BEST 2403 630 36 – Frequently Asked Questions

1) Will the BEST 2403 rim exit device fit a 2-inch thick aluminum storefront door?
Yes. The 2403 narrow stile rim device covers doors from 1-3/4 inches to 2-1/4 inches thick, so 2 inches is inside the range. Standard build is set up for a 1-3/4 inch thick, 3'-0 inch wide door, and the device handles openings up to 4'-0 inches wide. One limit to note: it is not rated for wood doors, so keep it on metal or aluminum leaves.
2) Do I need to specify handing when ordering a BEST 2403 exit device?
The 2403 device itself is non-handed and works on single doors and on pairs with a mullion, so no handing is needed for the device. Handing only comes into play if you add lever trim: with any of the 2903 lever trims you have to call out RHR (right hand reverse) or LHR (left hand reverse). Order the C grip pull trim, or device only, and handing drops out of the equation entirely.
3) Can a BEST 2403 rim device be used on a pair of doors?
Yes, but only with a center mullion. A rim device latches into a strike on the frame or mullion, so on a pair you need a removable or fixed mullion for the 2403 to latch against. For a pair with a clear opening and no mullion, you want a vertical rod device instead, such as the Hager 4601 narrow stile concealed vertical rod device.
4) Is the BEST 2403 exit device available fire rated, and what do I lose if I order it that way?
Both. Rating is a required choice at order time between non-rated (standard) and fire rated. The 2403 is UL Listed for panic and for fire exit hardware. The trade-off on the fire rated build is dogging: the 1/4 turn hex key dogging that comes standard is not available on fire exit hardware, because a fire door has to latch on every cycle. If you need the touchbar held down for daytime free passage, you have to stay non-rated.
5) Will the BEST 2403 latch into the strike that is already on my frame?
The 2403 uses a stainless steel deadlocking latchbolt with a 3/4 inch throw, which is the standard rim strike engagement, so it will generally pick up an existing rim strike prep on a metal frame. Check that the existing strike is a rim strike, not a mortise or cylindrical lip strike, and that the latch centerline lines up with the touchbar height, which is 39-15/16 inches from the floor as furnished. That height can be varied if the existing prep sits differently.
6) Should I use a narrow stile rim device like the BEST 2403 or a wide stile device?
Stile width on the door decides it. The 2403 is a narrow stile device, built for aluminum and glass storefront leaves where the vertical stile is too slim to take a wide chassis. If your door has a full wide stile, a wide stile device gives you more mounting surface and more trim options: the Corbin Russwin ED5200 and the TownSteel ED9700 are Grade 1 wide stile rim devices for 1-3/4 inch doors. Putting a narrow stile device on a wide stile door works but wastes the pad width; putting a wide stile device on a narrow storefront stile usually does not fit at all.
7) What narrow stile rim exit device matches the BEST 2403 door thickness range of 1-3/4 to 2-1/4 inches?
The Adams Rite 8800 Series 30 inch narrow stile rim device lists the same 1-3/4 inch to 2-1/4 inch door thickness range, is Grade 1, and like the 2403 is not wood door compatible. The 8800 is not fire rated, so on a fire opening you would order the 2403 in its fire rated configuration instead. If the door is wide stile rather than narrow, the DORMA 9300 Series 48 inch also carries that 1-3/4 inch to 2-1/4 inch range at Grade 1.
8) What is the closest narrow stile rim exit device to the BEST 2403 if I need a Grade 1 device on an aluminum door?
The Corbin Russwin ED4200 is the nearest match in a different brand. Both are narrow stile rim devices carrying Grade 1, and neither is rated for wood doors. The ED4200 lists a 1-3/4 inch door thickness, while the BEST 2403 covers 1-3/4 inch through 2-1/4 inch. The ED4200 is described as exit only and accepts trim; the 2403 is ordered with pull or lever trim or as device only, in 36 inch and 48 inch lengths. Confirm your actual door thickness before you swap, because that is where the two part company.
9) Is the SDC MSB550 switch bar a substitute for the BEST 2403 rim exit device?
No. The SDC MSB550 Series 36 inch is a mechanical switch bar that releases an electromagnetic lock, and the SDC SureExit PSB560 Series 36 inch is a pressure sense bar. Both fit narrow or wide stile doors, but they signal a lock to release rather than carrying a latch themselves. The BEST 2403 is a rim exit device with its own stainless steel deadlocking latchbolt at 3/4 inch throw, UL Listed for panic and fire exit hardware. If the door has no maglock and needs to latch on its own, the switch bars will not do the job.
10) What does key retracts latchbolt mean on the BEST 2403, and how is it different from a night latch?
On the 2403, a key in the outside cylinder pulls the latchbolt back so the door can be pushed open from outside without touching the touchbar. That is momentary, key-controlled outside access with the door staying secure the rest of the time. A night latch function like the Sargent 8504 narrow rim device does the same job through the trim rather than a key retract at the device. Pick key retract when you want the outside side to stay blank and controlled by cylinder only.
11) Which dogging option should I order on a BEST 2403 exit device?
Three choices. Hex dogging is standard: a 1/4 turn hex key holds the touchbar depressed so the door pushes free during business hours. Cylinder dogging swaps that for a keyed cylinder, which is what most schools and facilities want so a maintenance hex wrench is not the only control. Less dogging means the latch always projects, and that is what you take on a fire rated 2403, since dogging is not offered on fire exit hardware.
