BEST 2108 628 48 – Frequently Asked Questions

1) Is the BEST Precision 2108 a 48 inch device, and can it be cut down for a narrower door?
The 2108 covered here is the 48 inch size, built for 48 inch wide openings. If your door leaf is narrower, order the shorter length of the 2100 Series rather than trimming this one. The device is wide stile, so it needs the stile width a standard hollow metal or wide-stile aluminum door provides.
2) Do I have to specify handing when ordering the 2108 exit device?
The device itself is nonhanded and reversible for all functions and trims, shipped RHRB as standard. Handing only comes into play if you add lever trim, where you choose LHR (left hand reverse) or RHR (right hand reverse).
3) Will the 2108 latch into the strike that is already on my frame?
The latchbolt is stainless steel, deadlocking, with a 3/4 inch throw, and the 2100 Series is built to retrofit into other manufacturers' mounting hole locations. That covers the door face prep, but a rim device latches into its own surface rim strike on the frame stop, so plan on using the strike that comes with the device unless the existing one is a matching rim strike at the same height.
4) Can the BEST Precision 2108 work with an access control reader and electric trim?
Yes. It uses a center driven cam that accepts access control exterior trim tailpieces, and the tailpiece needs at least 50 degrees of rotation to retract the latch. On the device side you can also order electric latch retraction (ELR) or motorized latch retraction (MLR) so the latch is held retracted during unlocked hours.
5) Does the 2108 rim device work on a pair of doors without a mullion?
A rim device latches into a strike on the frame stop, so on a pair of doors it needs a removable mullion between the leaves to give the latch something to catch. If you cannot use a mullion, a vertical rod device is the right type instead, such as the Hager 4501 Series concealed vertical rod exit device with wide stile pushpad.
6) The BEST Precision 2108 is not fire rated. What fire rated 48 inch rim exit device can I use on a labeled opening?
The Marks USA M9900F 48 inch rim panic exit device is fire rated and sized for 48 inch doors, with a panic protector end cap, and is cataloged exit only. The Sargent 12-8810-LTRIM is another fire rated wide stile Grade 1 rim device if you need lever trim rather than push-to-exit. The BEST Precision 2108 carries a Fire Rating value of No, so for a labeled door assembly one of the fire rated devices is the correct specification.
7) What is the closest equivalent to the BEST Precision 2108 48 inch wide stile rim exit device from another manufacturer?
The DORMA 9300 Series 48 inch wide stile panic rim exit device is the nearest match on the core specs: it is a Grade 1, heavy duty, wide stile rim device sized for 48 inch openings, with a 1-3/4 inch to 2-1/4 inch door thickness range identical to the Precision 2108. The difference is function: the DORMA 9300 is cataloged exit only, while the 2108 is a center driven cam device that accepts 4908A, 4908B, 4908C, 4908D or 4908K lever trim and is field selectable for function. If the opening needs outside lever entry, the 2108 covers it directly; if the door is push-to-exit with no outside trim, the 9300 covers the same size and grade.
8) I need an exit device with a lever trim on a 36 inch door instead of a 48 inch one. What should I use?
The Dormakaba E2103 electrified rim exit device is a 36 inch device supplied with 4908A trim and an 08 classroom function, so it uses the same 4908-series lever trim family as the BEST Precision 2108 and the same classroom-style outside lever operation on a narrower opening. The 2108 is built for 48 inch openings, so a 36 inch leaf is outside its size. Confirm handing on either one, since the 2108 is reversible and ships RHRB standard.
9) I need electric latch retraction on a wide stile door. How does the BEST Precision 2108 compare to an electrified alternative?
The BEST Precision 2108 can be ordered with ELR electric latch retraction or MLR motorized latch retraction as a device option, along with latchbolt and touchbar monitoring switches, delayed egress and a wireless access management option, on a 48 inch wide stile device. The SDC S6136 is an alternative electrified architectural rim exit device, a 36 inch unit with a 4 inch wide stile and a 1-3/4 inch to 2 inch door thickness range. Choose on opening width and door thickness first: the 2108 covers 48 inch openings and doors to 2-1/4 inch.
10) Will the BEST Precision 2108 retrofit into an existing exit device's holes, or do I need to match the original brand?
The BEST Precision 2100 Series is designed to retrofit into other manufacturers' mounting hole locations, so a 48 inch wide stile opening currently carrying something like a Corbin Russwin ED5200 wide stile Grade 1 rim device or a Detex 10 Advantex wide stile rim device is a candidate for the 2108 without new door prep. Verify the existing hole pattern against the BEST template before drilling, and confirm door thickness falls in the 1-3/4 inch to 2-1/4 inch range.
11) Should I pick hex dogging or cylinder dogging on this exit device?
Three choices: hex dogging is the standard and is fine for most interior and back-of-house doors where staff hold the latch retracted with an allen key. Cylinder dogging is the pick when you want dogging controlled by a keyed cylinder so only keyholders can leave the door pushpull. Less dogging is ordered when policy or a future fire-rated swap means you do not want the door dogged at all.
