rite 3300 Series is a Grade 1 fire-rated mortise exit device for wood and hollow metal doors, and the Adams Rite 8300 Series is the Grade 1 non fire-rated counterpart for the same door materials. The Detex 30 Series, Von Duprin 8875-3FT and Von Duprin 9875-3FT are all Grade 1 wide stile mortise devices but are not wood door compatible.
11) The opening is fire rated. Which mortise exit devices can go on it?
The Precision 2308 is ordered as either non-rated or fire-rated, and is UL listed panic and fire exit hardware; on the fire-rated build the hex key dogging is not supplied, since fire doors must latch on every closing. From other makers, the Adams Rite 3300 Series is a fire rated Grade 1 wide stile mortise device for wood and hollow metal doors, and the Corbin Russwin ED5600AL is a Grade 1 3 hour fire rated mortise device. The Adams Rite 8300 and 8400 Series, the Von Duprin 5575, 8875, 9875 and the 9475/9575 Impact Series are all listed as not fire rated.
12) Can the Sargent 1256NB-8710G be used in place of the Precision 2308 mortise device?
No, they latch differently. The Sargent 1256NB-8710G is a Grade 1 narrow stile surface mount vertical rod exit device, 84 inch, fire rated, with electric latch retraction, so it latches at the head and sill through rods. The Precision 2308 is a mortise device that latches into the strike at the lock edge over ANSI A115.1 Type 86 mortise prep. Swapping between them changes the door and frame preparation completely. If electric latch retraction is the reason for the interest, the 2308 is ordered with ELR or with MLR motorized latch retraction.
13) We are replacing another manufacturer's mortise exit device. Will the Precision 2308 cover the existing holes?
The 2300 Series is designed to retrofit into other manufacturers' mounting hole locations, and it covers ANSI A115.1 Type 86 mortise lock preparation, which is the common mortise prep. Peers built on the same wide stile mortise pattern include the Corbin Russwin ED5600AL, the Falcon 25-M-EO and the Adams Rite 8300 Series, all Grade 1 wide stile mortise devices. A narrow stile device such as the Adams Rite 8400 Series or the Sargent 8304 sits on a different door section, so coming off one of those is not a hole for hole change.
14) What does the key control lever on the 2308 actually do?
The 2308 is the key control function in the 2300 Series: the outside lever is controlled by a cylinder, so a key governs whether the lever retracts the latch. Egress from the inside is always free through the touchbar. That is what makes it usable on a tenant or staff entrance where you want the door locked to the public but keyed for authorized entry, rather than an exit-only device like the Falcon 25-M-EO or the Detex 30 Series, which give you no outside operation at all.
15) Which dogging option should I pick on a Precision 2300 Series exit device?
Three choices: Hex Dogging (standard), Cylinder Dogging, or Less Dogging. Hex is a 1/4 turn hex key and is fine for back-of-house where staff hold the key. Cylinder dogging puts it on a keyed cylinder, which is what you want when the dogging needs to be under the same key control as the rest of the building and you do not want a loose hex wrench deciding whether the door is open. Less Dogging is the choice on fire-rated openings, where dogging is not permitted anyway.
16) Is the BEST Precision 2308 Grade 1 certified for a high traffic institutional opening?
BHMA certified to ANSI 156.3, Grade 1, and UL listed as panic and fire exit hardware. Cover, touchbar, device channel, filler and end cap are heavy wrought brass, bronze or stainless steel over an investment cast steel chassis. Grade 1 is the highest ANSI/BHMA durability tier and the level normally written into school, healthcare and government specs, so it standardizes cleanly across a facility.
17) What is the difference between the Precision 2308 touchbar and a crossbar mortise exit device?
The Precision 2308 uses a touchbar, with the cover, touchbar, device channel, filler and end cap in heavy wrought brass, bronze or stainless steel, and it is handed LHR or RHR with field reversal of the touchbar assembly, mortise lock and trim. The Von Duprin 8875-3FT is a Grade 1 wide stile crossbar mortise device in 36 inch for 1-3/4 inch doors and is non-handed, and the Von Duprin 5575-3ft is the narrow stile crossbar version, 3 feet and field reversible. Crossbar devices present a horizontal bar across the door instead of a full-width pad, which changes the look and the projection into the opening.
18) I only need exit from the inside with no outside lever. Is there a simpler mortise exit device than the Precision 2308?
Yes. The 2308 is built around a key control lever, and the lever trim is part of how it is ordered, though it can also be taken as device only. If the opening never needs outside entry, the Falcon 25-M-EO is a Grade 1 exit only mortise device in a 36 inch wide stile size for 1-3/4 inch doors, and the Detex 30 Series Advantex is a Grade 1 wide stile mortise device supplied as device only, exit only. Both drop the outside trim and its keying entirely.
19) Is the Sargent 810 an alternative to the Precision 2308?
No. The Sargent 810 is dummy exit device trim in the PE80 Series, a dummy function pull with no latching mechanism behind it. The Precision 2308 is a complete mortise exit device with a stainless steel deadlocking latchbolt at 3/4 inch throw and an anti-friction design, UL listed as panic and fire exit hardware. A dummy pull is used on the inactive leaf of a pair or where a matching appearance is wanted without any latching, so it cannot replace an egress device on a required exit.
20) I need a night latch function mortise exit device rather than a key control lever. What are the options?
The Precision 2308 is the key control lever function, ordered with 4908 series lever trim or as device only. If the outside trim should retract the latch by key alone with no lever, the Sargent 8904 is a Grade 1 wide stile mortise exit device in night latch function with 24VAC/DC operation, and the Sargent 8304 is the Grade 1 narrow stile mortise device in night latch function. Function is set by the device you order, so confirm it against the hardware schedule before the door is prepped.
21) The doors take heavy abuse in a school corridor. Is there a mortise exit device built for that instead of the Precision 2308?
The Precision 2308 is BHMA certified to ANSI 156.3 Grade 1 with cover, touchbar and channel in heavy wrought brass, bronze or stainless steel over an investment cast steel chassis. If a recessed pad is preferred so the bar cannot be caught by carts or equipment, the Von Duprin 9475/9575 Impact Series is a Grade 1 wide stile mortise device with a recessed push pad, not fire rated. Both are Grade 1; the difference is the exposed touchbar versus the recessed pad profile.
22) Which mortise exit devices are non-handed if we do not want to track handing on the order?
The Precision 2308 is handed and is ordered LHR or RHR, though the touchbar assembly, mortise lock and trim may be reversed in the field, with complete device reversibility available using the appropriate mortise strike. If handing is better avoided on a multi-door order, the Von Duprin 8875-3FT and the Von Duprin 9875-3FT are both Grade 1 wide stile mortise devices listed as non-handed for 1-3/4 inch doors, and the Von Duprin 5575-3ft is narrow stile and field reversible. Note that the 8875 and 9875 are not wood door compatible.
23) Will the Precision 2308 match the finish on the rest of my building's door hardware?
Ten finishes are offered: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 622 matte black, 625 bright chrome, 626W satin chrome weatherized, 628 satin aluminum, 630 satin stainless steel and 690 statuary dark bronze. Those are BHMA finish numbers, so a 630 device sits next to any other 630 hardware in the building. For exterior openings the 626W weatherized satin chrome is the one to specify, and it pairs with the WTS or WTDS weatherized touchbar monitoring switches.