12) What size BEST 2403 exit device do I order for a 3-foot door versus a 4-foot door?
Two device lengths are offered, 36 inch and 48 inch. Order the 36 inch for a 3'-0 inch leaf, which is the standard configuration, and the 48 inch for wider leaves up to the 4'-0 inch maximum opening the 2403 covers. Size the bar to the leaf, not to the frame opening of a pair.
13) What trim do I need to order with a BEST 2403 rim exit device for outside entry?
The device alone is exit only, so outside access comes from the trim you specify. Choices are the 2003C pull trim with a C grip, or lever trim in four designs: 2903A, 2903B, 2903C and 2903D. Lever trims require a handing call-out (RHR or LHR). You can also order None (device only) if the outside face stays blank or you already have trim on the door.
14) Which narrow stile rim device should I order instead of the BEST 2403 if the spec calls for extra heavy duty?
The Detex 40 Advantex Series is a narrow stile rim exit device listed at extra heavy duty and Grade 1, not wood door compatible. The BEST 2403 is Grade 1 to ANSI 156.3 with heavy wrought brass, bronze or stainless steel cover, touchbar and channel over an investment cast steel chassis. If the drawing states extra heavy duty as a duty level rather than a grade, the Detex 40 is the one that carries that wording.
15) Is there a simpler narrow stile rim exit device than the BEST 2403 if I only need push-to-exit with no key function?
Yes. The Falcon 19-R Series 36 inch and the Falcon 1590EO 42 inch are both Grade 1 narrow stile rim devices listed as exit only, as is the Falcon 1790EO at 42 inch. The TownSteel ED3700 36 inch and ED8900 36 inch are Grade 1 narrow stile heavy duty rim devices as well. The BEST 2403 is built around key retracts latchbolt operation, so its cylinder pulls the latch back from the outside; the exit only devices do not offer that outside function. Choose by whether anyone needs to key back in through that door.
16) How does the Sargent 8504 nightlatch compare to the BEST 2403 key retracts latchbolt device?
Both are narrow stile rim devices at Grade 1. The Sargent 8504 is a nightlatch function device, where the outside cylinder retracts the latch for entry. The BEST 2403 is the key retracts latchbolt function, the same idea of keyed outside access, and it can be ordered with 2003C pull trim or 2903 A, B, C or D lever trim, or as device only. The 2403 also covers 1-3/4 inch to 2-1/4 inch doors and comes in 36 inch and 48 inch. Confirm which trim the opening was specified for before substituting either way.
17) Can I use a Hager 4601 concealed vertical rod device where a BEST 2403 was specified?
Not as a direct swap. The Hager 4601 Series 36 inch is a Grade 1 narrow stile concealed vertical rod exit device, so it latches top and bottom into the frame and floor and requires a door prepped for concealed rods. The BEST 2403 is a rim device that latches into a strike on the frame at the latch height. Same narrow stile family, entirely different door prep and strike work.
18) What do I order in place of the BEST 2403 for a 48 inch wide stile door?
The BEST 2403 is a narrow stile device offered in 36 inch and 48 inch. If the door is wide stile, the Corbin Russwin ED3200 is a Grade 1 48 inch crossbar rim device for 1-3/4 inch doors, the DORMA 9300A is a Grade 1 heavy duty 48 inch wide stile rim device for 1-3/4 inch to 2-1/4 inch doors, and the Cal-Royal 5500 is a 48 inch wide rim device with push bar. Match the door thickness first, then the actuation style your building already uses.
19) What is a comparable narrow stile rim device to the BEST 2403 with hex key dogging?
The Stanley Security QED200 Series is a Grade 1 heavy duty narrow stile rim exit device with hex key dogging, and the Dormakaba QED200 is a Grade 1 heavy duty narrow exit device supplied as a 36 inch device. The BEST 2403 carries 1/4 turn hex key dogging as standard and can also be ordered with cylinder dogging or less dogging. If the facility keys its dogging rather than using a hex wrench, the cylinder dogging build of the 2403 is the one to specify.
20) The Adams Rite EX88 and the BEST 2403 are both narrow stile rim devices - what is the difference?
The Adams Rite EX88 is an interlocking rim exit device with a narrow stile design, Grade 1, not fire rated. The BEST 2403 is a narrow stile rim device with a stainless steel deadlocking latchbolt at 3/4 inch throw and is available fire rated as well as non-rated. The interlocking style engages a starwheel strike rather than a conventional rim strike, so the frame preparation differs. Confirm which strike is already in the frame before ordering either.
21) Can I match a BEST 2403 exit device to the finishes already on my other doors?
Ten finishes are offered on the 2403: 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. For a building already standardized on aluminum storefront, 628 satin aluminum and 630 satin stainless are the usual pulls; 626W is the one to specify on exterior openings that see weather.
22) Is there a lower cost alternative to a Grade 1 narrow stile rim device for a low-traffic interior door?
If the opening does not need Grade 1, Cal-Royal offers Grade 2 rim devices with a heavy duty chassis, the 5000 in 36 inch and the 5500 in 48 inch with a push bar, both non fire rated and for non-wood doors. The BEST 2403 stays the choice where you need Grade 1 to ANSI 156.3, a fire rated option, a 2-1/4 inch door capability, or electrified latch retraction, none of which the Grade 2 devices are listed for.