12) What lever trim choices are there for the BEST Precision 2108, and can I buy the device alone?
Lever trim comes in five designs: 4908A, 4908B, 4908C, 4908D, and 4908K. You can also order the device with no trim at all if the outside is exit only or you already have trim on the door. Remember to call out LHR or RHR handing whenever a lever is selected.
13) Is the 2108 ANSI Grade 1, and is it UL Listed?
It is BHMA certified to ANSI 156.3 Grade 1 and UL Listed as panic and fire exit hardware, conforming to UL10C and UBC 7-2. Cover, touchbar, channel, filler, and end cap are heavy wrought brass, bronze, or stainless.
14) What other 48 inch wide stile rim exit devices could I use instead of the Precision 2108?
Comparable 48 inch wide stile rim devices include the DORMA 9300 Series exit only device, which also lists a 1-3/4 to 2-1/4 inch door thickness range, and the Corbin Russwin ED3000 Series 48 inch crossbar rim device at 1-3/4 inch doors. Sargent's 2828 and 3828 are Grade 1 reversible wide stile rim devices for 48 inch doors, both exit only. The key difference is that those are exit only or crossbar designs, while the 2108 is a touchbar device built to take 4908 lever trim and electrified options.
15) Can I change the function of the 2108 in the field, or do I have to order the exact function?
Functions are field selectable on the 2100 Series, with the exception of the double cylinder option, and the device ships set to the standard 03 function. That means one stocked device can cover several openings in a building, which is useful if you are standardizing hardware across a property.
16) What is a simpler 48 inch exit device if I do not need access control or lever trim?
For a plain push-to-exit 48 inch opening, the Sargent 2828 and Sargent 3828 are both Grade 1 reversible wide stile rim devices rated for 48 inch minimum door width and cataloged exit only, the 3828 with a standard push bar. The Corbin Russwin ED3200 is a Grade 1 48 inch wide stile crossbar rim device for 1-3/4 inch doors. All three drop the center driven cam and 4908 lever trim the BEST Precision 2108 carries for access control integration, so choose them only where no outside entry is required.
17) Can I put the BEST Precision 2108 on a wood door, and what should I use if not?
The BEST Precision 2108 is listed as not wood door compatible. Among rim exit devices that are wood door compatible, the Adams Rite 8700 Series is a Grade 1 narrow stile rim device rated for wood doors, and the Adams Rite 3700 Series is the fire rated Grade 1 version, also wood door compatible. Both are narrow stile, so verify the stile width on the wood leaf before ordering.
18) Is a Cal-Royal 5500 48 inch rim device the same thing as a BEST Precision 2108 48 inch?
They cover the same 48 inch opening but not the same specification. The Cal-Royal 5500 is a heavy duty Grade 2 rim exit device with a push bar. The BEST Precision 2108 is BHMA certified to ANSI 156.3 Grade 1 with a touchbar, heavy wrought brass, bronze or stainless steel components, and a center driven cam for access control trim. If the drawing calls for Grade 1, the Cal-Royal 5500 will not satisfy it.
19) What looks like a substitute for the BEST Precision 2108 but will not actually latch a door?
Two items in the rim exit family are not latching devices. The Detex Advantex 00 Series is a super-heavy-duty dummy exit device with wide stile design, and the Sargent 12-8810-LTRIM is cataloged with a dummy function. They match the touchbar appearance of the BEST Precision 2108 but do not provide the deadlocking latchbolt with 3/4 inch throw that the 2108 uses to secure the opening. Use a dummy only on the inactive leaf of a pair.
20) What finish should I order to match the rest of my openings?
Ten finishes are offered: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil-rubbed satin bronze, 622 matte black, 625 bright chrome, 626W satin chrome weatherized, 628 satin aluminum, 630 satin stainless, and 690 statuary dark bronze. For exterior doors that see weather, the 626W weatherized finish pairs naturally with the WTS or WTDS weatherized monitoring switches.
21) What is the difference between the BEST Precision 2108 touchbar and a crossbar rim device?
The BEST Precision 2108 uses a touchbar with a cover, touchbar, device channel, filler and end cap in heavy wrought brass, bronze or stainless steel. Crossbar devices carry a horizontal bar across the door instead: the CRL Jackson 1095 Series is a 48 inch crossbar rim panic device, wide stile and exit only, and the Corbin Russwin ED3200 is a Grade 1 48 inch wide stile crossbar rim device. Crossbar styling is often chosen to match existing hardware on an older building; the 2108 gives the flush touchbar look plus 4908 lever trim options.
22) Is the Cal-Royal A9820 48 inch rim exit device an alternative to the BEST Precision 2108?
The Cal-Royal A9820 is a 48 inch heavy duty rim exit device cataloged exit only with a Grade 2 spec value, so it fits the same door width but provides no outside trim. The BEST Precision 2108 is ANSI 156.3 Grade 1 and accepts 4908A through 4908K lever trim with a center driven cam sized for access control tailpieces needing at least 50 degrees of rotation. Match on grade and on whether outside entry is required.
